*Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are
stress ratings only. Functional operation of the device at these or any other conditions beyond those indicated under
“Operating Conditions” is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

Typical figures are at 25°C and are for design aid only; not guaranteed and not subject to production testing.
Note: External Buffer-Capacitance is needed: e.g. 4.7uF between the Supply-Pins.
* Note: At pin PROG a higher voltage (up to 8.5V) as defined for the zero position programming routine.
