5 / 25 page 3–143 MC141531 MOTOROLA MAXIMUM RATINGS* (Voltages Referenced to VSS, TA=25˚C) Symbol Parameter Value Unit AVDD,DVDD Supply Voltage -0.3 to +4.0 V VCC VSS-0.3 to VSS+10.5 V Vin Input Voltage VSS-0.3 to VDD+0.3 V I Current Drain Per Pin Excluding VDD and VSS 25 mA TA Operating Temperature -30 to +85 ˚C Tstg Storage Temperature Range -65 to +150 ˚C * Maximum Ratings are those values beyond which damage to the device may occur. Functional operation should be restricted to the limits in the Electrical Characteristics tables or Pin Descrip- tion section. VSS = AVSS = DVSS (DVSS = VSS of Digital circuit, AVSS = VSS of Analogue Circuit) VDD = AVDD = DVDD (DVDD = VDD of Digital circuit, AVDD = VDD of Analogue Circuit) This device contains circuitry to protect the inputs against damage due to high static voltages or elec- tric fields; however, it is advised that normal precau- tions to be taken to avoid application of any voltage higher than maximum rated voltages to this high impedance circuit. For proper operation it is recom- mended that Vin and Vout be constrained to the range VSS < or = (Vin or Vout) < or = VDD. Reliability of operation is enhanced if unused input are con- nected to an appropriate logic voltage level (e.g., either VSS or VDD). Unused outputs must be left open. This device may be light sensitive. Caution should be taken to avoid exposure of this device to any light source during normal operation. This device is not radiation protected.
