3-STATE Octal D-Type Latch •

3-STATE Octal D-Type Flip-Flop

General Description

Features

■ TTL input characteristic compatible

The

MM74HCT373

octal

D-type

latches

and

MM74HCT374 Octal D-type flip flops 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 & pin-out com-

patible. 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.

■ Typical propagation delay: 20 ns

■ Low input current: 1 A maximum

■ Low quiescent current: 80 A maximum

■ Compatible with bus-oriented systems

■ Output drive capability: 15 LS-TTL loads

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.

The MM74HCT374 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

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.

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.
