† 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
