CM1231

Issue X-1 www.DataSheet4U.com CM1231 Two-Channel PicoGuard XPTM ESD Clamp Protection Array Features Two channels of ESD protection Exceeds ESD protection to IEC61000-4-2 Level 4: ±12kV contact discharge (OUT pins) Two-stage matched clamp architecture Matching-of-series resistor (R) of ±10mΩ typical Flow-through routing for high-speed signal integrity Differential channel input capacitance matching of 0.02pF typical. Improved powered ASIC latchup protection Dramatic improvement in ESD protection vs. best in class single-stage diode arrays 40% reduction in peak clamping voltage 40% reduction in peak residual current Withstands over 1000 ESD strikes* Available in a SOT23-6 package Product Description The CM1231 is a member of the XtremeESDTM product family and is specifically designed for next generation deep submicron ASIC protection. These devices are ideal for protecting systems with high data and clock rates and for circuits requiring low capacitive loading such as USB 2.0. The CM1231 incorporates the PicoGuard XPTM dual stage ESD architecture which offers dramatically higher system level ESD protection compared with traditional single clamp designs. In addition, the CM1231 provides a controlled filter roll-off for even greater spurious EMI suppression and signal integrity. The CM1231 protects against ESD pulses up to ±12kV contact on the “OUT” pins per the IEC 61000-4-2 standard. The device also features easily routed "pass-through" differential pin...
