Revised March 2000
DM74LS574
Octal D-Type Flip-Flop with 3-STATE Outputs
General Description
The DM74LS574 is a high speed low power octal flip-flop
with a buffered common Clock (CP) and a buffered com-
mon 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 DM74LS374
except for the pinouts.
