3. CHARACTERISTICS AND SPECIFICATIONS

3.1 Electrical Characteristics

Typical

characteristics conditions:

•TA =25 °C, VDD =12V, GND= 0 V

• All voltages are measured with respect to GND.

• Unless otherwise specified, all currents are positive

when flowing into the IC.

Minimum/Maximum

characteristics conditions:

•TJ = -40°C to +125 °C, VDD = 11V to 17V, GND = 0 V
