There is probably no ready-to use chip to control a servo with a digital
value. But you have two solutions :
1. Try to program a pulse width modulated signal output. You need a fast
"brain"...
2. With an digital to analog converter and a 555 chip, you could
probably convert an 8 bit signal to the right pwm... Didn't test it
though.
For the first solution, I've already made a simple servo tester, which
use a standard printer port, and a windows proggy (sources included).
You can control up to eight servo's with one parallel port...

Good luck !
