Absolute Maximum Ratings

Operating Conditions

Static Digital Input Conditions (for specified operating conditions)

For Digital Input pins: TxD, RTS, DTR, PORB, RII, DP, DR(3:1), DM(3:1), HD(2:1).

Note 1:

Output source and sink currents should be kept to a minimum in order to achieve low power

consumption.

Dynamic Characteristics (for specified operating conditions)

Important Note: The "Absolute Maximum Ratings" are stress ratings only, and functional operation of the device at conditions other

than those indicated in the "Operating Conditions" sections of this specification are not implied. Exposure to the absolute maximum

ratings for an extended period may reduce the reliability or useful lifetime of the product.
