54FCT373CTDB

Overview

The 54FCT373CTDB 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 dimensions of 0.300 inches (7.62mm). The component functions reliably across an extended industrial temperature range from -55°C to +125°C.

Feature Summary

• Provides octal data storage via D-type transparent latch architecture
• Features high-drive three-state outputs for bus interfacing
• Supports wide operating temperature range for industrial environments

Applications

• Parallel data buffering in digital systems
• Bus interface circuits requiring latched data retention
• Industrial control logic applications

Procurement Notes

Verify the specific suffix CTDB against official Renesas documentation to confirm pinout compatibility and package integrity. Confirm RoHS status as historical records indicate non-compliance for this variant. Check for End-of-Life notifications or Product Change Notices prior to procurement to ensure long-term availability and manufacturing consistency.

Selection Notes

Select this component when a through-hole octal latch with three-state outputs is required for legacy or industrial designs. Ensure the design accommodates the 20-CDIP package footprint and meets the 4.5V to 5.5V power supply requirements. Consider the 15ns propagation delay for timing analysis in the target application circuit.

Part Context

This part belongs to the FCT logic family, which combines Fast CMOS speed with TTL-compatible inputs. The 54FCT series is typically designed for military-grade reliability, indicated by the '54' prefix, supporting the wider temperature range compared to commercial variants. It serves as a standard solution for parallel data storage in robust electronic systems.

Replacement Considerations

Official substitutes include the IDT54FCT373CTDB. Verify functional equivalence and package compatibility before substitution.
