Procurement Notes

Verify the specific datasheet revision and manufacturer documentation when sourcing the TLC20CN. Confirm that the PDIP-20 package matches the design requirements. Ensure compatibility with the intended resistor programming network for accurate cutoff frequency settings. Check for any obsolescence notices or lifecycle status updates from Texas Instruments before finalizing procurement plans.

Selection Notes

Select the TLC20CN when a dual-channel switched capacitor filter with resistor programmability is required. Consider its CMOS construction for low power consumption needs. Evaluate the PDIP-20 package constraints against board space limitations. Ensure the application benefits from the universal filtering nature of the component rather than fixed-function alternatives.
