Electrical Specifications
These specifications apply for T_A = -10°C to +100°C, unless otherwise noted. Typical values are at T_A = +25°C,
V_IN = 12V; Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless otherwise specified.
Temperature limits established by characterization and are not production tested. (Continued)
