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˚C
Soldering temperature of leads (10 seconds) ............. +300˚C
ESD protection on all pins ..................................................≥ 4 kV
*Notice: Stresses above those listed under “Maximum ratings”
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 specification is not implied. Exposure to maximum rating
conditions for extended periods may affect device reliability.
