OCTAL D-TYPE
FLIP-FLOP WITH
3-STATE OUTPUTS
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
Clock (CP) transition.
The MC74AC574/74ACT574 is functionally identical to the MC74AC374/
74ACT374 except for the pinouts.
• Inputs and Outputs on Opposite Sides of Package
Allowing Easy Interface with Microprocessors
• Useful as Input or Output Port for Microprocessors
• Functionally Identical to MC74AC374/74ACT374
• 3-State Outputs for Bus-Oriented Applications
• Outputs Source/Sink 24 mA

FUNCTIONAL DESCRIPTION
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
timerequirements 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.
