Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.

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 the 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.
The MC74AC374/74ACT374 consists of eight edge−
