74FCT16244TPACTG4

Overview

The Texas Instruments 74FCT16244TPACTG4 is a 16-bit buffer and line driver belonging to the FCT logic family. It features non-inverting, three-state outputs housed in a 48-pin TSSOP package. The device operates within a supply voltage range of 4.5 V to 5.5 V. Key electrical parameters include a propagation delay of 4.8 ns at 5 V, high-level output current of -24 mA, and low-level output current of 24 mA. Static current is specified at 5 uA, with a maximum operating temperature of +85 C.

Feature Summary

• Provides 16-bit buffering and line driving capabilities for digital signal transmission.
• Features three-state outputs to facilitate bus-oriented architectures and system isolation.
• Utilizes FCT CMOS technology to ensure compatibility with standard TTL logic levels.

Applications

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

Procurement Notes

Verify the specific suffix 'G4' confirms RoHS compliance status as per manufacturer documentation. Confirm the TSSOP-48 package dimensions match your PCB footprint requirements. Check for obsolescence notices or lifecycle status updates from Texas Instruments prior to finalizing design-in decisions.

Selection Notes

Select this component when 16-channel buffering with three-state control is required. Ensure the system operates within the 4.5 V to 5.5 V supply range. Consider the 4.8 ns propagation delay for timing constraints. Verify thermal dissipation capabilities if multiple drivers are active simultaneously.
