NOTES:
1) All voltages are referenced to ground.
2) PBRST is internally pulled up to V CC with an internal impedance of 50k W typical.
3) Measured with V CC 3 2.7V.
4) Measured with outputs open, V CC ￡ 5.5V, and all inputs at V CC or Ground, except the ST input at
<10kHz duty cycle-square wave or ST input open.
5) Measured with outputs open, V CC ￡ 3.6V, and all inputs at V CC 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 m A when active.
7) Noise immunity: pulses <100ns at pushbutton input will not cause a reset.
8) Must not exceed t TD minimum.
9) Noise immunity: pulses <2 m s at V CCTP minimum will not cause a reset and V CCTP - V CC = 100mV.
