SN65LBC171, SN75LBC171 TRIPLE DIFFERENTIAL TRANSCEIVERS SLLS460A – NOVEMBER 2000 – REVISED FEBRUARY 2001 D Three Differential Transceivers in One Package D Signaling Rates1 Up to 30 Mbps D Low Power and High Speed D Designed for TIA/EIA-485, TIA/EIA-422, ISO 8482, and ANSI X3.277 (HVD SCSI Fast–20) Applications D Common-Mode Bus Voltage Range –7 V to 12 V D ESD Protection on Bus Terminals Exceeds 12 kV D Driver Output Current up to ±60 mA D Thermal Shutdown Protection D Driver Positive and Negative Current Limiting D Power-Up, Power-Down Glitch-Free Operation D Pin-Compatible With the SN75ALS171 D Available in Shrink Small-Outline Package 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.
