General Description
The 鈥橝C/鈥橝CT574 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 in-
puts is stored in the flip-flops on the LOW-to-HIGH Clock
(CP) transition.
The 鈥橝C/鈥橝CT574 is functionally identical to the 鈥橝C/鈥橝CT374
except for the pinouts.
