As of my last update in September 2021, there is no such thing as "Shottky TTL (STTL)" logic gate. It seems like there might be a confusion or a mix-up of terminologies.
However, I can provide you with information about "Schottky TTL" logic gates.
Schottky Transistor-Transistor Logic (STTL) is a type of digital logic family that was commonly used in the past but has largely been replaced by other families like CMOS (Complementary Metal-Oxide-Semiconductor). STTL gates are based on bipolar junction transistors and use Schottky diodes to improve their performance.
The addition of Schottky diodes in STTL gates reduces the switching delay and power consumption, making them faster than standard TTL (Transistor-Transistor Logic) gates. The Schottky diodes, due to their low forward voltage drop, allow for faster switching times, improving the overall speed of the logic gates.
It's essential to note that with the advancement of semiconductor technology, Schottky TTL has been largely replaced by other logic families like CMOS, which offer better power efficiency and integration density.
Again, if there are any new developments or changes beyond my knowledge cutoff date, I won't be aware of them. So, it's always a good idea to double-check the latest information from reliable sources.
