74FCT162244ATPAG8

Overview

The 74FCT162244ATPAG8 is a 16-bit buffer and line driver manufactured by Renesas Electronics Corporation. It belongs to the FCT logic series and features non-inverting polarity with four-channel architecture, providing four inputs and four outputs per channel. The device utilizes a 48-TSSOP surface-mount package and operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical specifications include a propagation delay of 4.8 ns, high-level output current of -24 mA, low-level output current of 24 mA, and static current of 10 uA. It supports three-state outputs and functions across an operating temperature range from -40°C to +85°C.

Feature Summary

• Provides 16-bit buffering capability through four independent channels for signal integrity maintenance.
• Features three-state outputs allowing multiple drivers to share bus lines without interference.
• Utilizes FCT CMOS technology to achieve fast switching speeds with low power consumption.

Applications

• High-speed data bus buffering in computer systems
• Clock distribution networks requiring precise timing control
• Memory interface circuits for address and data lines

Procurement Notes

Verify component authenticity due to end-of-life status. Confirm RoHS compliance details as specified in official documentation. Check for moisture sensitivity level requirements during storage and handling. Ensure replacement parts meet identical pinout and electrical specifications. Validate supplier authorization for discontinued semiconductor inventory.

Selection Notes

Select this component when designing systems requiring 16-bit wide data paths with high-speed performance. The FCT series offers superior speed compared to standard TTL while maintaining CMOS power efficiency. Consider the 48-pin TSSOP package constraints for PCB layout. Verify that the 5V supply rail matches system requirements. Evaluate thermal management needs given the operating temperature range.

Part Context

This part is part of the 74FCT162244T family of buffers and line drivers. It serves as a critical interface component in digital logic designs where signal isolation and drive strength are necessary. The device replaces older discrete logic solutions by integrating multiple gates into a single IC, reducing board space and assembly complexity.

Replacement Considerations
