Hi all,
I am working for push-pull output. my rated current is 200mA..
i design the circuit as shown in below....
View attachment untitled.bmp
But it does not work properly....
when my control input low, both pnp and npn transistor On , so the circuit gets damaged...
but for my control input high, the only pnp transistor gets On, and source properly to get my requierd output...
please give ideas to solve my problem.. or any working push pull output stage......

- when my control input is low(0 volt) i want to sink...
- when my control input is high(3.3 volt) i want to source...
