Flip Flops Procurement Notes

Verify the specific manufacturer part number MM74C374N against official onsemi documentation to confirm authenticity and technical specifications. Ensure the procurement source provides valid datasheets matching the 74C series characteristics. Confirm that the received components match the 20-PDIP package dimensions and pinout configuration. Check for any obsolescence notices or lifecycle status updates from the manufacturer prior to finalizing orders.

Flip Flops Selection Notes

Select this component when designing circuits requiring octal storage with three-state outputs and wide voltage tolerance. It is suitable for through-hole PCB layouts where DIP packaging is preferred over surface-mount alternatives. Consider the 10 MHz clock speed limit and 160ns propagation delay when determining suitability for high-speed timing requirements. Evaluate the static current consumption and output drive capabilities against the specific load conditions of the target application.

Flip Flops Part Context
