1. Stresses greater than those listed under ABSOLUTE MAXIMUM

RATINGS may cause permanent damage to the device. This is a stress

rating only and functional operation of the device at these or any other

conditions above those indicated in the operational sections of this

specification is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect reliability.

NOTES:

1. Measurements with 0.4 ≤ VIN ≤ VCC.

2. SOCP ≤ VIL, 0.4 ≤ VOUT ≤ VCC.

3. ICC measurements are made with outputs open.

4. RS = FL/RT = W = VCC -0.2V; SOCP ≤ 0.2V; all other inputs ≥ VCC -0.2V or ≤ 0.2V.
