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.

PRODUCTION DATA information is current as of publication date.

standard warranty. Production processing does not necessarily include

testing of all parameters.
