74FR543
Octal Latched Transceiver with 3-STATE Outputs
General Description
The 74FR543 octal transceiver contains two sets of D-type
latches for temporary storage of data flowing in either
direction. Separate Latch Enable and Output Enable inputs
are provided for each register to permit independent con-
trol of inputting and outputting in either direction of data
flow. Both the A and B outputs will source 15 mA and sink
64 mA.
Features
s Functionally equivalent to 74F543
s Back-to-back registers for storage
s Bidirectional data path
s A and B outputs have current sourcing capability of
15 mA and current sinking capability of 64 mA
s Separate controls for data flow in each direction
s Guaranteed pin-to-pin skew
s Guaranteed 4000V minimum ESD protection
