† Notice: Stresses above those listed under “Absolute
Maximum Ratings” may cause permanent damage to the
device. This is a stress rating 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.
†† See Section 4.1.2 “Input Voltage and Current Limits”.

Note 1: The SC70 package is only tested at +25°C.
2: All parts with date codes February 2007 and later have been screened to ensure operation at VDD = 6.0V. However, the
other minimum and maximum specifications are measured at 1.8V and 5.5V
