† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTE 1: The input voltage ratings may be exceeded if the input current ratings are observed.

‡ 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. OE at ground (0) and all other inputs at 4.5 V.

B. LE at 4.5 V and all other inputs grounded.

C. OE at 4.5 V and all other inputs grounded.
