What is Transistor Transistor Logic (TTL) & Its Working
WebMar 31, 2024 · However, real TTL gate circuits cannot output such perfect voltage levels, and are designed to accept “high” and “low” signals deviating substantially from these ideal values. “Acceptable” input signal voltages range from 0 volts to 0.8 volts for a “low” logic state, and 2 volts to 5 volts for a “high” logic state. WebTTL output voltages and HC input voltages are incompatible, especially between the TTL high-level output voltage (VOH) and the HC high-level input voltage (VIH). This problem … WebHigh-threshold logic (HTL), also known as low-speed logic (LSL) or high-level logic (HLL), is a variant of diode–transistor logic used in environments where noise is very high.
