17 DC ELECTRICAL CHARACTERISTICS

ABSOLUTE MAXIMUM RATINGS

Voltage Range on Any Input, Bidirectional or Open Drain

Output Lead with Respect to VSS…..………………………………………………………………………..-0.3V to +5.5V

Supply Voltage (VDD) Range with Respect to VSS…..……………………………………………………...-0.3V to +3.63V

Ambient Operating Temperature Range……………………………………………………………………..-40°C to +85°C

Junction Operating Temperature Range……………………………………………………………………-40°C to +125°C

Storage Temperature Range………………………………………………………………………………...-55°C to +125°C

Soldering Temperature..…………………………………………………………….See IPC/JEDEC J-STD-020 Standard

These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated in the operation

sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time can affect device

reliability. Ambient Operating Temperature Range is assuming the device is mounted on a JEDEC standard test board in a convection cooled

JEDEC test enclosure.

Note: The typical values listed below are not production tested.
