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 satisfy-

ing the input timing 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™

technology to guarantee quiet output switching and

improve

dynamic

threshold

performance.

features

GTO™ output control and undershoot corrector in addi-

tion to a split ground bus for superior performance.

Ordering Information

Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.
