MC74HCT373ADW

Latches Overview

The MC74HCT373ADW is an octal transparent latch manufactured by onsemi, belonging to the HCT logic series. It features eight 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 up to 45ns. It functions as a level converter between TTL/NMOS inputs and CMOS outputs, ensuring compatibility across mixed-logic systems.

Latches Feature Summary

• Provides eight independent transparent latch channels for data storage
• Features three-state outputs for bus-oriented applications
• Supports HCT logic levels for TTL/NMOS to CMOS conversion
• Operates reliably across extended industrial temperature ranges

Latches Applications

• Bus-oriented memory mapping
• Register files for data storage
• Interface circuits between different logic families
• Parallel data buffering in digital systems

Latches Procurement Notes

Verify the specific suffix 'ADW' against official datasheets to confirm package dimensions and tape-and-reel specifications. Ensure the component meets required RoHS compliance standards for your region. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the operating temperature range aligns with your system's environmental constraints before finalizing procurement.

Latches Selection Notes

Select this component when designing systems requiring octal latching with high-speed performance. The HCT series ensures compatibility with standard TTL logic levels while offering CMOS noise immunity. Consider the 20-pin SOIC package for surface-mount assembly efficiency. Evaluate the three-state output capability if the design requires shared bus architectures or bidirectional data transfer paths.

Latches Part Context

This component is part of the widely adopted 74HCT family, known for bridging HC/HCT logic with legacy TTL interfaces. The MC74HCT373 variant specifically provides octal configuration, distinguishing it from hex or quad latch alternatives. It serves as a fundamental building block for sequential logic circuits in consumer electronics and industrial control applications.

Latches Replacement Considerations

Direct substitutes include CD74HCT373E from Texas Instruments. Verify pinout compatibility and electrical characteristics before substitution.
