74ABT652 Octal Transceivers and Registers with 3-STATE Outputs November 1992 Revised January 1999 74ABT652 Octal Transceivers and Registers with 3-STATE Outputs General Description The ABT652 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 the internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes to HIGH logic level. Output Enable pins (OEAB, OEBA) are provided to control the transceiver function. Features s Independent registers for A and B buses s Multiplexed real-time and stored data s A and B output sink capability of 64 mA, source capability of 32 mA s Guaranteed output skew s Guaranteed multiple output switching specifications s Output switching specified for both 50 pF and 250 pF loads s Guaranteed simultaneous switching noise level and dynamic threshold performance s Guaranteed latchup protection s High ...
