3. Latch-up protection is provided for stresses up to 100 mA on address and data pins from −1 V to V_CC + 1 V.
4. This parameter is tested initially and after a design or process change that affects the parameter.
5. I_W = source or sink.
6. Relative variation is a measure of the error in step size between taps = log (V_W(N)) − log(V_W(N−1)) = 0.045  0.003.
