(1) VCCB = 2.7 V to 3.6 V
(2) All typical values are measured at VCC = 5 V, TA = 25°C.
(3) For I/O ports, the parameter IOZ includes the input leakage current.
(4) This is the increase in supply current for each input that is at one of the specified TTL voltage levels, rather than 0 V or the associated
VCC
