description

The GD75323 combines five drivers and three receivers from the trade-standard SN75188 and SN75189

bipolar quadruple drivers and receivers, respectively. The flow-through design of the GD75323 decreases the

part count, reduces the board space required, and allows easy interconnection of the UART and serial-port

connector. The all-bipolar circuits and processing of the GD75323 provide a rugged, low-cost solution for this

function.

The GD75323 complies with the requirements of the ANSI 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 signal rates

up to 20 kbit/s. The switching speeds of the GD75323 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 assured 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 ANSI Standard TIA/EIA-423-B and TIA/EIA-422-B and ITU Recommendations V.10

and V.11 are recommended.

The GD75323 is characterized for operation over a temperature range of 0°C to 70°C.
