CD4085-Dual 2-wide, 2-input AND-OR-Invert Gate
Package DIP Series CD4000 (CMOS)
CD4085 overview
CD4085 belongs to the 4000 Series CMOS Logic Family of Integrated Circuits (IC's) constructed with N- and P-channel enhancement mode transistors. CD4085 has Dual 2-wide, 2-input AND-OR-Invert Gate
CD4085 has a supply voltage range of 5V to 20V, which is much higher than any contemporary logic family. It has buffered output which improves transfer characteristics by providing very high gain. All inputs are protected against static discharge with diodes to VDD and VSS.
