description

The SN75161B and SN75162B eight-channel,

general-purpose interface bus transceivers are

monolithic, high-speed, low-power Schottky

devices designed to meet the requirements of

IEEE Standard 488-1978. Each transceiver is

designed to provide the bus-management and

data-transfer signals between operating units of

a single- or multiple-controller instrumentation

system. When combined with the SN75160B octal

bus transceiver, the SN75161B or SN75162B

provides the complete 16-wire interface for the

IEEE-488 bus.

The SN75161B and SN75162B feature eight

driver-receiver pairs connected in a front-to-back

configuration to form input/output (I/O) ports at

both the bus and terminal sides. A powerup/-

down disable circuit is included on all bus and

receiver outputs. This provides glitch-free operation

during VCC power up and power down.
