the cd4012 is a dual 4-input nand gate. the outputs are fully buffered for the highest noise immunity and pattern insensitivity to output impedance.
it operates over a recommended vdd power supply range of 3v to 15v referenced to gnd (usually ground). unused inputs must be connected to vdd, gnd, or another input.
wide supply voltage range from 3v to 15v
fully static operation
5v, 10v, and 15v parametric ratings
standardized symmetrical output characteristics
inputs and outputs are protected against electrostatic effects
specified from -40℃ to 105℃
