74ACT534

Octal D-Type Flip-Flop with 3-STATE Outputs

General Description

Features

n I_CCand I_OZreduced by 50%

n Edge-triggered D-type inputs

n Buffered positive edge-triggered clock

n 3-STATE outputs for bus-oriented applications

n Outputs source/sink 24 mA

The ACT534 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 common to all

flip-flops. The ACT534 is the same as the ACT374 except

that the outputs are inverted.

n ACT534 has TTL-compatible inputs

n Inverted output version of ACT374

Functional Description

The ACT534 consists of eight edge-triggered flip-flops with

individual D-type inputs and 3-STATE complementary 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

times requirements on the LOW-to-HIGH Clock (CP) transi-

tion. 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.
