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
and receiver outputs. The outputs do not load the bus when VCC = 0. When combined with the SN75161B or
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.

The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.
OBSOLETE: TI has discontinued the production of the device.
(2)
RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may
reference these types of products as "Pb-Free".
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of
