μ
A in high
and low states)
Independent registers for A and B buses
Multiplexed real-time and stored data
Choice of non-inverting and inverting data paths
3-State outputs
Industrial temperature range available (–40

74F652A
DESCRIPTION
The 74F651A and 74F652A 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 (OEAB, OEBA) and select (SAB, SBA)
pins are provided for bus management.
