MC14536B
Programmable Timer
counter with 16 stages selectable by a binary code. Provisions for an
on−chip RC oscillator or an external clock are provided. An on−chip
monostable circuit incorporating a pulse−type output has been
included. By selecting the appropriate counter stage in conjunction
with the appropriate input clock frequency, a variety of timing can be
achieved.

Stresses exceeding Maximum Ratings may damage the device. Maximum
Ratings are stress ratings only. Functional operation above the Recommended
Operating Conditions is not implied. Extended exposure to stresses above the
Recommended Operating Conditions may affect device reliability.
