74ACQ241  54ACTQ 74ACTQ241
Quiet Series Octal Buffer Line Driver
with TRI-STATE Outputs
General Description
The ’ACQ ’ACTQ241 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 SeriesTM features GTOTM output control and
undershoot corrector in addition to a split ground bus for
superior performance
Features
Y ICC and IOZ reduced by 50%
Y Guaranteed simultaneous switching noise level and
dynamic threshold performance
Y Guaranteed pin-to-pin skew AC performance
Y Improved latch-up immunity
Y TRI-STATE outputs drive bus lines or buffer memory
address registers
Y Outputs source sink 24 mA
Y Faster prop delays than the standard ’AC ’ACT241
Y 4 kV minimum ESD immunity (’ACTQ)
Y Standard Military Drawing (SMD)
