54FCT162244CTEB

Overview

The IDT 54FCT162244CTEB is a high-speed, low-power CMOS bus driver belonging to the FCT series. It features two independent bidirectional data paths, each handling eight bits of data. The device operates with a nominal supply voltage of 5 V and provides three-state outputs for effective bus management. It utilizes positive edge triggering for data synchronization. The component is housed in a CPACK-56 package, specifically identified as FL56,.4,25, containing 56 terminals. It supports surface mount technology and offers a propagation delay of approximately 6.3 ns at nominal supply conditions.

Feature Summary

• Provides dual bidirectional data transfer capabilities with independent control for each 8-bit path
• Features three-state outputs to facilitate efficient multi-driver bus architectures
• Utilizes positive edge triggering for precise data synchronization during transmission

Applications

• High-speed memory interface data buffering
• Clock distribution network drivers
• Bus-oriented transmit-receive input applications

Procurement Notes

Verify the specific suffix CTEB against the manufacturer's current datasheet to confirm pinout compatibility and package dimensions. Ensure the procurement source provides documentation confirming the ceramic glass-sealed construction and MIL-STD-883 screening levels if required for your application. Cross-reference the JESD-30 code R-XDFP-F56 to validate the physical footprint matches your PCB design constraints.

Selection Notes

Select this component when designing systems requiring robust bidirectional data flow between microprocessors and peripheral devices. The FCT series offers a performance balance suitable for replacing older ABT logic functions. Consider the 56-pin CPACK package size relative to available board space. Verify that the 5 V operating voltage aligns with the rest of the system's power rails and that the 125 °C maximum operating temperature meets environmental requirements.

Part Context

This part belongs to the Integrated Device Technology FCT (Fast CMOS) family, designed as a high-speed replacement for earlier transistor-transistor logic families. The 54FCT designation indicates military-grade temperature range capability (-55 °C to 125 °C). The 162244 variant specifically denotes a dual 8-bit bus driver configuration within this lineage, sharing architectural similarities with other FCT buffer and transceiver components.
