MC74HC373AFR1

Latches Overview

The MC74HC373AFR1 is an octal transparent D-type latch manufactured by onsemi. It features eight D-type latches with three-state outputs, housed in a 20-lead SOIC package. 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. Propagation delay is specified at 21ns, with high and low output currents rated at 7.8mA each. It complies with RoHS3 standards and has a Moisture Sensitivity Level (MSL) of 3.

Latches Feature Summary

• Octal transparent D-type latch architecture providing data storage capability for eight channels
• Three-state outputs allowing direct connection to bus structures without external buffers
• Wide operating temperature range suitable for demanding industrial environments

Latches Applications

• Parallel-to-serial conversion circuits
• Bus-oriented memory mapping
• Register files in microprocessor systems

Latches Procurement Notes

Verify the specific suffix 'FR1' against the official onsemi datasheet to confirm tape-and-reel packaging specifications. Ensure the ordering part number matches the exact package width and lead finish requirements for your PCB assembly process. Cross-reference the MSL rating with your facility's floor life management protocols before soldering.

Latches Selection Notes

Select this component when an octal latch with three-state outputs is required for bus interfacing. The HC series offers CMOS compatibility with standard TTL logic levels. Consider the 20-SOIC package dimensions and the extended temperature range if the application involves harsh environmental conditions or high thermal loads.

Latches Part Context

This part belongs to the 74HC family of high-speed CMOS logic devices. It is functionally equivalent to other octal transparent latches in the industry but is specifically identified by the onsemi manufacturer code. The 'A' prefix typically denotes an advanced version or specific manufacturing lot characteristics defined by the vendor.

Latches Replacement Considerations

Direct substitutes include MM74HC373MTC and SN74HC373AN, provided pinouts and electrical characteristics are verified. Ensure any replacement maintains the same three-state output functionality and voltage range compatibility.
