for details. All of the devices in the MAX22700–MAX22702 family are available in an 8-pin, narrow-body SOIC package with 4mm of creepage and clearance. The package material has a minimum comparative tracking index (CTI) of 600V, which gives it a group I rat ing in creepage tables. All devices are rated for operation at ambient temperatures of -40°C to +125°C. 19-100581; Rev 2; 9/19
