description

The SN75ALS171 and the SN75ALS171A triple 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 each driver meets ANSI Standards EIA/TIA-422-B and RS-485 and both the

drivers and receivers meet ITU Recommendation V.11. The SN75ALS171A 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 SN75ALS171 and the SN75ALS171A operate from a single 5-V power supply. The drivers and receivers

have individual active-high and active-low enables, respectively, which can be externally connected together

to function as a direction control. The driver differential output and the receiver differential input pairs are

connected internally to form differential input/output (I/O) bus ports that are designed to offer minimum loading

to the bus when the driver is disabled or V

common-mode voltage ranges making the device suitable for party-line applications.

is at 0 V. These ports feature wide positive and negative

The SN75ALS171 and the SN75ALS171A are characterized for operation from 0°C to 70°C.
