MC14536B
Programmable Timer
The MC14536B programmable timer is a 24stage binary ripple
counter with 16 stages selectable by a binary code. Provisions for an
onchip RC oscillator or an external clock are provided. An onchip
monostable circuit incorporating a pulsetype 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.

This device contains protection circuitry to guard against damage due to high
static voltages or electric fields. However, precautions must be taken to avoid
applications of any voltage higher than maximum rated voltages to this
highimpedance circuit. For proper operation, Vin and Vout should be constrained
to the range VSS v (Vin or Vout) v VDD.
Unused inputs must always be tied to an appropriate logic voltage level
(e.g., either VSS or VDD). Unused outputs must be left open.
