MM74HCT373MTCX

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

General Description

The MM74HCT373 octal D-type latches and

MM74HCT374 Octal D-type flip flops advanced silicongate CMOS technology, which provides the inherent benefits of low power consumptioand 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 damage due to static discharge by internal diodes to VCC and

ground.

Whethe MM74HCT373 LATCH ENABLE input is HIGH,

the Q outputs will follow the D inputs. Whethe LATCH

ENABLE goes LOW, data at the D inputs will be retained at

the outputs until LATCH ENABLE returns HIGH again.

Whea 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.

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 opositive

going transitions of the CLOCK (CK) input. Whea 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 betweeTTL

and NMOS components and standard CMOS devices.

These parts are also plug ireplacements for LS-TTL

devices and cabe used to reduce power consumptioin

existing designs.
