TRI-STATE Octal D-Type Latch

MM54HCT574/MM74HCT574

TRI-STATE Octal D-Type Flip-Flop

General Description

The MM54HCT573/MM74HCT573 octal D-type latches and

MM54HCT574/MM74HCT574 Octal D-type flip flops ad-

vanced 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

& pin-out compatible. The TRI-STATE outputs are capable

of driving 15 LS-TTL loads. All inputs are protected from

positive 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.

MM54HCT/MM74HCT devices are intended to interface be-

tween 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.

damage due to static discharge by internal diodes to V

and ground.

When the MM54HCT573/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 outputs 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 mA maximum

Low quiescent current: 80 mA maximum

Compatible with bus-oriented systems

The MM54HCT574/MM74HCT574 are positive edge trig-

gered flip-flops. Data at the D inputs, meeting the setup and

hold time requirements, are transferred to the Q outputs on

Output drive capability: 15 LS-TTL loads
