ABSOLUTE MAXIMUM RATINGS
VDD to VSS............................................................-0.3V to +5.5V
RS-[5:0] to VSS......................................................-0.3V to +0.3V
All other pins except REG18 and
REG25 relative to VSS.......................... -0.3V to (VDD + 0.3V)*
Operating Temperature Range......................... -40NC to +105NC
Storage Temperature Range............................ -55NC to +125NC
Lead Temperature (soldering, 10s).................................+260NC
Soldering Temperature (reflow).......................................+260NC
*Subject to not exceeding +5.5V.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional opera-
tion of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
