Electrical Characteristics

All Min/Max specification limits are guaranteed by design, production testing, and/or statistical

characterization and are valid over the full operating temperature range and power supply range

unless otherwise noted.

Typical values are based on characterization results at default measurement conditions and are

informative only. Default measurement conditions (unless otherwise specified): VIN = 5.0 V,

TA = 25 °C.
