NOTES:
1) All voltages are referenced to ground.
2) All Pushbutton inputs are internally pulled to the associated Supply IN input or the greatest Supply IN
input for the MPBRST with an internal Impedance of 100k W.
3) A ll outputs are Open Drain and output I OH would be determined by the external pull-up resistor.
4) Measured with outputs open and IN 3.3V or IN 2.5V £ 5.5V.
5) Measured with outputs open and IN 3.3V or IN 2.5V £ 3.6V.
6) Measured using t R = 5μs.
7) Noise immunity - pulses <2μs at a trip level will not cause a RST or NMI .
