The SN75161BN is an octal general-purpose Interface Bus Transceiver designed to meet the requirements of IEEE Standard 488-1978. The monolithic high-speed low-power Schottky device is designed to provide the bus-management and data-transfer signals between operating units of a single- or multiple-controller instrumentation system. It features 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 operation during VCC power up and power down. The direction of data through this driver-receiver pairs is determined by the DC, TE and SC (on SN75162B) enables signals. The driver outputs (GPIB I/O ports) feature active bus-terminating resistor circuits designed to provide high impedance to the bus when supply voltage VCC is 0. The driver is designed to handle loads up to 48mA of sink current.
