MC74HC373AFELG

Latches Overview

The MC74HC373AFELG is a D-type transparent latch manufactured by onsemi, belonging to the 74HC series. It features eight independent D-type latches with tri-state outputs housed in a 20-SOIC package. The device operates within a supply voltage range of 2V to 6V and supports surface-mount installation. Key electrical parameters include a propagation delay of 21ns and output currents of 7.8mA for both high and low states. It functions across an operating temperature range of -55°C to 125°C.

Latches Feature Summary

• Transparent latch operation allows data to pass directly from input to output when the latch enable signal is active.
• Tri-state outputs facilitate direct connection to bus systems without additional buffering requirements.
• CMOS construction ensures compatibility with LSTTL logic levels while maintaining low power consumption.

Latches Applications

• Parallel-to-serial data conversion circuits
• Bus-oriented memory address latching
• General-purpose register storage applications

Latches Procurement Notes

Verify the specific suffix 'G' against official datasheets to confirm RoHS compliance status and lead-free manufacturing details. Ensure the 20-SOIC package dimensions match the target PCB footprint. Confirm that the 7.8mA drive current meets load requirements. Validate the -55°C to 125°C temperature rating against environmental specifications.

Latches Selection Notes

Select this component for designs requiring eight-bit parallel data storage with bus-compatible outputs. The 74HC series offers speed and power advantages over older TTL families. Consider the 20-SOIC package for surface-mount assembly efficiency. Verify that the 2V to 6V supply range aligns with the system's available voltage rails.

Latches Part Context

This part is a variant of the standard 74HC373 octal D-type latch. The 'MC' prefix typically denotes automotive or extended grade variants from onsemi, though verification is required. It shares functional equivalence with other 74HC373 devices but may differ in packaging or reliability standards. The 'AFELG' suffix indicates specific tape-and-reel packaging and compliance attributes.

Latches Replacement Considerations

Direct substitutes include MC74HC373AFL1 and MC74HC373ADTG from onsemi. Cross-manufacturer equivalents such as Toshiba 74HC373D are functionally similar but require pinout and parameter verification. Always check package width and moisture sensitivity levels before substitution.
