2 / 8 page Sensors 2 Freescale Semiconductor MC145017 Figure 2. Block Diagram This device contains circuitry to protect the inputs against damage due to high static voltages or electric fields; however, it is advised that normal precautions be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance circuit. For proper operation it is recommended that Vin and Vout be constrained to the range VSS ≤ (Vin or Vout) ≤VDD. Table 1. Maximum Ratings(1) (Voltages referenced to VSS) 1. Maximum Ratings are those values beyond which damage to the device may occur. Rating Symbol Value Unit DC Supply Voltage VDD -0.5 to + 15 V Input Voltage, All Inputs Except Pin 8 Vin -0.25 to VDD +0.25 V DC Current Drain per Input Pin, Except Pin 15 = 1 mA I 10 mA DC Current Drain per Output Pin I 30 mA Operating Temperature Range TA -10 to +60 °C Storage Temperature Range Tstg -55 to +125 °C Reverse Battery Time tRB 5.0 s Table 2.
