General Description
These devices consistof bus transceiver circuits with
D-type flip-flops, and control circuitry arrangedfor multi-
plexed transmissionof data directly fromthe inputbusor
from internal registers. DataontheAorB buswillbe
clockedintothe registersasthe appropriate clockpin goes HIGH logic level. Output Enable pins (OEAB, OEBA)are
providedto controlthe transceiver function.
Features Independent registersforAandB buses Multiplexed real-time and stored data Choiceof non-inverting and inverting data paths ’F651 inverting ’F652 non-inverting Guaranteed 4000V minimum ESD protection
