NOTES:
1. All voltages are referenced to ground.
2. Measured with both IN3.3V & IN2.5V
≥ 2.7V.
3. Measured with both IN3.3V & IN2.5V
≤ 2.7V.
4. 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 100 k
Ω.
5. All outputs are Open Drain and output IOH would be determined by the external pull-up resistor.
6. Measured with outputs open and IN3.3V or IN2.5V
≤ 5.5V.
7. Measured with outputs open and IN3.3V or IN2.5V
≤ 3.6V.
8. Measured using tR = 5 µs.
9. Noise immunity - pulses <2 µs at a trip level will not cause a RST or NMI .
