† _{All typical values are at VCC = 5 V, TA = 25°C.}
‡ _{For I/O ports, the parameters IIH and IIL include the off-shoot 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.}
¶ _{ICCH and ICCL are measured in the A-to-B mode.}
