Procurement Notes

Verify the specific suffix 'DL' corresponds to the 56-TSSOP package and tape-and-reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation, as some variants may differ. Ensure the ordering quantity aligns with standard factory pack sizes. Cross-reference the datasheet revision date to guarantee compatibility with current design specifications.

Selection Notes

Select this component when a 12-bit universal bus function is required in a compact surface-mount package. The ALVCHR series offers improved performance over standard LVCH devices. Verify that the 3.6 V maximum supply voltage meets system requirements. Consider the 56-pin footprint constraints during PCB layout planning.

Part Context

This part belongs to the Texas Instruments SN74ALVCHR family, which combines advanced CMOS technology with high-speed performance. The ALVCHR series is designed for low-voltage applications requiring robust drive capabilities.
