54ACTQ573
Quiet Series Octal Latch with TRI-STATE® Outputs
General Description
The ’ACQ/’ACTQ573 is a high-speed octal latch with buff-
ered common Latch Enable (LE) and buffered common Out-
put Enable (OE) inputs. The ’ACQ/’ACTQ573 is functionally
identical to the ’ACQ/’ACTQ373 but with inputs and outputs
on opposite sides of the package. The ’ACQ/’ACTQ utilizes
NSC Quiet Series technology to guarantee quiet output
switching and improved dynamic threshold performance.
FACT Quiet Seriesfeatures GTOoutput control and un-
dershoot corrector in addition to a split ground bus for supe-
rior performance.
Features
n ICC and IOZ reduced by 50%
n Guaranteed simultaneous switching noise level and
dynamic threshold 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
n Faster prop delays than standard ’ACT573
n 4 kV minimum ESD immunity
n Standard Microcircuit Drawing (SMD)
— ’ACTQ573: 5962-92194
— ’ACQ573: 5962-92180
