74F652
Transceivers/Registers
General Description
These devices consist of bus transceiver circuits with
D-type flip-flops, and control circuitry arranged for multi-
plexed transmission of data directly from the input bus or
from internal registers. Data on the A or B bus will be
clocked into the registers as the appropriate clock pin goes
to HIGH logic level. Output Enable pins (OEAB, OEBA) are
provided to control the transceiver function.
Features
s Independent registers for A and B buses
s Multiplexed real-time and stored data
s 74F652 non-inverting data path
