Part Number: CD54HC4024
Other Parts Discussed in Thread: SN54HC4024, CD4024B-MIL

Tool/software:

We currently are using a DESC Standard Microcircuit Drawing part # 8602101CA (High Speed 7-stage Binary Ripple Counter) that was approved to be manufactured by Texas Instruments.

Question # 1: Can you confirm that this part has been obsoleted by Texas Instruments?

Question # 2: If yes, can you recommend what the replacement part number would be from Texas Instrument?

Question # 3: Can you explain what the differences are between Texas Instruments part numbers SN54HC4024 and CD54HC4024?

    1. If it is not shown on the product page, then it was discontinued.

    2. There is no exact replacement. What are your requirements? What military qualifications do you need? The CD4024B-MIL (M38510/05655BCA) would be slower.

    3. The CD device was originally made by RCA; these logic devices were acquired by Harris and later TI.
