    Since none of the above part number are recognizable, I have posted the doubt in SN7400 forum.

    1. There is no similar device in the TO-5 package. The nearest replacement would be the REF5010.

    2. There is no similar device with four-channel AND/NAND inputs. The nearest replacement would be the SN75159 with two inputs each, and a different pinout. The DS8830N is still available from Rochester Electronics.

    3. SN65LBC175, SN75175, MC3486
