54FCT373TDB

Overview

The 54FCT373TDB is an octal transparent latch manufactured by Renesas Electronics Corporation. It features a single circuit with eight-bit data width and tri-state outputs. The device operates within a supply voltage range of 4.5V to 5.5V and exhibits a propagation delay of 15ns. It is designed for through-hole mounting in a 20-CDIP package measuring 0.300 inches (7.62mm). The component supports an extended operating temperature range from -55°C to +125°C.

Feature Summary

• Provides octal data storage via D-type transparent latch architecture
• Features high-drive tri-state outputs for bus interfacing
• Supports industrial temperature operation up to 125°C

Applications

• Data buffering in digital logic systems
• Interface between microprocessors and peripheral devices
• Temporary data storage in memory architectures

Procurement Notes

Verify the current lifecycle status, as this component may be discontinued or subject to production changes. Confirm RoHS compliance requirements against specific project standards, noting that some variants may not meet current environmental directives. Validate package dimensions and pinout compatibility during integration planning.

Selection Notes

Select this component when an octal latch with tri-state capability is required for through-hole applications. Ensure the design accommodates the 4.5V to 5.5V supply voltage range. Consider the 15ns propagation delay for timing constraints. Verify that the 20-CDIP package fits the available PCB real estate and thermal management strategy.

Part Context

This part belongs to the FCT logic family, which utilizes advanced CMOS technology for high-speed performance. The 54FCT373 series provides reliable data latching functions compatible with standard logic interfaces. The TDB suffix indicates the specific ceramic dual in-line package configuration suitable for robust industrial environments.

Replacement Considerations

Check for official replacement notices or product change notifications from Renesas. Verify if alternative packages or updated versions are available for continued supply.
