CM1223 - California Micro Devices

CM1223 Industry First Low Capacitance ESD Protection Arrays

The CM1223 family of diode arrays has been designed to provide ESD protection for electronic components or sub-systems requiring minimal capacitive loading. These devices are ideal for protecting systems with high data and clock rates or for circuits requiring low capacitive loading. Each ESD channel consists of a pair of diodes in series which steer the pos.
