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.
