CHARACTERISTICS

Absolute Maximum Ratings†

Supply Voltage ................................................................+22V

Input Voltage, IN A or IN B .......... (VDD + 0.3V) to (GND – 5V)

† Notice: Stresses above 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 above those

indicated in the operation sections of the specifications is not

implied. Exposure to Absolute Maximum Rating conditions for

extended periods may affect device reliability.

DC CHARACTERISTICS

Electrical Specifications: Unless otherwise noted, over operating temperature range with 4.5V ≤ VDD ≤ 18V.
