Ok, this is the current design of our high side pulse transmitter we
are using. Please view with fixed width font.

The circuit should have the following features:
1. True logic; high input produces high output, etc.
2. Operates with Vcc from 24V to 50V.
3. High output is slightly less than Vcc, low is better than 6V less
than Vcc (exa, Vh = Vcc - 0.5, Vl = Vcc - 6.0)
4. Riseing and falling edges should be as fast as possible.
5. Load is from 10mA to a maximum of 125mA, and capacitance from 0 to
about 1.5uF.
The problem with this circuit is the output bounces on the falling
edge. Can anybody suggest a fix, or an alternate circuit?
