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.
