shutdown using a pulse generator. The pulse generator can be set to switch between 0V 
and 5V. The enable and disable characteristics can be determined by obserV

IN

g the 

output voltage at V

OUT

 and the input current at V

IN

. The pulse generator frequency will be 

in the 100s of Hertz range. When the part is disabled, V

OUT

 will be discharged to ground 

via an internal pull down transistor. The data sheet contains example waveforms showing 
the on and off characteristics of V

OUT

. In actual applications, the 2N7002 can be replaced 

with an open-drain transistor associated, for example, with a system controller.
