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.
