description

The SN55ALS160 and SN75ALS160 eight-

channel

general-purpose

interface

bus

transceivers

are

monolithic,

high-speed,

advanced low-power Schottky (ALS) devices

designed for two-way data communications over

single-ended

transmission

lines.

They

are

designed to meet the requirements of IEEE

Standard 488 - 1978. The transceivers feature

driver outputs that can be operated in either the

passive-pullup or 3-state mode. If talk enable (TE) is high, these ports have the characteristics of passive-pullup

outputs when pullup enable (PE) is low and of 3-state outputs when PE is high. Taking TE low places these ports

in the high-impedance state. The driver outputs are designed to handle loads up to 48 mA of sink current.

An active turn-off feature has been incorporated into the bus-terminating resistors so that the device exhibits

SN75ALS162 bus management transceiver, the pair provides the complete 16-wire interface for the IEEE - 488

bus.

The SN55ALS160 is characterized for operation from – 55

°C to 125°C. The SN75ALS160 is characterized for

operation from 0

°C to 70°C.
