All typical values are at VCC = 5 V, TA = 25°C.
Not more than one output should be shorted at a time, and the duration of the short circuit should not exceed one second.
NOTE 2: ICC is measured with the outputs open under the following conditions:
A. Inputs A, B, 1C3, and 2C3 at 4.5 V, other inputs grounded
B. All inputs grounded
C. Inputs 1G and 2G at 4.5 V, other inputs grounded
