What is 74HC05?


This is Hex inverter.

The basic TTL inverter circuit consists of a transistor and a resistor connected in series between the positive supply voltage and ground. The input signal is connected to the base of the transistor, and the output signal is taken from the collector of the transistor. When the input signal is low, the transistor is turned off and the output signal is high. When the input signal is high, the transistor is turned on and the output signal is low. The resistor is used to limit the current flowing through the transistor and protect it from damage.

TTL inverters are commonly used in digital circuits to perform logical operations such as NOT, AND, OR, and XOR. They are also used as building blocks for more complex digital circuits such as counters, shift registers, and memory devices.
