8.2. Specifications
8.2.1. Absolute Maximum Ratings
Input voltage:
any ADC port input: .................................................. -0.5 to +5.5 V
7
any ADC GATE input: ................................................ -0.5 to + 7 V
8
any Counter input: ..........................................................-0.5 to +6 V
7 Max. DC undershoot below GND must be limited to –0.5 V or 10 mA. During transitions internal device pins may undershoot to –
2.0 V and overshoot to +7.0 V, provided it lasts less than 10 ns and the forcing current is limited to 200 mA.
8 Max. undershoot below GND may be exceeded as long as the max. current is limited to 50mA
