74S37N Quad 2-Input Positive NAND Buffer IC

74S37N designed as a high-speed Quad 2-Input Positive NAND Buffer IC fabricated in low power schotkey technology. These devices come with four independent 2-input Positive-NAND buffers/drivers. They perform the Boolean functions Y = A • B or Y = A + B in positive logic. The SN55188 is designed for operation over the full military temperature range of −55°C to 125°C. 74S37N 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 is also sometimes referred to as a universal logic gate, as it can be 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.

A buffer designed basically as a logic gate that passes its input, unchanged, to its output. The main function of a buffer is to regenerate the input, usually using a strong high and a strong low. A buffer has one input and one output, in which its output is always equal to its input. Buffers IC also used to increase the propagation delay of circuits by driving the large capacitive loads. Whereas the Line drivers designed as a special type of buffer that has the ability to drive a transmission line or cable that may be quite long. They also have the ability to adapt the input logic format to the specific line driving standard.  These IC generally used to isolate other gates or circuit stages from each other. Thereby preventing the impedance of one circuit from affecting the impedance of another circuit.
