Electrical Characteristics (continued)
Limits apply over the recommended operating junction temperature range of -40°C to +125°C, unless otherwise stated.
Minimum and maximum limits are ensured 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: VIN = 24 V.
