SN75ALS162 Datasheet | Texas Instruments

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 bined with the SN75ALS160 octal bus transceiver, the SN75ALS162 provides the plete 16-wire interface for the IEEE 488 bus.

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. - No internal connection The driver outputs (GPIB I/O ports) feature active bus-terminating resistor circuits designed to provide a high impedance to the bus when VCC = 0. The drivers are designed to handle loads up to 48 m A of sink current. Each receiver features pnp transistor inputs for high input impedance and hysteresis of 400 m V 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.
