CM1293

www.DataSheet4U.com CM1293 2, 4, and 8-Channel Low Capacitance ESD Protection Arrays Features 2, 4, and 8 channels of ESD protection Provides ESD protection to IEC61000-4-2 - 8kV contact discharge - 15kV air discharge Low loading capacitance of 2.0pF max. Low clamping voltage Channel I/O to I/O capacitance 1.5pF typical Zener diode protects supply rail and eliminates the need for external by-pass capacitors Each I/O pin can withstand over 1000 ESD strikes Available in SOT, and MSOP packages Lead-free version available Product Description The CM1293 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 positive or negative ESD current pulse to either the positive (VP) or negative (VN) supply rail. A Zener diode is embedded between VP and VN, offering two advantages. First, it protects the VCC rail against ESD strikes, and second, it eliminates the need for a bypass capacitor that would otherwise be needed for absorbing positive ESD strikes to ground. The CM1293 will protect against ESD pulses up to (±15kV air, ±8kV contact discharge) per the IEC 61000-4-2 Level 4 standard. This device is particularly well-suited for protecting systems using high-speed ports such as USB2...
