74ACQ373 • 74ACTQ373
Quiet Series
 Octal Transparent Latch
with 3-STATE Outputs
General Description
The ACQ/ACTQ373 consists of eight latches with 3-STATE
outputs for bus organized system applications. The latches
appear transparent to the data when Latch Enable (LE) is
HIGH. When LE is LOW, the data satisfying the input tim-
ing requirements is latched. Data appears on the bus when
the Output Enable (OE) is LOW. When OE is HIGH, the
bus output is in the HIGH impedance state.
The ACQ/ACTQ373 utilizes Fairchild Quiet Series
 tech-
nology to guarantee quiet output switching and improve
dynamic threshold performance. features GTO
 output
control and undershoot corrector in addition to a split
ground bus for superior performance.
Features
s ICC and IOZ reduced by 50%
s Guaranteed simultaneous switching noise level and
dynamic threshold performance
s Guaranteed pin-to-pin skew AC performance
s Improved latch up immunity
s Eight latches in a single package
s 3-STATE outputs drive bus lines or buffer memory
address registers
s Outputs source/sink 24 mA
s Faster prop delays than the standard AC/ACT373
Ordering Code:
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering code.
