54FCT16244TEB

Overview

The 54FCT16244TEB is a military-grade, single-supply Fast CMOS octal buffer and line driver manufactured by Renesas Electronics. It features true TTL input and output compatibility with high drive outputs capable of sourcing -15mA and sinking 64mA. The device operates within a temperature range of -55°C to +125°C and supports power-off disable functionality for live insertion applications. Packaged in a 48-lead Thin Small Outline Package (TSOP), it meets MIL-STD-883 Class B standards.

Feature Summary

• Military-grade construction compliant with MIL-STD-883 Class B specifications
• True TTL input and output compatibility ensuring signal integrity across logic families
• High-drive output capability designed for memory, address, and clock drivers
• Power-off disable feature enabling safe live insertion into active systems

Applications

• Memory and address bus drivers
• Clock distribution networks
• Bus-oriented transmitter/receiver circuits
• Live insertion systems requiring hot-swapping capabilities

Procurement Notes

Verify the specific suffix 'TEB' against official Renesas documentation to confirm package type and tape-and-reel specifications. Ensure procurement channels provide traceability certificates required for military-grade components. Confirm RoHS status as military parts may differ from commercial equivalents. Validate that the supplier can provide full lot traceability and material declarations consistent with defense industry requirements.

Selection Notes

Select this component when designing systems requiring robust performance in extreme environmental conditions. It is suitable for applications demanding high current drive capabilities and strict timing reliability. Consider this part over commercial variants if MIL-STD-883 compliance is mandatory. Evaluate the TSOP-48 footprint constraints against available board space. Verify voltage levels match the system's 5V supply requirements.

Part Context

This component belongs to the FCT (Fast CMOS) family, bridging the performance gap between standard CMOS and Schottky TTL technologies. It offers improved board density and faster switching speeds compared to legacy counterparts. The 54-series designation indicates its qualification for extended temperature ranges and enhanced reliability standards typical of aerospace and defense electronics.

Replacement Considerations

The 74FCT240T serves as the commercial equivalent for non-military applications. For direct replacements, verify pinout compatibility and electrical characteristics. Ensure substitute parts meet the same MIL-STD-883 Class B requirements if operating in harsh environments. Cross-reference datasheets for drive strength and propagation delay differences.
