Note 1

‘‘Absolute Maximum Ratings’’ are those values beyond which the safety of the device cannot be guaranteed They are not meant to imply that the devices

should be operated at these limits The tables of ‘‘Electrical Characteristics’’ provide conditions for actual device operation

Note 2

Unless otherwise specified minmax limits apply across the supply and temperature range listed in the table of Recommended Operating Conditions All

typical values given are for VCC e 5V and TA e 25 C

Note 3

All currents into device pins are positive all currents out of device pins are negative All voltages are referenced to ground unless otherwise specified

Note 4

Only one output at a time should be shorted
