CHARACTERISTICS
1.1 Maximum Ratings*
VCC...................................................................................7.0V
All inputs and outputs w.r.t. VSS ............... -0.6V to VCC +1.0V
Storage temperature .....................................-65°C to +150°C
Ambient temp. with power applied ............. -65°C to +125°CC
Soldering temperature of leads (10 seconds) ............. +300°C
ESD protection on all pins ..................................................⥠4 kV
*Notice: Stresses above those listed under âMaximum ratingsâ
may cause permanent damage to the device. This is a stress rat-
ing only and functional operation of the device at those or any
other conditions above those indicated in the operational listings
of this speciï¬cation is not implied. Exposure to maximum rating
conditions for extended periods may affect device reliability.
