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 0.4V ≤ VIN ≤ VCC.
2. SOCP = VIL, 0.4 ≤ VOUT ≤ VCC.
3. ICC measurements are made with outputs open.
4. RS = FL/DIR = W = VCC - 0.2V; SOCP = 0.2V; all other inputs ≥ VCC - 0.2 or ≤ 0.2V.
5. For SO, IOUT = -4mA.
6. For SO, IOUT = 16mA.
7. Measurements are made after reset.
