Answer:
Step-by-step explanation:
The corresponding binary voltage levels in digital circuits have two states: a high-voltage state denoted VH corresponding to logical 1 and a low voltage state denoted VL corresponding to logical 0. In electronic digital systems, a transistor is used as a switch.

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” logic state.
