74F564
Octal D-Type Flip-Flop with 3-STATE Outputs
General Description
The 74F564 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 sorted in the flip-flops on the LOW-to-HIGH Clock (CP)
transition.
This device is functionally identical to the 74F574, but has
inverted outputs.
Features
s Inputs and outputs on opposite sides of package allow
easy interface with microprocessors
s Useful as input or output port for microprocessors
s Functionally identical to 74F574
s 3-STATE outputs for bus-oriented applications
