MM74HCT573 • MM74HCT574

Octal D-Type Latch • 3-STATE Octal D-Type Flip-Flop

going transitions of the Clock (CK) input. When a high logic

level is applied to the Output Control (OC) input, all outputs

go to a high impedance state, regardless of what signals

are present at the other inputs and the state of the storage

elements.

General Description

The

MM74HCT573

octal

D-type

latches

and

MM74HCT574 octal D-type flip-flop advanced silicon-gate

CMOS technology, which provides the inherent benefits of

low power consumption and wide power supply range, but

are LS-TTL input and output characteristic and pin-out

compatible. The 3-STATE outputs are capable of driving 15

LS-TTL loads. All inputs are protected from damage due to

static discharge by internal diodes to V_CCand ground.

The MM74HCT devices are intended to interface between

TTL and NMOS components and standard CMOS devices.

These parts are also plug in replacements for LS-TTL

devices and can be used to reduce power consumption in

existing designs.

When the MM74HCT573 Latch Enable input is HIGH, the

Q outputs will follow the D inputs. When the Latch Enable

goes LOW, data at the D inputs will be retained at the out-

puts until Latch Enable returns HIGH again. When a high

logic level is applied to the Output Control input, all outputs

go to a high impedance state, regardless of what signals

are present at the other inputs and the state of the storage

elements.

Features

■ TTL input characteristic compatible

■ Typical propagation delay: 18 ns

■ Low input current: 1 µA maximum

■ Low quiescent current: 80 µA maximum

■ Compatible with bus-oriented systems

■ Output drive capability: 15 LS-TTL loads

The MM74HCT574 are positive edge triggered flip-flops.

Data at the D inputs, meeting the setup and hold time

requirements, are transferred to the Q outputs on positive
