This document introduces a series of logic gate products, including Quad 2-Input NAND Gate, Quad 2-Input NOR Gate, Hex Inverter, Triple 3-Input NAND Gate, and Dual 4-Input NAND Gate. These products use complementary MOS (CMOS) technology and have wide power supply operating range, low power consumption, high noise immunity, and symmetric controlled rise and fall times. The 54C-74C logic family is functionally and pin compatible with the 54-74 series devices, minimizing design time for designers familiar with the standard 54-74 logic family. All inputs are protected from damage due to static discharge by diode clamps.
