MC74HCT373ADWG

Latches Overview

The MC74HCT373ADWG is an octal D-type transparent latch manufactured by onsemi, belonging to the HCT logic series. It features eight independent D-type latches with three-state outputs in a 20-pin SOIC package. The device operates within a supply voltage range of 4.5V to 5.5V and supports propagation delays of 28ns. It is designed for surface-mount installation and functions reliably across an extended temperature range from -55°C to +125°C.

Latches Feature Summary

• Octal configuration providing eight independent transparent latching channels
• Three-state output capability allowing direct bus system interfacing
• HCT logic compatibility ensuring TTL/NMOS conversion performance

Latches Applications

• Parallel data storage in digital systems
• Bus-oriented memory applications
• Register operations in computing architectures

Latches Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status as historical records indicate potential variations. Ensure the specific suffix matches required packaging and moisture sensitivity levels. Cross-reference datasheet revisions to validate electrical characteristics against current design requirements before integration.

Latches Selection Notes

Select this component when designing systems requiring parallel data retention with high-speed interface capabilities. The HCT series ensures compatibility with standard TTL logic families while offering CMOS power efficiency. Consider the SOIC-20 footprint for PCB layout constraints and verify thermal management needs given the wide operating temperature range specified for industrial applications.

Latches Part Context

This part belongs to the widely adopted 74HCT family of integrated circuits, known for bridging CMOS and TTL logic standards. The MC74HCT373 variant specifically provides octal latching functionality, distinguishing it from flip-flop counterparts like the 374 series which utilize edge-triggering rather than transparency. It serves as a fundamental building block for sequential logic designs in consumer and industrial electronics.

Latches Replacement Considerations

Direct substitutes include CD74HCT373E from Texas Instruments. Similar alternatives encompass MM74HCT373WMX and SN74HCT373N. Verify pinout compatibility and electrical specifications before substituting to ensure circuit integrity.
