SN74ALVCH16282DGR

Overview

The SN74ALVCH16282DGR is a 18-bit universal bus exchanger from Texas Instruments, belonging to the ALVC/VCX/A series. It operates within a supply voltage range of 1.65 V to 3.6 V and features CMOS logic technology. The device supports surface-mount installation in a TSSOP-48 package and functions across an extended temperature range of -40°C to +85°C. Designed for high-speed data routing, it provides true output configuration with equivalent series resistors on output ports, eliminating the need for external components.

Feature Summary

• Functions as an 18-bit universal bus exchanger for flexible data routing
• Integrated output port series resistors remove requirement for external components
• Supports wide operating voltage range from 1.65 V to 3.6 V

Applications

• High-speed data bus interconnects
• System-level data routing architectures
• Universal bus exchange applications

Procurement Notes

Verify the specific package suffix 'DGR' corresponds to the TSSOP-48 reel packaging configuration required for your assembly process. Confirm that the ALVC logic family voltage levels align with your system's I/O requirements. Ensure thermal management strategies account for the specified operating temperature range during final product integration.

Selection Notes

Select this component when an 18-bit bidirectional or unidirectional bus exchange capability is required within low-voltage systems. The integrated series resistors simplify PCB layout by reducing component count. Consider the TSSOP-48 footprint constraints and ensure compatibility with automated pick-and-place equipment specifications for reel-fed manufacturing.

Part Context

This part belongs to Texas Instruments' Widebus family, designed for complex digital systems requiring efficient data path management. As an ALVC device, it offers performance characteristics suitable for modern embedded applications. The DGR suffix indicates a tape-and-reel packaging format optimized for high-volume surface-mount production lines.

Replacement Considerations

Direct substitutes include other 18-bit bus exchangers from the same ALVC family, such as the SN74ALVCH16282DL. Verify pinout compatibility and electrical parameters before swapping packages. Alternative manufacturers may offer functionally similar parts, but require thorough validation of timing and voltage specifications.
