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.
dynamic threshold performance
Guaranteed pin-to-pin skew AC performance
Improved latch up immunity
Eight latches in a single package
3-STATE outputs drive bus lines or buffer memory
address registers
Outputs source/sink 24mA
Faster prop delays than the standard AC/ACT373
