Octal D-Type Latch with TRI-STATEÉ Outputs
General Description
The ’F573isa high speed octal latch with buffered common
Latch Enable (LE) and buffered common Output Enable
(OE) inputs.
This deviceis functionally identicaltothe ’F373buthas
different pinouts.
Features Inputs and outputson opposite sidesof package
allowing easy interface with microprocessors Usefulas inputor output portfor microprocessors Functionally identicalto ’F373 TRI-STATE outputsforbus interfacing Guaranteed 4000V minimum ESD protection
