The direction of data through these driver-receiver pairs is determined by the DC, TE, and SC enable signals. The SC input allows the REN and IFC transceivers to be controlled independently. 1 24 2 23 3 22 4 21 5 20 6 19 7 18 8 17 9 16 10 15 11 14 12 13 VCC NC REN IFC NDAC NRFD DAV EOI ATN SRQ NC DC Terminal I/O Ports N PACKAGE (TOP VIEW) description The SN75ALS162 eight-channel general-purpose interface bus (GPIB) transceiver is a monolithic, high-speed, advanced low-power Schottky process device designed to provide the bus-management and data-transfer signals between operating units of a multiple-controller instrumentation system. When combined with the SN75ALS160 octal bus transceiver, the SN75ALS162 provides the complete 16-wire interface for the IEEE 488 bus.

The drivers are designed to handle loads up to 48 mA of sink current. Each receiver features pnp transistor inputs for high input impedance and hysteresis of 400 mV minimum for increased noise immunity. All receivers have 3-state outputs to present a high impedance to the terminal when disabled. The SN75ALS162 is characterized for operation from 0°C to 70°C.
