74ACTQ652 Quiet Transceiver/Register 74ACTQ652 Quiet Transceiver/Register The ACTQ652 consists of bus transceiver circuits with Dtype flip-flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or from internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes to the HIGH logic level. Output Enable pins OEAB, OEBA are provided to control the transceiver function.
