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.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
PRODUCTION DATA information is current as of publication date.
Products conform to specifications per the terms of Texas Instruments
standard warranty. Production processing does not necessarily include
testing of all parameters.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. 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. The package thermal impedance is calculated in accordance with JESD 51, except for through-hole packages, which use a trace
