Flip Flops Procurement Notes

Verify the specific suffix 'E4' indicates lead-free compliance and RoHS status as per manufacturer documentation. Confirm the SOIC-14 package dimensions and pinout match design requirements. Ensure the 4.5V to 5.5V supply voltage range aligns with system power rails. Check for any recent lifecycle notifications or obsolescence warnings from Texas Instruments before finalizing procurement plans.

Flip Flops Selection Notes

Select this component when TTL-level interface compatibility is required alongside ACT-series speed and drive strength. The SOIC-14 package suits surface-mount assembly processes. Consider the ±24 mA output current for driving moderate loads without additional buffering. Verify that the 11 ns propagation delay meets the timing constraints of the target digital application.

Flip Flops Part Context

This part is a member of the Texas Instruments SN74ACT family, which bridges the performance gap between standard Schottky TTL and advanced CMOS technologies. The SN74ACT74 variant specifically provides two independent D-type flip-flops in a single package, offering a compact solution for sequential logic applications requiring high-speed operation and robust noise immunity.

Flip Flops Replacement Considerations

SN74ACT74DR is a compatible alternative within the same series and package type.
