WebDec 21, 2024 · No, it is not only about speed but drive capacity. In general you can get more current out of TTL, there are TTL devices that do not have the equivalent CMOS parts so functionality is an issue as well. The fastest TTL will still go faster than the fastest CMOS. It is just that the slowest CMOS is not as slow as it used to be. WebVoltage Tolerance of CMOS Gate Inputs . CMOS gate circuits have input and output signal specifications that are quite different from TTL. For a CMOS gate operating at a power supply voltage of 5 volts, the acceptable input signal voltages range from 0 volts to 1.5 volts for a “low” logic state, and 3.5 volts to 5 volts for a “high ... how do you test a ballast with a multimeter
