Working Principle

The SN74AHC02RGYR is a quad 2-input NOR gates. It consists of four identical NOR gates, each with two inputs and one output. The logic gates are based on the TTL logic family and are based on the CMOS technology. The internal connections of the device are given in the following figure. Each NOR gate consists of two input transistors and one output transistor. The two input transistors are connected in series between the VDD (supply voltage) and the output transistor. The output transistor is connected in series with the ground.When one of the input is logic HIGH (Vdd) and the other input is logic LOW (ground), then the output will be logic LOW (ground). When both inputs are logic HIGH then the output will be logic HIGH (Vdd). When both the inputs are logic LOW then the output will remain logic LOW.The SN74AHC02RGYR device is suitable for operation over a wide temperature range from -55°C to 125°C. It has TTL-compatible inputs and CMOS-compatible outputs. The device is powered from a single supply of 3.3V to 15V.
