54ACQ573 • 54ACTQ573

Quiet Series Octal Latch with TRI-STATE^®Outputs

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

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 Series features GTO output control and un-

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

rior performance.
