Quad TRI-STATE Buffers

General Description

This device contains four independent gates each of which

performs a non-inverting buffer function. The outputs have

the TRI-STATE feature. When enabled, the outputs exhibit

the low impedance characteristics of a standard LS output

with additional drive capability to permit the driving of bus

lines without external resistors. When disabled, both the

output transistors are turned off presenting a high-imped-

ance state to the bus line. Thus the output will act neither as

a significant load nor as a driver. To minimize the possibility

that two outputs will attempt to take a common bus to oppo-

site logic levels, the disable time is shorter than the enable

time of the outputs.

Features

Alternate Military/Aerospace device (54LS125) is avail-

able. Contact a National Semiconductor Sales Office/

Distributor for specifications.
