1 / 9 page © 1999 Fairchild Semiconductor Corporation DS009580 www.fairchildsemi.com March 1988 Revised August 1999 74F646 • 74F646B • 74F648 Octal Transceiver/Register with 3-STATE Outputs General Description These devices consist of bus transceiver circuits with 3- STATE, D-type 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 a high logic level. Control G and direction pins are pro- vided to control the transceiver function. In the transceiver mode, data present at the high impedance port may be 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. Features s Independent registers for A and B buses s Multiplexed real-time and stored data s 74F648 has inverting data paths s 74F646/74F646B have non-inverting data paths s 74F646B is a faster version of the 74F646 s 3-STATE outputs s 300 mil slim DIP Ordering Code: Devices also available in Tape and Reel. Specify by appending the suffix letter “X” to the ordering code.
