MC14536B屬于集成電路（IC）的可編程定時器振蕩器。由安森美半導體公司制造生產的MC14536B可編程定時器和振蕩器可以設置用來以指定頻率提供定時脈沖的器件。

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.
