Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required packaging formats such as tape and reel or cut tape. Confirm that the component meets RoHS standards if environmental compliance is mandatory for the assembly process. Cross-reference the manufacturer part number against official Toshiba documentation to validate authenticity and avoid counterfeit components during sourcing.

Selection Notes

Select this component when a single-bit memory element with preset and reset controls is required in compact surface-mount designs. Ensure the operating voltage aligns with the 2V to 6V specification and verify that the 67 MHz clock limit satisfies system timing requirements. Consider the 8-VFSOP package dimensions for PCB layout constraints and thermal management needs.
