74FCT16244ATPAG8

Overview

The Renesas Electronics Corporation 74FCT16244ATPAG8 is a 16-bit buffer and line driver belonging to the FCT logic series. It features four input lines and four output lines with non-inverting polarity. The device operates within a supply voltage range of 4.5 V to 5.5 V, drawing a maximum static current of 5 uA and a working power supply current of 6.4 mA. It provides high-level output currents up to -32 mA and low-level output currents up to 64 mA. The component exhibits a propagation delay of 1.5 ns and functions reliably across an operating temperature range from -40 C to +85 C.

Feature Summary

• Provides 16-bit buffering and line driving capabilities via four independent channels.
• Features three-state outputs for effective bus management and isolation.
• Supports non-inverting signal transmission with defined drive strengths.

Applications

• High-speed data bus buffering in computing systems
• Line driving for parallel interface connections
• Signal distribution in mixed-signal environments

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status and specific package markings against official datasheets. Check for end-of-life notices or obsolescence warnings prior to procurement decisions. Ensure storage conditions align with moisture sensitivity level requirements to maintain device integrity during assembly processes.

Selection Notes

Select this component when 16-bit buffering with fast propagation delays is required within a 5V logic environment. Consider the TSSOP-48 package dimensions for PCB layout compatibility. Evaluate the 32 mA high-level and 64 mA low-level drive capabilities against load requirements. Verify that the 4.5 V to 5.5 V supply range matches the system power architecture.
