description

The SN75160B 8-channel general-purpose interface bus (GPIB) transceiver is a monolithic, high-speed,

low-power Schottky device designed for two-way data communications over single-ended transmission lines.

It is designed to meet the requirements of IEEE Standard 488-1978. The transceiver features driver outputs that

can be operated in either the passive-pullup or 3-state mode. If talk enable (TE) is high, these ports have the

characteristics of passive-pullup outputs when pullup enable (PE) is low and of 3-state outputs when PE is high.

Taking TE low places these ports in the high-impedance state. The driver outputs are designed to handle loads

up to 48 mA of sink current.

Output glitches during power up and power down are eliminated by an internal circuit that disables both the bus

SN75162B management bus transceivers, the pair provides the complete 16-wire interface for the IEEE-488

bus.

The SN75160B is characterized for operation from 0

°C to 70°C.
