ICC and IOZ reduced by 50% Guaranteed simultaneous switching noise level and

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 satisfying 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 SeriesTM technology to guarantee quiet output switching and improve dynamic threshold performance. features GTOTM output control and undershoot corrector in addition to a split ground bus for superior performance.
