MM74HCT373WMX

Latches Overview

The MM74HCT373WMX is an octal transparent D-type latch manufactured by Fairchild Semiconductor, part of the 74HCT logic family. It features eight D-type latches with three-state outputs in a 20-pin SOIC package. The device operates on a single 5V supply (4.5V to 5.5V) and provides high noise immunity compatible with TTL inputs. Key electrical characteristics include a propagation delay of 25ns and output drive currents of 7.2mA for both high and low states. It functions within a temperature range of -40°C to +85°C.

Latches Feature Summary

• Octal configuration providing eight independent transparent D-type latches
• Three-state outputs allowing direct bus system interfacing
• CMOS construction ensuring high noise immunity and low power consumption
• TTL-compatible input levels simplifying interface with standard logic

Latches Applications

• Register files for data storage in digital systems
• Bus-oriented memory applications requiring tri-state control
• Parallel-to-serial conversion circuits
• Temporary data holding in microprocessor-based designs

Latches Procurement Notes

Verify the manufacturer designation as Fairchild Semiconductor or its successor entities, as corporate acquisitions may affect branding. Confirm the specific suffix 'WMX' corresponds to the tape-and-reel packaging format required for automated assembly. Ensure the component meets RoHS compliance standards relevant to your manufacturing region before finalizing procurement orders.

Latches Selection Notes

Select this component when an octal latch with three-state capability is required for bus-driven architectures. The HCT series ensures compatibility with 5V CMOS and TTL logic families. Consider the 20-SOIC package dimensions for PCB layout constraints. Verify that the 25ns propagation delay meets the timing requirements of your specific clock frequencies and signal integrity needs.

Latches Part Context

This component belongs to the widely adopted 74HCT logic family, designed for high-speed CMOS operation with TTL-compatible inputs. The MM74HCT373 variant specifically implements an octal transparent latch structure. It serves as a fundamental building block for sequential logic circuits, offering reliable data retention and controlled output driving capabilities in standard industrial and commercial electronic applications.

Latches Replacement Considerations

Equivalent parts from other manufacturers include the SN74HCT373 series from Texas Instruments and the MC74HCT373 from ON Semiconductor. These alternatives share identical logical functionality and pinout configurations. Verify that any substitute maintains the same 20-SOIC package footprint and electrical specifications to ensure seamless integration without redesigning the host circuit board.
