74F574 Octal D-Type Flip-Flop with 3-STATE Outputs
General Description
The 74F574 is a high-speed, low power octal flip-flop with a buffered common Clock (CP) and a buffered common Output 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 74F374 except for the pinouts.
Features
s Inputs and outputs on opposite sides of package allowing easy interface with microprocessors s Useful as input or output port for microprocessors s Functionally identical to 74F374 s 3-STATE outputs for bus-oriented applications
