Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the

Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect

device reliability.

1. The minimum DC input voltage is −0.5 V. During transitions, inputs may undershoot to –2.0 V for periods of less than 20 ns. Maximum DC

voltage on output pins is VCC + 0.5 V, which may overshoot to VCC + 2.0 V for periods of less than 20 ns.

2. Latch-up protection is provided for stresses up to 100 mA on address and data pins from –1 V to VCC + 1 V.

3. This parameter is tested initially and after a design or process change that affects the parameter.

4. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage as determined by wiper position when used as a

potentiometer.

5. Relative linearity is utilized to determine the actual change in voltage between two successive tap positions when used as a potentiometer.

It is a measure of the error in step size.

6. LSB = RTOT / 63 or (RH − RL) / 63, single pot
