Octal Bus Transceiver and Register with 3-STATE Outputs
74F646 • 74F646B • 74F648 Octal Transceiver/Register with 3-STATE Outputs March 1988 Revised August 1999 74F646 • 74F646B • 74F648 Octal Transceiver/Register with 3-STATE Outputs General Description Features These devices consist of bus transceiver circuits with 3- � Independent registers for A and B buses STATE, D-type flip-flops, and control circuitry arranged for � Multiplexed real-time and stored data multiplexed transmission of data directly from the input bus � 74F648 has inverting data paths or from the internal registers. Data on the A or B bus will be � 74F646/74F646B have non-inverting data paths clocked into the registers as the appropriate clock pin goes to a high logic level. Control G and direction pins are pro- � 74F646B is a faster version of the 74F646 vided to control the transceiver function. In the transceiver � 3-STATE outputs mode, data present at the high impedance port may be � 300 mil slim DIP stored in either the A or the B register or in both. The select controls can multiplex stored and real-time (transparent mode) data. The direction control determines which bus will receive data when the enable control G is Active LOW. In the isolation mode (control G HIGH), A data may be stored in the B register and/or B data may be stored in the A register.
