3-STATE Octal D-Type Latch

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

storage elements.

General Description

The MM74HC373 high speed octal D-type latches utilize

advanced silicon-gate CMOS technology. They possess

the high noise immunity and low power consumption of

standard CMOS integrated circuits, as well as the ability to

drive 15 LS-TTL loads. Due to the large output drive capa-

bility and the 3-STATE feature, these devices are ideally

suited for interfacing with bus lines in a bus organized sys-

tem.

The 74HC logic family is speed, function, and pin-out com-

patible with the standard 74LS logic family. All inputs are

protected from damage due to static discharge by internal

diode clamps to V_CCand ground.

Features

■ Typical propagation delay: 18 ns

When the 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

■ Wide operating voltage range: 2 to 6 volts

■ Low input current: 1 µA maximum

■ Low quiescent current: 80 µA maximum (74 Series)

■ Output drive capability: 15 LS-TTL loads
