NOTES
1 Full Scale Range (FSR) is 3V.
2 Guaranteed but not production tested.
3 Digital input levels should not go below ground or exceed the positive supply voltage, otherwise damage may occur.
4 See Figures 1 and 2.
5 For reference input pulse: tR = tF > 100 ns.

NOTES:
1 Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. This is a
stress rating only and functional operation at or above this specification is not implied. Exposure to maximum rating
conditions for extended periods may affect device reliability.
2 Any input pin which can see a value outside the absolute maximum ratings should be protected by Schottky diode clamps
(HP5082-2835) from input pin to the supplies. All inputs have protection diodes which will protect the device from short
transients outside the supplies of less than 100mA for less than 100µs.
