74ACQ646 • 74ACTQ646 Quiet Series Octal Transceiver/Register with 3-STATE Outputs January 1990 Revised September 2000 74ACQ646 74ACTQ646 Quiet Series Octal Transceiver/Register with 3-STATE Outputs General Description Features The ACQ/ACTQ646 consist of registered bus transceiverGuaranteed simultaneous switching noise level and circuits, with outputs, D-type flip-flops, and control circuitry dynamic threshold performance providing multiplexed transmission of data directly from theGuaranteed pin-to-pin skew AC performance input bus or from the internal storage registers. Data on the Independent registers for A and B busses A or B bus will be loaded into the respective registers on Multiplexed real-time and stored data transfers the LOW-to-HIGH transition of the appropriate clock pin (CPAB or CPBA). The four fundamental handling functions300 mil slim dual-in-line package available are illustrated in Figure 1, Figure 2, Figure 3 andOutputs source/sink 24 mA Figure 4. Faster prop delays than the standard AC/ACT646 The ACQ/ACTQ utilizes Fairchild Quiet Series technol- ogy to guarantee quiet output switching and improved dynamic threshold performance. FACT Quiet Series fea- tures GTO output control and undershoot corrector in addition to a split ground bus for superior performance.
