SN75176BP: Bus Transceiver, Pinout, Circuit

The SN75176BP differential bus transceiver is a monolithic integrated circuit designed for two-way data communication on a multipoint bus transmission line. It is specially designed for balanced transmission lines and complies with ANSI standard EIA/TIA-422-B and ITU recommendation V.11.

SN75176BP combines a three-state differential line driver and a differential input line receiver, both of which are powered by a single 5V power supply. The driver and the receiver have high-level active and low-level active enable respectively, and they can be connected together externally for direction control. The driver differential output and receiver differential input are connected internally to form a differential input/output (I/O) bus port designed to provide a minimum load on the bus when the driver is disabled or VCC = 0. These ports have a wide positive and negative common-mode voltage range making the device suitable for party-line applications.

The driver is designed to handle loads that sink or source currents up to 60 mA. The driver has positive and negative current limiting and thermal shutdown functions to provide protection in the event of a line fault. Thermal shutdown is designed to occur at a junction temperature of approximately 150°C. The receiver has a minimum input impedance of 12 kΩ, input sensitivity of ±200 mV, and a typical input hysteresis of 50 mV.

SN75176BP can be used in transmission line applications using SN75172 and SN75174 quad differential line drivers and SN75173 and SN75175 quad differential line receivers. The interface type of SN75176BP is RS-485/RS-422, the operating temperature range is 0°C to +70°C, and the package type is DIP.
