Procurement Notes

Verify the specific package type and revision status before procurement, as manufacturing updates may occur. Confirm that the 48-SSOP package aligns with your PCB footprint requirements. Ensure compatibility with your system's voltage levels, specifically checking the 1.65 V to 3.6 V operating range. Review the latest datasheet for any changes in electrical characteristics or recommended operating conditions to guarantee proper integration into your design.

Selection Notes

Select this component when designing systems requiring 16-bit data transfer with low power consumption and high speed. It is suitable for applications needing operation below 3.3 V, such as portable electronics or advanced communication interfaces. Consider the ±24 mA drive strength for driving moderate capacitive loads on bus lines. The wide voltage range allows flexibility in interfacing with various logic families within the specified limits.

Part Context

This part belongs to the Texas Instruments Widebus family, which focuses on high-density, high-performance bus solutions. The SN74ALVCH series is engineered for low-voltage applications, offering improved switching speeds and reduced power dissipation compared to older technologies. The DL suffix indicates a 48-pin Shrink Small Outline Package (SSOP), providing a compact form factor suitable for space-constrained designs.

Replacement Considerations

Direct substitutes include other members of the SN74ALVCH16xxx series with compatible pinouts and electrical specifications. Verify that alternative parts maintain the same 1.65 V to 3.6 V operating range and 48-SSOP package dimensions. Ensure that the replacement offers equivalent propagation delay and output drive current to maintain system timing and signal integrity.
