MC74HC373AFL1

Latches Overview

The MC74HC373AFL1 is an octal transparent D-type latch manufactured by onsemi, housed in a 20-SOIC surface-mount package. It features eight D-type latches with three-state outputs, designed for bus-oriented systems. The device operates within a supply voltage range of 2V to 6V and supports a wide operating temperature range from -55°C to 125°C. Key electrical characteristics include a propagation delay of 21ns and output currents of 7.8mA for both high and low states. It complies with RoHS3 standards and has a Moisture Sensitivity Level (MSL) of 3.

Latches Feature Summary

• Transparent latch operation allows data to pass directly to outputs when enabled.
• Three-state outputs facilitate direct connection to system buses without external drivers.
• Wide operating temperature range ensures reliability in extreme environmental conditions.
• CMOS input compatibility enables integration with standard logic families.

Latches Applications

• Bus-oriented memory mapping systems
• Address latching in microcontroller interfaces
• Portable battery-powered equipment requiring low power consumption

Latches Procurement Notes

Verify the specific suffix FL1 corresponds to the 20-SOIC bulk packaging configuration as listed in distributor catalogs. Confirm RoHS3 compliance status matches current regulatory requirements for your region. Ensure the operating temperature range of -55°C to 125°C aligns with your thermal design constraints. Check MSL level 3 handling precautions during assembly to prevent moisture damage.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is required for bus isolation. The HC series offers higher speed than LS equivalents while maintaining CMOS power efficiency. The extended temperature range makes it suitable for industrial applications where standard commercial grade parts may fail. Verify that the 20-SOIC package fits your PCB footprint constraints.

Latches Part Context

This part belongs to the 74HC family of high-speed CMOS logic devices. It is functionally similar to other octal latches like the MM74HC373 but differs in package type and manufacturer-specific revisions. The 'A' suffix typically denotes improved specifications or revised manufacturing processes compared to earlier versions. It serves as a fundamental building block for digital data storage and transfer in complex electronic systems.

Latches Replacement Considerations

Direct pin-compatible substitutes include the MM74HC373MTC in TSSOP-20, though package dimensions differ. For SOIC-20 packages, verify equivalent parts from other manufacturers such as Texas Instruments SN74HC373AN, ensuring voltage and temperature ranges match your application needs.
