4536
24-bit programmable frequency divider/digital timer with oscillator,
set and reset inputs.  Digitally programmable from 2^1 to 2^24.
Connect MONO via a >10kO resistor to ground for square wave output,
or to a RC network (R to VCC) for a controlled output pulse width.
Maximum guaranteed clock frequency is 500kHz at VCC=+5V (what a pity!!!).
