Stresses above those listed under Absolute Maximum Ratings may cause perma- nent damage to the device. This is a stress rating only; functional operation of the
HBEN 12 17 DB4
device at these or any other conditions above those listed in the operational
DB0 13 16 DB3
sections of this specification is not implied. Exposure to absolute maximum rating
DB1 14 15 DB2
conditions for extended periods may affect device reliability. 2Transient currents of up to 100 mA will not cause SCR latchup.
