ELM440  
Absolute Maximum Ratings  
Storage Temperature....................... -65°C to +150°C  
Note:  
Stresses beyond those listed here will likely damage  
the device. These values are given as a design  
guideline only. The ability to operate to these levels  
is neither inferred nor recommended.  
Ambient Temperature with  
Power Applied....................................-40°C to +85°C  
Voltage on VDD with respect to VSS............0 to +7.5V  
Voltage on any other pin with  
respect to VSS........................... -0.6V to (VDD + 0.6V)  
Electrical Characteristics  
All values are for operation at 25°C and a 5V supply, unless otherwise noted. For further information, refer to note 1 below.

Notes:  
1. This integrated circuit is produced with a Microchip Technology Inc.’s PIC12C5XX as the core embedded  
microcontroller. For further device specifications, and possibly clarification of those given, please refer to the  
appropriate Microchip documentation.  
2. This spec must be met in order to ensure that a correct power on reset occurs. It is quite easily achieved  
using most common types of supplies, but may be violated if one uses a slowly varying supply voltage, as  
may be obtained through direct connection to solar cells, or some charge pump circuits.  
3. The value of the pullup resistance is supply and temperature dependent.  
4. This specification represents current flowing through the protection diodes when applying large voltages to  
the sync input (pin 5) through a current limiting resistance. Currents quoted are the maximum continuous.
