This standard logic function has a common pinout, direction select pin, and active-low output enable. When the outputs are disabled, the A and B sides of the device are effectively isolated. 9.2 Functional Block Diagram DIR 1 19 A1 OE 2 18 B1 To Seven Other Channels Copyright © 2016, Texas Instruments Incorporated Figure 3. Logic Diagram (Positive Logic) 9.3 Feature Description 9.3.1 3-State outputs The 3-state outputs can drive bus lines directly. All outputs can be put into high impedance mode through the OE pin. 9.3.2 PNP Inputs This device has PNP inputs which reduce dc loading on bus lines. 9.3.3 Hysteresis on Bus Inputs The bus inputs have built-in hysteresis that improves noise margins. 9.4 Device Functional Modes The SNx4LS245 performs the standard '245 logic function. Data can be transmitted from A to B or from B to A depending on the DIR pin value, or the A and B sides can be isolated from one another by setting the OE pin HIGH. 8 Submit Documentation Feedback Copyright © 1976–2016, Texas Instruments Incorporated Product Folder Links: SN54LS245 SN74LS245 SN54LS245, SN74LS245 www.ti.com SDLS146B – OCTOBER 1976 – REVISED SEPTEMBER 2016 Table 1.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 10.1 Application Information The SNx4LS245 is commonly used to drive ribbon cables or back plane busses. It allows isolation from the bus when necessary, and increases drive strength on the bus. 10.2 Typical Application Figure 5 shows the SNx4LS245 wired up as a permanently enabled data bus transceiver for both a master and slave device communicating over a ribbon cable or back plane.

SNx4LS245 Being Used to Communicate Over a Ribbon Cable or Back Plane 10.2.1 Design Requirements This device uses Schottky transistor logic technology. Take care to avoid bus contention because it can drive currents that would exceed maximum limits. The high drive creates fast edges into light loads, so routing and load conditions must be considered to prevent ringing. 10.2.2 Detailed Design Procedure • Power Supply – Each device must maintain a supply voltage between 4.5 V and 5.5 V • Inputs – Input signals must meet the VIH and VIL specifications in Electrical Characteristics – Inputs leakage values (II, IIH, IIL) from Electrical Characteristics must be considered • Outputs – Output signals are specified to meet the VOH and VOL specifications in Electrical Characteristics as a minimum (the values could be closer to VCC for high signals or GND for low signals) – TI recommends maintaining output currents as specified in Recommended Operating Conditions – The part can be damaged by sourcing or sinking too much current. See Electrical Characteristics for details. 10 Submit Documentation Feedback Copyright © 1976–2016, Texas Instruments Incorporated Product Folder Links: SN54LS245 SN74LS245 SN54LS245, SN74LS245 www.ti.com SDLS146B – OCTOBER 1976 – REVISED SEPTEMBER 2016 Typical Application (continued) 10.2.3 Application Curve It is common to see significant losses in ribbon cables and back planes. Figure 6 shows a simplified simulation of a ribbon cable from a 5-V, 10-MHz low-drive strength source. It shows the difference between an input signal from a weak driver like an MCU or FPGA compared to a strong driver like the SN74LS245 when measured at the distant end of the cable. By adding a high-current drive transceiver before the cable, the signal strength can be significantly improved, and subsequently the cable can be longer. 5.5 Unbuffered SN74LS245 4.5 Voltage (V) 3.5 2.5 1.5 0.5 -0.5 0 100 200 300 Time (ns) 400 500 D001 Unbuffered line is directly connected to low current source, SN74LS245 line is buffered through the transceiver.

Each VCC pin must have a good bypass capacitor to prevent power disturbance. For devices with a single supply, TI recommends a 0.1-µF bypass capacitor. If there are multiple VCC pins, TI recommends a 0.01-µF or 0.022-µF bypass capacitors for each power pin. It is acceptable to parallel multiple bypass capacitors to reject different frequencies of noise. Two bypass capacitors of value 0.1 µF and 1 µF are commonly used in parallel. For best results, install the bypass capacitor(s) as close to the power pin as possible. 12 Layout 12.1 Layout Guidelines When using multiple bit logic devices, inputs must not be left floating. In many applications, some channels of the SNx4LS245 are unused, and thus must be terminated properly. Because each transceiver channel pin can be either an input or an output, they must be treated as both when being terminated. Ground or VCC (whichever is more convenient) can be used to terminate unused inputs; however, each unused channel should be terminated to the same logic level on both the A and B side. For example, in Figure 7 unused channels 4, 5, 6, and 7 are terminated correctly with both sides connected to the same voltage, while channel 8 is terminated incorrectly with each side being tied to a different voltage. The OE input is also unused in this example, and is terminated directly to ground to permanently enable all outputs. 12.2 Layout Example DIR Device 1 SNx4LS245 OE A1 B1 A2 B2 A3 B3 A4 B4 A5 B5 A6 B6 A7 B7 A8 B8 GND Correctly Terminated Device 2 VCC Incorrectly Terminated Figure 7.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
