SN75LBC171DBG4

IC TRPL DIFF TXRX 20-SSOP

description

The SN65LBC171 and SN75LBC171 are monolithic integrated circuits designed for bidirectional data communication on multipoint bus-transmission lines. Potential applications include serial or parallel data transmission, cabled peripheral buses with twin axial, ribbon, or twisted-pair cabling. These devices are suitable for FAST–20 SCSI and can transmit or receive data pulses as short as 25 ns, with skew less than 3 ns.

These devices combine three 3-state differential line drivers and three differential input line receivers, all of which operate from a single 5-V power supply.
