The SN75ALS170 and SN75ALS170A triple differential bus transceivers are monolithic integrated circuits designed for bidirectional data munication on multipoint bus transmission lines. It is designed for balanced transmission lines and the driver meets ANSI Standards EIA/TIA-422-B and RS-485 and both the driver and receiver meet ITU Remendation V.11. The SN75ALS170A is designed for FAST-20 SCSI and can transmit or receive data pulses as short as 30 ns with a maximum skew of 5 ns.
The SN75ALS170 and SN75ALS170A operate from a single 5-V power supply. The drivers and receivers have active-high and...
