The device features ultra-low R ON of 1 at 4.5 V V CC and operates over the wide V CC range of 1.65 V to 5.50 V. The FS1259 allows for reduced input thresholds on the select pins. The device is fabricated with sub-micron CMOS technology to achieve fast switching speeds and is designed for break-before-make operation.

3 bsolute Maximum Ratings Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The absolute maximum ratings are stress ratings only. Symbol Parameter Min. Max.
