MM74HC373WM

Latches Overview

The MM74HC373WM is an octal D-type transparent latch manufactured by Fairchild Semiconductor, now part of onsemi. It utilizes advanced silicon-gate CMOS technology to provide high-speed data storage with low power consumption and high noise immunity. The device features eight D-type latches with three-state outputs, allowing direct interface with bus lines in bus-organized systems. It operates within a supply voltage range of 2V to 6V and supports a wide operating temperature range from -40°C to 85°C. The component is housed in a 20-SOIC surface-mount package.

Latches Feature Summary

• Transparent latch operation allows Q outputs to follow D inputs when the Latch Enable input is HIGH, retaining data when LOW.
• Three-state output capability enables direct connection to system buses without additional drivers.
• High noise immunity and low power dissipation characteristic of standard CMOS integrated circuits.
• Internal diode clamps protect all inputs from damage due to static discharge.

Latches Applications

• Interfacing with bus lines in bus-organized systems
• Data storage applications requiring transparent latch functionality
• Driving LS-TTL loads

Latches Procurement Notes

Verify the manufacturer designation carefully, as Fairchild Semiconductor's logic products are now produced under the onsemi brand. Confirm the specific suffix 'WM' corresponds to the 20-SOIC package and tube packaging format. Ensure the datasheet version matches the required electrical specifications for your design constraints.

Latches Selection Notes

Select this component when an octal latch with transparent mode and three-state outputs is required. It is compatible with the 74LS logic family in terms of speed, function, and pin-out. Consider the 2V to 6V supply voltage range and ensure the 20-SOIC package fits the PCB layout requirements.

Latches Part Context

This component belongs to the 74HC series of high-speed CMOS logic devices. It is functionally related to other octal latches like the 74HC374, though the latter uses clocked flip-flops rather than transparent latches. The MM prefix typically denotes a military or extended grade variant in some contexts, but generally indicates the specific Fairchild/onsemi product line.
