SGLS026A - MARCH 1989 - REVISED JUNE 1995
The SN95176B differential bus transceiver is a monolithic integrated circuit designed for bi-directional data communication on multipoint bus transmission lines. The transceiver is suitable for most RS-422-A and RS-485 applications to the extent of the specified data sheet characteristics and operating conditions.
The SN95176B combines a 3-state differential line driver and a differential input line receiver, both of which operate from a single 5-V power supply. The driver and receiver have active-high and active-low enables, respectively, that can be externally connected together to function as a direction control. The driver differential outputs and the receiver differential inputs are connected internally to form differential input/output (I/O) bus ports that are designed to offer minimum loading to the bus whenever the driver is disabled or VCC = 0. These ports feature wide positive and negative common-mode voltage ranges making the device suitable for party-line applications.
The driver is designed to handle loads up to 60 mA of sink or source current. The driver features positive- and negative-current limiting and thermal shutdown for protection from line fault conditions. Thermal shutdown is designed to occur at a junction temperature of approximately 150°C. The receiver features a minimum input impedance of 12 k
, an input sensitivity of ±200 mV, and a typical input hysteresis of 50 mV.
The SN95176B is characterized for operation from -40°C to 110°C.
