(1)

All voltages are with respect to the potential at the GND pin.

(2)

All limits are ensured by design, test and/or statistical analysis. All electrical characteristics having room-temperature limits are tested

during production with TJ = 25C. All hot and cold limits are ensured by correlating the electrical characteristics to process and

temperature variations and applying statistical process control.

Capacitors: Low-ESR Surface-Mount Ceramic Capacitors are (MLCCs) used in setting electrical characteristics
