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
Y Independent registers for A and B buses
Y Multiplexed real-time and stored data
Y Choice of non-inverting and inverting data paths
’F651 inverting
’F652 non-inverting
Y Guaranteed 4000V minimum ESD protection
