† 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.

NOTES:

2. ICCH is measured with all outputs open, all data inputs and enable input at 4.5 V, and the clock input at 4.5 V after being momentarily

grounded.

3. ICCL is measured with all outputs open, all data inputs and enable input at 0 V, and the clock input at 4.5 V after being momentarily

grounded.
