The SN74LVC1G66 device can handle analog and digital signals. The device permits bidirectional transmission of signals with amplitudes of up to 5.5 V (peak). Like all analog switches, the SN74LVC1G66 is bidirectional. NanoFree package technology is a major breakthrough in IC packaging concepts, using the die as the package. 8.2 Functional Block Diagram 1 2 A B 4 C Figure 10. Logic Diagram (Positive Logic) 8.3 Feature Description The TI NanoFree package is one of TI’s smallest packages and allows customers to save board space while the solder bumps allow for easy testing. The SN74LVC1G66 has a wide VCC range, allowing rail-to-rail operation of signals anywhere from a 1.8-V system to a 5-V system. In addition, the control input (C Pin) is 5.5-V tolerant, allowing higher-voltage logic to interface to the switch control system. 8.4 Device Functional Modes 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. 9.1 Application Information The SN74LVC1G66 can be used in any situation where an SPST switch would be used and a solid-state, voltage-controlled version is preferred. 9.2 Typical Application 2.5 V C or System Logic C VCC A To/From System B GND Figure 11. Typical Application Schematic 9.2.1 Design Requirements The SN74LVC1G66 allows on and off control of analog and digital signals with a digital control signal. All input signals should remain between 0 V and VCC for optimal operation. 9.2.2 Detailed Design Procedure 1. Recommended Input Conditions: – For rise time and fall time specifications, see Δt/Δv in Recommended Operating Conditions. – For specified high and low levels, see VIH and VIL in Recommended Operating Conditions. – Inputs and outputs are overvoltage tolerant allowing them to go as high as 5.5 V at any valid VCC. 2. Recommended Output Conditions: – Load currents should not exceed ±50 mA. 3. Frequency Selection Criterion: – Maximum frequency tested is 150 MHz. – Added trace resistance/capacitance can reduce maximum frequency capability; use layout practices as directed in Layout. 14 Submit Documentation Feedback Copyright © 2001–2017, Texas Instruments Incorporated Product Folder Links: SN74LVC1G66 SN74LVC1G66 www.ti.com SCES323Q – JUNE 2001 – REVISED MARCH 2017 Typical Application (continued) 9.2.3 Application Curve 20 15 ron 85°C 10 25°C −40°C 5 0 0 1 2 3 VI Figure 12. ron vs VI, VCC = 2.5 V (SN74LVC1G66) 10 Power Supply Recommendations The power supply can be any voltage between the minimum and maximum supply voltage rating located in the Recommended Operating Conditions. Each VCC terminal should have a good bypass capacitor to prevent power disturbance. For devices with a single supply, a 0.1-μF bypass capacitor is recommended. If there are multiple pins labeled VCC, then a 0.01-μF or 0.022-μF capacitor is recommended for each VCC because the VCC pins will be tied together internally. For devices with dual supply pins operating at different voltages, for example VCC and VDD, a 0.1-µF bypass capacitor is recommended for each supply pin. It is acceptable to parallel multiple bypass capacitors to reject different frequencies of noise. 0.1-μF and 1-μF capacitors are commonly used in parallel. The bypass capacitor should be installed as close to the power terminal as possible for best results. 11 Layout 11.1 Layout Guidelines Reflections and matching are closely related to loop antenna theory, but different enough to warrant their own discussion. When a PCB trace turns a corner at a 90° angle, a reflection can occur. This is primarily due to the change of width of the trace. At the apex of the turn, the trace width is increased to 1.414 times its width. This upsets the transmission line characteristics, especially the distributed capacitance and self–inductance of the trace — resulting in the reflection. It is a given that not all PCB traces can be straight, and so they will have to turn corners. Figure 13 shows progressively better techniques of rounding corners. Only the last example maintains constant trace width and minimizes reflections.
