Product Description

The CM1235 is ideal for protecting systems with high data and clock rates or for circuits requiring low capacitive loading and tightly controlled signal skews (with channel−to−channel matching at 2 max deviation).

The device is particularly well−suited for protecting systems using high−speed ports such as DisplayPort or HDMI, along with corresponding ports in removable storage, digital camcorders, DVD−RW drives and other applications where extremely low loading capacitance with ESD protection are required.

The CM1235 also features easily routed “pass−through” pinouts in a RoHS compliant (lead−free), 4.0 mm x 1.7 mm, 16−lead WDFN, small footprint package.
