Quiet Series Octal Latch with 3-STATE Outputs
General Description
Features
n ICC and IOZ reduced by 50%
The ACQ/ACTQ573 is a high-speed octal latch with buffered
common Latch Enable (LE) and buffered common Output
Enable (OE) inputs. The ACQ/ACTQ573 is functionally iden-
tical to the ACQ/ACTQ373 but with inputs and outputs on op-
posite sides of the package. The ACQ/ACTQ utilizes Fair-
n Guaranteed simultaneous switching noise level and
dynamic threshold performance
n Guaranteed pin-to-pin skew AC performance
n Improved latch-up immunity
n Inputs and outputs on opposite sides of package allow
easy interface with microprocessors
n Outputs source/sink 24 mA
™
child’s Quiet Series technology to guarantee quiet output
switching and improved dynamic threshold performance.

™
FACT Quiet Series features GTO output control and un-
dershoot corrector in addition to a split ground bus for supe-
rior performance.
n Faster prop delays than standard AC/ACT573
n 4 kV minimum ESD immunity
