CD4077 belongs to the CD4000 IC series. CD4077 is a Quad 2-input exclusive NOR gate gate, designed by using the complementary MOS (CMOS) technology, integrated with P & N type enhancement mode transistors. This IC allows design engineers to directly implement positive logic exclusive NOR gate. CD4077 has a wide range working voltages and conditions. The offers many features such as high noise immunity and static protection through clamping diodes.

Features:

• Four Independent 2-input EXCLUSIVE-NOR Gates
• High Noise Immunity
• Wide Operating Voltage Range
• Operating Temperature to 85°C
• Low Power CMOS
