Hello,biasswitching.png

I have a biasing circuit as shown picture above. My intention is to switch 5VDC between to legs A, and B.

 

i-When I apply HIGH to IN (pin-1), I am measuring 5V at branch A (pin-6), and 0V at branch B (pin-4) as expected.


ii-However, when I apply LOW to the IN (pin-1), I am measuring 4.8V at branch A (pin-6) and it is decreasing to 3.8V during the measurement; it is supposed to be 0V under this condition for branch A. The Branch B, in this state, measures 5V as intended.

 

Please help me to figure out what I may be doing wrong;

 

Thanks
