The MC74AC574/74ACT574 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
http://onsemi.com
Clock (CP) transition.
The MC74AC574/74ACT574 is functionally identical to the
MC74AC374/74ACT374 except for the pinouts.

FUNCTIONAL DESCRIPTION
H

NC
NC
NC
NC
The MC74AC574/74ACT574 consists of eight edge-
triggered flip–flops with individual D–type inputs and
3–state true outputs. The buffered clock and buffered Output
Enable are common to all flip–flops. The eight flip–flops
will store the state of their individual D inputs that meet the
setup and hold time requirements on the LOW–to–HIGH
Clock (CP) transition. With the Output Enable (OE) LOW,
the contents of the eight flip–flops are available at the
outputs. When OE is HIGH, the outputs go to the high
impedance state. Operation of the OE input does not affect
the state of the flip–flops.

L = LOW Voltage Level
