General Description
The ’F574isa high-speed,low power octal flip-flop witha
buffered common Clock (CP)anda buffered common Out-
put Enable (OE).The information presentedtotheD inputs storedinthe flip-flopsonthe LOW-to-HIGH Clock (CP)
transition.
This deviceis functionally identicaltothe ’F374 exceptfor
the pinouts.
Features Inputs and outputson opposite sidesof package
allowing easy interface with microprocessors Usefulas inputor output portfor microprocessors Functionally identicalto ’F374 TRI-STATE outputsfor bus-oriented applications
