74FCT373CTSOG8

Latches Overview

The Renesas 74FCT373CTSOG8 is an octal transparent D-type latch integrated circuit belonging to the 74FCT logic series. It features eight independent D-type latches with three-state outputs, housed in a 20-pin SOIC package. The device operates within a supply voltage range of 4.75V to 5.25V and supports a working temperature range from -40°C to +85°C. It provides high-speed data storage capabilities suitable for digital systems requiring temporary data retention.

Latches Feature Summary

• Octal transparent D-type latch architecture providing eight independent data storage channels
• Three-state output capability allowing direct connection to system buses without external buffers
• Wide operating temperature range supporting industrial and commercial applications
• Compatible with standard TTL input levels for seamless integration with legacy logic families

Latches Applications

• Temporary data storage in high-speed digital processing circuits

Latches Procurement Notes

This component has been officially discontinued by Renesas Electronics Corporation, with end-of-life notifications confirmed via PCN dated January 3, 2024. Procurement must focus on identifying verified replacement parts or alternative manufacturers offering equivalent functionality. Verify that any substitute component matches the original pinout, electrical specifications, and package dimensions to ensure compatibility with existing designs.

Latches Selection Notes

Designers should evaluate replacement options based on functional equivalence rather than exact part number matching. Key selection criteria include maintaining the octal latch configuration, three-state output characteristics, and 5V operation requirements. Ensure the substitute component supports the required temperature range and package type to avoid mechanical redesigns while confirming availability through authorized distribution channels.

Latches Part Context

The 74FCT373CTSOG8 belongs to the widely adopted 74FCT family, known for combining CMOS low power consumption with TTL-compatible speed and drive capabilities. This specific variant represents an octal latch solution designed for high-density applications. As a discontinued product, it reflects historical design choices in mixed-signal systems where reliable data latching was critical for system stability and performance optimization.

Latches Replacement Considerations

Publicly confirmed substitutes include Texas Instruments CY74FCT573CTSOC and CY74FCT2573CTSOC. These alternatives offer comparable latch functionality and should be evaluated for pin-to-pin compatibility and electrical parameter alignment before implementation.
