54FCT373ATLB

Overview

The 54FCT373ATLB is an octal transparent latch manufactured by Renesas Electronics Corporation. It features a single circuit with eight-bit data width and three-state outputs. The device operates within a supply voltage range of 4.5V to 5.5V and supports a propagation delay of 15ns. It is designed for through-hole mounting in a 20-CDIP package with a lead pitch of 0.300 inches (7.62mm). The component functions reliably across an industrial temperature range from -55°C to +125°C.

Feature Summary

• Provides transparent latching functionality for eight-bit data paths
• Features high-drive three-state outputs for bus interfacing
• Supports wide operating temperature ranges for industrial applications

Applications

• Data storage in digital logic systems
• Bus interface buffering
• Parallel data transfer control

Procurement Notes

Verify the specific suffix 'TLB' against official manufacturer documentation to confirm pinout compatibility and package dimensions, as variations exist within the FCT series. Confirm RoHS compliance status and current lifecycle stage directly with the supplier or manufacturer, as this component may be subject to discontinuation notices or production changes.

Selection Notes

Select this component when an octal transparent latch with three-state outputs is required for through-hole assembly. Ensure the design accommodates the 20-CDIP footprint and meets the 4.5V to 5.5V power supply requirements. Verify that the 15ns propagation delay aligns with system timing constraints and that the operating temperature range covers the intended environmental conditions.

Part Context

This part belongs to the 54FCT373 family of octal transparent latches. It shares functional similarities with other devices in the FCT logic series but is distinguished by its specific package type and suffix designation. The 54FCT373 series is commonly used in legacy and industrial designs requiring robust parallel data handling capabilities.

Replacement Considerations

Consult official substitution guides for equivalent parts such as the 54FCT373TDB or IDT equivalents. Verify electrical parameters and pin compatibility before replacement.
