description/ordering information

The SN65LBC176A-EP differential bus transceiver is a monolithic, integrated circuits designed for bidirectional

data communication on multipoint bus-transmission lines. The SN65LBC176A-EP is designed for balanced

transmission lines and is compatible with ANSI standard TIA/EIA-485-A and ISO 8482. The SN65LBC176A-EP

offers improved switching performance over its predecessors without sacrificing significantly more power.

The SN65LBC176A-EP 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, which can externally connect together to function as a direction control. The driver differential

outputs and the receiver differential inputs connect internally to form a differential input/output (I/O) bus port that

is designed to offer minimum loading to the bus whenever the driver is disabled or VCC = 0. This port features

wide positive and negative common-mode voltage ranges, making the device suitable for party-line

applications. Low device supply current can be achieved by disabling the driver and the receiver.
