Hey guys, this is my first post and hopefully my problem has a very easy solution.
I'm trying to generate a complementary negative output clock to drive a BBD chip at high speed (up to 3MHz clock, 1.5MHz when divided). I plan to set up an LMC555 timer as a relaxation oscillator, then send that clock to a CD4013 to be split and divided down, then sent to a CD4049 to be buffered. That's fine and dandy when the clock output is +9V-0V, but I need 0V - -9V. So would this work:
Convert the output of the 555 to a negative clock using reverse series/shunt diodes on the output, then run the CD4013 and 4049 from a Vdd = Gnd and Vss = -9V??? What do you guys think? I really appreciate your help and time!
