74ACQ373 • 74ACTQ373 Quiet Series Octal Transparent Latch with 3-STATE Outputs July 1989 Revised November 1999 74ACQ373 74ACTQ373 Quiet Series Octal Transparent Latch with 3-STATE Outputs General Description Features The ACQ/ACTQ373 consists of eight latches with 3-STATEI and I reduced by 50% CC OZ outputs for bus organized system applications. The latches Guaranteed simultaneous switching noise level and appear transparent to the data when Latch Enable (LE) is dynamic threshold performance HIGH. When LE is LOW, the data satisfying the input tim- Guaranteed pin-to-pin skew AC performance ing requirements is latched. Data appears on the bus when Improved latch up immunity the Output Enable (OE) is LOW. When OE is HIGH, the bus output is in the HIGH impedance state.Eight latches in a single package The ACQ/ACTQ373 utilizes Fairchild Quiet Series tech-3-STATE outputs drive bus lines or buffer memory nology to guarantee quiet output switching and improve address registers dynamic threshold performance. features GTO output Outputs source/sink 24 mA control and undershoot corrector in addition to a split Faster prop delays than the standard AC/ACT373 ground bus for superior performance.
