Octal Transceiver/Register with 3-STATE Outputs  
General Description  
Features  
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.  
Independent registers for A and B buses  
Multiplexed real-time and stored data  
74F648 has inverting data paths  
74F646/74F646B have non-inverting data paths  
74F646B is a faster version of the 74F646
