ELECTRICAL SPECIFICATIONS
Specifications are for an Operating Junction Temperature of T J = 25°C; limits applying over the full Operating Junction
Temperature range are denoted by a “?”. Minimum and Maximum limits are guaranteed through test, design, or statistical
correlation. Typical values represent the most likely parametric norm at T J = 25°C, and are provided for reference purposes
only. Unless otherwise indicated, V CC = V IN = 3.3V.
