Hi,

I am trying to use the TC4432. I am doing the exact circuit of page 7
below. My Vdd is at 12v, and my input is coming from a pic chip running
at 10khz 60% duty cycle. I was pretty sure that I could run the TC4432 with a 5v input and get 12v output with same frequency and duty cycle as the input..

page 7 of microchip

What I am getting at the output is oscillation between 10v low to 12v
high. The frequency is good, but it is not coming down to zero volt
like expected. Any body used this chip and can show me a working
circuit or have any ideas why that is?
