74ALVTH16240DLG4

Overview

The SN74ALVTH16240DLG4 is a 16-bit buffer and line driver manufactured by Texas Instruments. It features three-state outputs and operates within a supply voltage range of 2.7 V to 3.6 V. The device utilizes an SSOP-48 package and supports bidirectional data transmission with low input current characteristics. It is designed for high-speed applications requiring robust signal integrity across the specified voltage domain.

Feature Summary

• Provides 16-bit buffering and driving capabilities with three-state output control
• Operates reliably within a 2.7 V to 3.6 V power supply range
• Features low input current design to minimize loading on upstream drivers

Applications

• High-speed data bus buffering in embedded systems
• Voltage level translation between 3.3 V logic domains
• Bidirectional data flow management in memory interfaces

Procurement Notes

Verify the exact suffix 'DLG4' against the manufacturer's official datasheet to confirm the specific package variant and tape-and-reel configuration. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the ordering part number with the latest TI product selection guide to avoid obsolete or alternate pinout versions.

Selection Notes

Select this component when a 16-bit wide buffer with three-state capability is required for 3.3 V logic systems. Consider the SSOP-48 package constraints regarding board space and thermal dissipation. Evaluate propagation delay specifications against system timing requirements to ensure signal integrity at target clock frequencies.

Part Context

This component belongs to the ALVTH (Advanced Low-Voltage CMOS Technology High-Speed) family from Texas Instruments. The series is engineered for high-speed digital applications, offering improved performance over standard LVTH devices while maintaining compatibility with 3.3 V power supplies. It serves as a critical interface element in modern digital circuit designs.

Replacement Considerations

Direct replacements include the SN74ALVTH16240DGGR, which shares identical electrical characteristics but utilizes a TSSOP-48 package instead of SSOP-48. Verify pin-to-pin compatibility and package dimensions before substitution to ensure mechanical fit within the existing PCB layout.
