Quiet Series Octal Buffer/Line Driver with TRI-STATE^®

Outputs

n Guaranteed simultaneous switching noise level and

dynamic threshold performance

General Description

The ’ACQ/’ACTQ240 is an inverting octal buffer and line

n Improved latch-up immunity

driver designed to be employed as a memory address driver,

n Inverting TRI-STATE outputs drive bus lines or buffer

clock driver and bus oriented transmitter or receiver which

memory address registers

provides improved PC board density. The ’ACQ/’ACTQ uti-

lizes NSC Quiet Series technology to guarantee quiet output

switching and improve dynamic threshold performance.

n Outputs source/sink 24 mA

n Faster prop delays than the standard ’ACT240

n 4 kV minimum ESD immunity

n Standard Microcircuit Drawing (SMD)

’ACTQ240: 5962-92184

™

FACT Quiet Series features GTO output control and un-

dershoot corrector in addition to a split ground bus for supe-

rior performance.
