THE SN75177B IS NOT RECOMMENDED FOR NEW DESIGN
The SN75177B and SN75178B differential bus repeaters are monolithic integrated devices each designed for one-way data communication on multipoint bus transmission lines.These devices are designed for balanced transmission bus line
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.
