Electrical Characteristics (Continued)
V
CC = 3.3V unless otherwise indicated. Limits in standard type are for TJ = 25˚C only; limits in boldface type apply over the
junction temperature (T
J) range of -40˚C to +125˚C. Minimum and Maximum limits are guaranteed through test, design, or sta-
tistical correlation. Typical values represent the most likely parametric norm at T
J = 25˚C, and are provided for reference pur-
poses only.

Note 1: Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating ratings indicate conditions for which the device
operates correctly. Opearting Ratings do not imply guaranteed performance limits.
Note 2: The human body model is a 100pF capacitor discharged through a 1.5k resistor into each pin.
