SN65LBC176P Datasheet PDF - TI

●The SN65LBC176P is a monolithic differential Bus Transceiver designed for bidirectional data communication on multipoint bus-transmission lines. It is designed for balanced transmission lines and meets ANSI standard TIA/EIA-485-A (RS-485) and ISO 8482:1987(E). It combines a 3-state, differential line driver and a differential input line receiver, both of which operate from a single 5V 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.

● Very low device supply current can be achieved by disabling the driver and the receiver

● Low skew

● Designed for multi-point bus transmission on long bus lines in noisy environments

● Wide positive and negative input/output bus voltage ranges

● Thermal-shutdown protection

● Driver positive-and negative-current limiting

● Open-circuit failsafe receiver design

● Glitch-free power-up and power-down protection

● 200µA Maximum very low disabled supply current

● ±200mV Maximum receiver input sensitivity

● 50mV Typical receiver input hysteresis
