74LS12 Triple 3-Input Positive NAND Gate IC

74LS12 designed as a high-speed three independent 3-input positive-NAND gates IC fabricated in low power schotkey technology. It comes With Collector Outputs contains three 3 input independent gates each of which performs the positive logic NAND function. 74LS12 IC can be soldered directly to the circuit board or easily mounted on a 14 pin IC base.  They perform the Boolean functions Y = A • B • C or Y = A + B + C in positive logic.74LS12 Operates at a supply voltage at a range between 4.5V and to a maximum of 5.5V and the input logic levels to the device in ‘0’ (LOW) state is max. 0.7V and for ‘1’ (HIGH) state is min 2V.  This IC  is designed for operation over the full military temperature range of −55°C to 125°C. 74LS12 manufactured in 14−pin plastic PDIP wide body surface-mount packages.

NAND gate defined as a digital logic gate most commonly used in DLD applications. It also sometimes referred to as a universal logic gate and used to implement any logic gate or expression in existence. Incase, if any one of the inputs to the NAND gate switch to high, the output of the gate will always be a logical low. On the other hand, a NAND gate yields a logical high only when all of its inputs set to LOW.
