=25°C.

[2] This is the bus-hold maximum dynamic current. It is the minimum overdrive current required to switch the input from one state to

another.

[3] For I/O ports, this parameter I

OZ

includes the input leakage current.

[4] This is the increase in supply current for each input that is at the speciﬁed TTL voltage level rather than V
