All typical values are at VCC = 5 V, TA = 25°C.
For I/O ports (QA thru QH), the parameters IIH and IIL include the off-state output current.
§ 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 OE1, OE2, and CLK at 4.5 V.
