Procurement Notes

Verify the specific ordering suffix against official Toshiba Semiconductor and Storage documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with system voltage requirements and thermal management needs. Confirm availability status as distribution channels may list obsolete or discontinued variants. Cross-reference pinout diagrams with target PCB layout designs prior to procurement.

Selection Notes

Select this component when an octal D-type flip-flop with three-state outputs is required for high-speed data latching. The 2V to 5.5V supply range supports various logic families. Consider the 20-TSSOP package dimensions for board space constraints. Evaluate propagation delay and clock frequency limits against system timing requirements. Verify that the 8mA output drive current meets load capacitance specifications.
