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. WhencombinedwiththeSN75160Boctal  
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 power-  
up/-down disable circuit is included on all bus and  
receiver outputs. This provides glitch-free opera-
