Procurement Notes
Verify the manufacturer designation as National Semiconductor or Texas Instruments, as TI acquired NS. Confirm the package type matches your PCB footprint requirements. Ensure the part number suffix corresponds to the specific temperature grade and packaging format needed for your production environment.
Selection Notes
Select this component when a compact solution for multiple AND-OR logic combinations is required. Consider the CMOS technology benefits for low-power designs. Verify that the input voltage levels are compatible with the driving logic family used in the circuit design to ensure proper signal integrity.
Part Context
This part belongs to the CD4000 series of CMOS logic ICs, originally developed by National Semiconductor and now maintained by Texas Instruments. The series is known for its versatility in digital logic applications, offering a wide range of gates, flip-flops, and counters in standard packages.
Replacement Considerations
Compatible substitutes include the CD4019BC from Texas Instruments, which shares identical logical functionality and pinout. Verify that any replacement maintains the same voltage specifications and package dimensions to ensure direct interchangeability without circuit modification.
