WebbTransistor-Transistor Logic (TTL) Transistor-transistor logic (TTL or T 2 L) integrated circuits were introduced in the late 1960s. TTL grew rapidly to be the most popular type of digital integrated circuit. Many improvements and variations have been added since its introduction. Today TTL continues to be a popular choice of integrated circuits. WebbVoltage Tolerance of TTL Gate Inputs. TTL gates operate on a nominal power supply voltage of 5 volts, +/- 0.25 volts. Ideally, a TTL “high” signal would be 5.00 volts exactly, and a TTL “low” signal 0.00 volts exactly. However, real TTL gate circuits cannot output such perfect voltage levels, and are designed to accept “high” and ...
