FUNCTIONAL DESCRIPTION
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
The MC74ACT564 consists of eight edge−triggered

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.
