• Low voltage (2.5V or 3.3V) VCC applications
• Systems requiring interface between low voltage logic and 5V signal environments

Procurement Notes

Verify the specific suffix 'MTC' corresponds to the 20-pin TSSOP package configuration. Confirm that the component meets RoHS compliance standards if required by your manufacturing process. Check for any lead-free certification documentation provided by the manufacturer. Ensure the operating temperature range of -40°C to +85°C aligns with your environmental requirements. Validate the ESD performance specifications against your system's protection needs.

Selection Notes

Select this component when a 10-bit D-type flip-flop with three-state outputs is required for bus-oriented designs. It is suitable for applications needing 5V tolerance on both inputs and outputs while operating at lower voltages like 2.5V or 3.3V. Consider its high-speed performance and low power consumption for efficient system design. The patented noise reduction features make it appropriate for sensitive electronic environments.
