ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

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.

Note 1: Due to the SCR structure inherent in the CMOS process used to fabricate these devices, connecting any terminal to volt-

ages greater than (V+ + 0.3V) or less than (GND - 0.3V) may cause destructive latchup. For this reason, we recommend

that inputs from external sources that are not operating from the same power supply not be applied to the device before its

supply is established, and that in multiple supply systems, the supply to the ICL7665 be turned on first. If this is not possi-

ble, currents into inputs and/or outputs must be limited to ±0.5mA and voltages must not exceed those defined above.
