Data on the A or B bus 74F646/74F646B have non-inverting data paths will be clocked into the registers as the appropriate clock pin goes to a high logic level. Control G and direction pins74F646B is a faster version of the 74F646 are provided to control the transceiver function. In the3-STATE outputs transceiver mode, data present at the high impedance port 300 mil slim DIP 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.
