SN75LBC176A 四路 RS-485 差动线路驱动器

The SN65LBC176A, SN65LBC176AQ, and SN75LBC176A differential bus transceivers are monolithic, integrated circuits designed for bidirectional data communication on multipoint bus-transmission lines. They are designed for balanced transmission lines and are compatible with ANSI standard TIA/EIA-485-A and ISO 8482. The A version offers improved switching performance over its predecessors without sacrificing significantly more power.

The SN65LBC176A, SN65LBC176AQ, and SN75LBC176A combine 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.
