SCOPE: 100mA CMOS SWITCHED-CAPACITOR VOLTAGE CONVERTER 1.5V TO 8V Device Type Generic Number 01 MAX665M(x)/883B Case Outline(s). The case outlines shall be designated in Mil-Std-1835 and as follows: Outline Letter Mil-Std-1835 Case Outline Package Code JA GDIP1-T8 or CDIP2-T8 8 LEAD CERDIP J8 Absolute Maximum Ratings + Supply Voltage (V to GND, or GND to OUT) ...................................................... +8.5V + LV Input Voltage .......................................................................

Ambient Operating Range (T ) ................................................................ -55C to +125C A + Inverter mode V to GND .................................................................. +1.5V dc to +8.0V dc Doubler mode GND to V .............................................................. +2.5V dc to +8.0V dc OUT NOTE 1: OUT may be shorted to GND for 1 sec without damage only if the input supply is limited to less + than 200mA, but shorting OUT to V may damage the device and should be avoided. Also, for + temperatures above +85C, OUT must not be shorted to GND or V , even instantaneously, or device damage may result. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. ---------------------------- Electrical Characteristics of MAX665/883B 19-0470 Rev.
