Quiet Series Octal Buffer/Line Driver

with TRI-STATE Outputs

General Description

Features

and I

reduced by 50%

The ’ACQ/’ACTQ244 is an octal buffer and line driver de-

signed to be employed as a memory address driver, clock

driver and bus oriented transmitter or receiver which pro-

vides improved PC board density. The ACQ/ACTQ utilizes

NSC Quiet Series technology to guarantee quiet output

switching and improved dynamic threshold performance.

FACT Quiet Series^TMfeatures GTO^TMoutput control and

undershoot corrector in addition to a split ground bus for

superior performance.

Guaranteed simultaneous switching noise level and

dynamic threshold performance

Guaranteed pin-to-pin skew AC performance

Improved latch-up immunity

TRI-STATE outputs drive bus lines or buffer memory

address registers

Outputs source/sink 24 mA

Faster prop delays than the standard ’AC/’ACT244

4 kV minimum ESD immunity

Standard Military Drawing (SMD)
