Download the SN75178B datasheet PDF. This datasheet also covers the SN75177B variant, as both devices belong to the same differential bus repeaters family and are provided as variant models within a single manufacturer datasheet.

Description

SLLS002C D2606, JULY 1985

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 temperature of approximately 150°C. The driver is designed to drive current loads up to 60 mA maximum. The SN75177B and SN75178B are designed for optimum performance when used on transmission buses e.
