*Stresses above those listed under “Absolute Maximum Ratings” may cause

permanent damage to the device. This is a stress rating only and functional

operation of the device at these or any other conditions above those listed in the

operational sections of this specification is not implied. Exposure to absolute

maximum ratings for extended periods of time may affect device reliability.

PIN FUNCTION DESCRIPTION

Mnemonic Pin No.

Function
