SN75178B, SN75177B, DIFFERENTIAL BUS REPEATERS

SN75177B, SN75178B DIFFERENTIAL BUS REPEATERS * Meets EIA Standards RS-422-A and RS-485 and CCITT Recommendations V.11 and X.27 * Des.
SLLS002C. D2606, JULY 1985. REVISED FEBRUARY 1993 SN75177B .

Features

* high input impedance, input hysteresis for increased noise immunity, and input sensitivity of ± 200 mV over a common-mode input voltage range of
* 7 V to 12 V. The driver features thermal shutdown for protection from line fault conditions. Thermal shutdown is designed to occur at a junction

Applications

* and meet EIA Standard RS-422-A and RS-485 and CCITT Recommendations V.11 and X.27. Each device is designed to improve the performance of the data communication over long bus lines. The SN75177B and SN75178B are identical except for the complementary enable inputs, which allow the devices to be used
