NOTES:
1) All voltages are referenced to ground.
2) PBRST is internally pulled up to VCC with an internal impedance of 50k
W typical.
3) Measured with VCC
2.7V.
4) Measured with outputs open, VCC
5.5V, and all inputs at VCC or Ground, except the ST input at
<10kHz duty cycle-square wave or ST input open.
5) Measured with outputs open, VCC
3.6V, and all inputs at VCC or Ground, except the ST input at
<10kHz duty cycle-square wave or ST input open.
6) The ST input current is defined as the average input current when ST is driven high or low. This input
must be driven high or low by an output that can source or sink at least 200
mA when active.
7) Noise immunity: pulses <100ns at pushbutton input will not cause a reset.
8) Must not exceed tTD minimum.
9) Noise immunity: pulses <2
ms at VCCTP minimum will not cause a reset and VCCTP - VCC = 100mV.
