ABSOLUTE MAXIMUM RATINGS

COMMENT

Junction Temperature under bias...... -65C to +135C

Storage temperature ......................... -65°C to +150°C

Voltage on CS, INC, U/D and VCC

with respect to VSS ................................. -1V to +7V

RH, RW, RL to ground..........................................+10V

Lead temperature (soldering 10s) ..................... 300°C

IW (10s) ..............................................................±6mA

Stresses above those listed under “Absolute Maximum

Ratings” may cause permanent damage to the device.

This is a stress rating only; 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 rating condi-

tions for extended periods may affect device reliability.
