Detailed explanation-1: -The standard, 4000 series, CMOS IC is the 4011, which includes four independent, two-input, NAND gates.
Detailed explanation-2: -Explanation: 7400 IC’s pin has total 14 pin. Pin no 7 use for GND and pin no 14 used for +vcc and remaining pins used for connections. For a NAND gate two inputs are required and one output is obtained means for NAND gate 3 pin connections are required. Thus, a 7400IC contains 4 NAND gates with each having 3 pins.
Detailed explanation-3: -NAND gates help detect if a single input to a digital system has gone low. For example, a simple security system consisting only of NAND gates could be used to monitor the status of sensors connected to windows and/or doors. If a window/door is closed, the sensor sends a logical “1” signal to the security system.
Detailed explanation-4: -The first part number in the series, the 7400, is a 14-pin IC containing four two-input NAND gates. Each gate uses two input pins and one output pin, with the remaining two pins being power (+5 V) and ground.
