CM1231-02SO Datasheet, PDF (1/12 Pages) ON Semiconductor – 2,4,8-Channel Low-Capacitance ESD Protection Array
CM1231-02SO
2, 4 and 8-Channel
Low-Capacitance ESD
Protection Array
Product Description
The CM1231−02SO 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 CM1231−02SO incorporates dual stage ESD architecture
which offers dramatically higher system level ESD protection
compared with traditional single clamp designs. In addition, the
CM1231−02SO provides a controlled filter roll−off for even greater
spurious EMI suppression and signal integrity.
The CM1231−02SO protects against ESD pulses up to ±12 kV
contact on the “OUT” pins per the IEC 61000−4−2 standard.
The device also features easily routed “pass−through” differential
pinouts in a 6−lead SOT23 package.
