7.5 Electrical Characteristics

Limits in standard type are for TJ = 25°C only; limits in boldface type apply over the junction temperature (TJ) range of -40°C to +125°C. Minimum and Maximum limits are specified through test, design, or statistical correlation. Typical values represent the most likely parametric norm at TJ = 25°C, and are provided for reference purposes only. Unless otherwise stated the following conditions apply: ICC = 2 mA, OUT Pin = 48V above VEE, all voltages are with respect to VEE. See (1).
