74F646 Description
The 74F646/74F646A and 74F648/74F648A transceivers/registers consist of bus transceiver circuits with 3 state outputs, D type flip flops, and control circuitry arranged for multiplexed transmission of data directly from the input bus or the internal registers. Data on the A or B bus will be clocked into the registers as the appropriate clock pin goes high. Output enable (OE) and DIR pins are provided to control the...
