description
The SN75196 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 SN75196 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 SN75196 provide a rugged, low-cost solution for this
function.
The SN75196 complies with the requirements of TIA/EIA-232-F and ITU (formerly CCITT) V.28 standards.
These standards are for data interchange between a host computer and peripheral at signal rates of up to
20 kbit/s. The switching speeds of the SN75196 are fast enough to support rates of 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 of up to 120 kbit/s, use of TIA/EIA-423-B (ITU V.10) and TIA/EIA-422-B (ITU V.11) standards are
recommended.
The SN75196 is characterized for operation over a temperature range of 0°C to 70°C.

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.
