74LS27 IC is a member of the 74XXYY IC series. There are three NOR gates in the chip and each gate has three inputs, hence the name Triple 3- Input NOR Gate. The 74LS27 IC has a wide range of working voltage, a wide range of working conditions, and directly interfaces with CMOS, NMOS, and TTL. The output of the IC always comes in TTL which makes it easy to work with other TTL devices and microcontrollers. The IC 74LS27 is smaller in size and it has a much 'FASTER SPEED' which makes it reliable in every kind of device.
