54F 74F574
Octal D-Type Flip-Flop with TRI-STATE Outputs
General Description
The ’F574 is a high-speed low power octal flip-flop with a
buffered common Clock (CP) and a buffered common Out-
put Enable (OE) The information presented to the D inputs
is stored in the flip-flops on the LOW-to-HIGH Clock (CP)
transition
This device is functionally identical to the ’F374 except for
the pinouts
Features
Y Inputs and outputs on opposite sides of package
allowing easy interface with microprocessors
Y Useful as input or output port for microprocessors
Y Functionally identical to ’F374
Y TRI-STATE outputs for bus-oriented applications
