Specialty Logic Procurement Notes

Verify the specific ordering suffix F3A corresponds to the ceramic CDIP package configuration required for your design. Confirm that the military grade qualification aligns with project specifications. Ensure proper handling procedures are followed due to the sensitivity of CMOS devices to electrostatic discharge during installation and testing phases.

Specialty Logic Selection Notes

Select this component when a 4-bit binary addition function is required with fast carry capabilities in harsh environments. The ACT series offers speed comparable to bipolar FAST logic but with significantly reduced power consumption. Verify input compatibility with existing logic families and ensure adequate bypass capacitance is implemented near the power terminals.

Specialty Logic FAQ

Can the CD54ACT283F3A operate with active-LOW operands?

Yes, due to the symmetry of the add function, the device can be used with either all active-HIGH or all active-LOW operands.

What is the recommended connection for the carry-in input if no carry-in is present?

When using positive logic, the carry-in input must be tied LOW if there is no carry-in.
