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 SN75ALS162 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. 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.

The driver outputs (GPIB I/O ports) feature active bus-terminating resistor circuits designed to provide a high

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.
