DB, DW, N, OR PW PACKAGE (TOP VIEW) UART and Serial-Port Connector of IBM PC/AT and Compatibles Meet or Exceed the Requirements of TIA/EIA-232-F and ITU v.28 Standards Designed to Support Data Rates up to 120 kbit/s Pinout Compatible With SN75C185 and SN75185 VDD RA1 RA2 RA3 DY1 DY2 RA4 DY3 RA5 VSS description/ordering information 1 20 2 19 3 18 4 17 5 16 6 15 7 14 8 13 9 12 10 11 VCC RY1 RY2 RY3 DA1 DA2 RY4 DA3 RY5 GND The GD65232 and GD75232 combine three drivers and five receivers from the Texas Instruments trade-standard SN75188 and SN75189 bipolar quadruple drivers and receivers, respectively. The pinout matches the flow-through design of the SN75C185 to decrease the part count, reduce the board space required, and allow easy interconnection of the UART and serial-port connector of an IBM PC/AT and compatibles. The bipolar circuits and processing of the GD65232 and GD75232 provide a rugged, low-cost solution for this function at the expense of quiescent power and external passive components relative to the SN75C185. The GD65232 and GD75232 comply with the requirements of the TIA/EIA-232-F and ITU (formerly CCITT) V.28 standards. These standards are for data interchange between a host computer and a peripheral at signaling rates up to 20 kbit/s. The switching speeds of these devices are fast enough to support rates up to 120 kbit/s with lower capacitive loads (shorter cables). Interoperability at the higher signaling rates cannot be expected unless the designer has design control of the cable and the interface circuits at both ends. For interoperability at signaling rates up to 120 kbit/s, use of TIA/EIA-423-B (ITU V.10) and TIA/EIA-422-B (ITU V.11) standards is recommended.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTES: 1. All voltages are with respect to the network ground terminal. 2. Maximum power dissipation is a function of TJ(max), qJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) − TA)/qJA. Operating at the absolute maximum TJ of 150°C can affect reliability. 3. The package thermal impedance is calculated in accordance with JESD 51-7. POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 3
