requirements, are transferred to the Q outputs on 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.

General Description

The

MM74HCT373

octal

D-type

latches

and

MM74HCT374 Octal D-type flip flops advanced silicon-

gate CMOS technology, which provides the inherent bene-

fits of low power consumption and wide power supply

range, but are LS-TTL input and output characteristic &

pin-out compatible. The 3-STATE outputs are capable of

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

age due to static discharge by internal diodes to V_CCand

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.

ground.

When the MM74HCT373 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 CON-

TROL 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: 20 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 MM74HCT374 are positive edge triggered flip-flops.
