HT9032
Absolute Maximum Ratings
Voltages are referenced to VSS, except where noted.
Supply Voltage .........................................-0.5V to 6.0V
Operating Temperature Range ...................0°C to 70°C
All Input Voltages.................................................25mW
Storage Temperature Range ................-40°C to 150°C
Note: These are stress ratings only. Stresses exceeding the range specified under ²Absolute Maximum Ratings² may
cause substantial damage to the device. Functional operation of this device at other conditions beyond those
listed in the specification is not implied and prolonged exposure to extreme conditions may affect device reliabil-
ity.
