General Description
The AC/ACT374 is a high-speed, low-power octal D-type
flip-flop featuring separate D-type inputs for each flip-flop
and 3-STATE outputs for bus-oriented applications. A
buffered Clock (CP) and Output Enable (OE
) are com-
mon to all flip-flops.
Ordering Information
Device also available in Tape and Reel. Specify by appending suffix letter “X” to the ordering number.
All packages are lead free per JEDEC: J-STD-020B standard.

74AC374, 74ACT374 — Octal D-Type Flip-Flop with 3-STATE Outputs
Connection Diagram
Pin Description
Functional Description
The AC/ACT374 consists of eight edge-triggered flip-
flops with individual D-type inputs and 3-STATE true out-
puts. 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 con-
tents of the eight flip-flops are available at the outputs.
When the OE
is HIGH, the outputs go to the high imped-
ance state. Operation of the OE
input does not affect the
state of the flip-flops.
