SN74ALVCH16271DL

Overview

The SN74ALVCH16271DL is a universal bus function integrated circuit manufactured by Texas Instruments. It operates as a 12-bit to 24-bit multiplexed bus exchanger within the ALVCH logic series. The device supports a supply voltage range of 1.65 V to 3.6 V and features propagation delays of 5.8 ns and 5.1 ns. It is housed in an SSOP-56 package and functions as a single circuit with 24 channels. The component is rated for operation between -40°C and +85°C, providing high-level output current of 24 mA.

Feature Summary

• Multiplexed bus exchange capability supporting variable bit widths from 12 to 24 bits
• Low-voltage operation compatible with 1.65 V to 3.6 V power supplies
• High drive strength with 24 mA output current capability

Applications

• Data routing in embedded systems
• Bus arbitration in computer architectures
• Signal switching in communication interfaces

Procurement Notes

Verify the specific suffix 'DL' corresponds to the SSOP-56 tube packaging configuration when sourcing. Confirm that the manufacturer designation matches Texas Instruments to ensure compatibility with ALVCH family specifications. Check RoHS compliance status against current regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a multiplexed bus exchanger is required rather than a registered variant. Ensure the application demands the specific propagation delay characteristics of the ALVCH series. Verify that the SSOP-56 package fits the available board space constraints compared to TSSOP alternatives.

Part Context

This part belongs to the Texas Instruments 74ALVCH1627x family of universal bus functions. It shares the ALVCH logic architecture but differs from registered bus exchangers like the SN74ALVCH16270 by utilizing multiplexing instead of registration for data path control. It serves as a bridge between different bus widths in digital logic designs.

Replacement Considerations

The SN74ALVCH16271DGGR is a verified substitute offering identical functionality in a TSSOP-56 tape and reel package.
