Note, the included schematics of a DTL (diode-transistor-logic) gate is wrong on many levels and isn't even something we have used in the last four decades. The CMOS implementation _is_ what we actually use and for drive strength 1 it's literally just this (which isn't hard to understand): https://commons.wikimedia.org/wiki/File:CMOS_NAND.svg https://commons.wikimedia.org/wiki/File:CMOS_NAND.svg
- hmry 4y agoIt's not supposed to be DTL though, it's RTL...
- FullyFunctional 4y agoThanks, my slip up. The rest stands, RTL hasn't been used since before most people here were born.
- CamperBob2 4y agoRTL means something different in FPGA/ASIC-land (Register-Transfer Level.) It simply refers to the practice of low-level 'coding' in an HDL, as opposed to even lower-level schematic or gate-level entry, or higher-level synthesis based on IP core generators or traditional programming languages. See also https://electronics.stackexchange.com/questions/69022/rtl-vs-hdl-whats-the-difference https://electronics.stackexchange.com/questions/69022/rtl-vs... .
- FullyFunctional 4y agoWith only 17,576 different possibilities, TLAs are bound to alias. RTL in electronics can mean both register transfer level and Resistor-Transistor-Logic. If you are old enough, you will have used both.
- CamperBob2 4y agoExactly. I not only missed out on the original RTL, but I never even had to use a 74xx TTL part number that didn't have at least an 'LS' or an 'F' in the middle.
