Stresses beyond those listed under 鈥淎bsolute Maximum Ratings鈥� 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 the absolute maximum rating conditions for extended periods may affect device reliability.
RECOMMENDED DC OPERATING CONDITIONS
(VCC = VCC(MIN) to VCC(MAX), TA = -40掳C to +85掳C, unless otherwise noted. Typical values are at TA = +25掳C, unless
