The MC14536B programmable timer is a 24–stage binary ripple 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.
