Flip Flops Procurement Notes

This specific part number is officially listed as obsolete and no longer manufactured by onsemi. Procurement requires verification of availability through authorized distributors or third-party suppliers. Cross-reference with equivalent active components from other manufacturers is necessary for new designs. Verify pin compatibility and electrical specifications before integrating substitute parts into existing systems.

Flip Flops Selection Notes

Engineers should evaluate alternative active hex D-type flip-flops from the 74AC series when designing new hardware. Key selection criteria include matching the 16-SOIC package dimensions, verifying the 2V to 6V operating voltage range, and confirming the presence of a master reset input. Ensure that the replacement device maintains the required propagation delay characteristics and output current capabilities for the target application timing constraints.

Flip Flops Part Context

The 74AC174SC belongs to the broader 74AC logic family, which offers higher speed performance compared to standard 74HC devices while maintaining CMOS low-power advantages. This specific variant implements six independent D-type flip-flops within a single package, providing a compact solution for multi-bit data handling applications requiring synchronous operation and global reset control.
