SN74LVTH16501DLG4

Overview

The SN74LVTH16501DLG4 is an 18-bit universal bus transceiver from Texas Instruments, operating within a 2.7V to 3.6V supply voltage range. It features three-state outputs and supports bidirectional data transfer between two buses. The device utilizes ABT technology to ensure low power consumption while maintaining high-speed performance. Designed for surface-mount applications, it offers robust ESD protection and is suitable for demanding digital logic environments requiring reliable data transmission.

Feature Summary

• Supports bidirectional data transfer across 18 bits
• Features three-state outputs for bus isolation
• Operates with low power consumption via ABT technology
• Provides robust electrostatic discharge (ESD) protection

Applications

• High-density data bus systems
• Memory interface circuits
• Portable electronic devices
• Industrial control systems

Procurement Notes

Verify the specific suffix 'LG4' against official Texas Instruments documentation to confirm package type and RoHS compliance status. Ensure compatibility with existing PCB footprints and soldering profiles. Cross-reference ordering information with authorized distributors to avoid counterfeit components. Confirm availability and lead times through official channels prior to procurement planning.

Selection Notes

Select this component when an 18-bit wide bus interface is required with low power dissipation. The 2.7V to 3.6V operating range makes it suitable for 3.3V logic systems. Consider the SSOP or similar surface-mount package options if space constraints exist. Evaluate ESD protection requirements and compare propagation delays against system timing specifications before finalizing the design.

Part Context

This part belongs to the SN74LVTH series of universal bus transceivers. It shares functional similarities with other 18-bit transceivers but is distinguished by its specific voltage range and output drive capabilities. The LVTH designation indicates Low Voltage CMOS Technology with Hysteresis, optimized for high-speed operation in low-voltage applications.

Replacement Considerations

Check for direct pin-to-pin replacements such as the SN74LVTH16501DGGR or SN74LVTH16501DLR. Verify electrical characteristics and package dimensions match the original design requirements. Consult Texas Instruments substitution guides for recommended alternatives if the exact part number is unavailable.
