MC74ACT564
Octal D−Type Flip−Flop
with 3−State Outputs
The MC74ACT564 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 MC74ACT564 device is functionally indentical to the
MC74ACT574, but with inverted outputs.

FUNCTIONAL DESCRIPTION
The MC74ACT564 consists of eight edge−triggered
flip−flops with individual D−type inputs and 3−state
complementary 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 times 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.
