3. CHARACTERISTICS AND SPECIFICATIONS
3.1 Electrical Characteristics
Typical characteristics conditions:
⢠TA = 25ºC, VDD = 12V, GND = 0V
⢠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 = 0V
