Description
CD4070 – Quad 2-Input Exclusive-OR (XOR) Gate IC
The CD4070 contains four independent Exclusive OR gates inside a single package. It is oftentimes referred to as a quad package 2-Input XOR gate IC. All four gates share the same power rail and each gate has two input lines and one output line. This IC gives the system designer a way to directly implement the Exclusive-OR Boolean function. The CD4070 makes use of complementary MOS (CMOS) transistors to achieve a broad power supply operating range, low power consumption, and a high noise margin. The IC operates at 5V, 10V, 15V, and even 20V. When operating at 5V the maximum low-level input voltage is 0.5 and the minimum high-level input voltage is 4.5.
