https://www.ti.com/product/SN7400 https://www.ti.com/product/SN7400 is also "4-ch, 2-input, 4.75-V to 5.25-V bipolar NAND gates". I mentioned BJT and FET, for the latter there is https://www.ti.com/product/SN74AHCT00 https://www.ti.com/product/SN74AHCT00
Might be useful to know what BJT and FET means and then you will see that standard / original TTL is always "bipolar", for example.
- MichaelZuo 3y agoDo you not realize that the design that TI currently sells is different from the 1965 design that we were discussing? They are even manufactured using very different technology. Like I said, just because it shares the same part number and is labelled "bipolar NAND gate" does not mean that it's approximately the same.
- pixelfarmer 3y agoWell, this obviously has nothing to do with boot-up of a CPU anymore, either, so I'm out now.
