MC14536屬于集成電路（IC）的可編程定時(shí)器振蕩器。由安森美半導(dǎo)體公司制造生產(chǎn)的MC14536可編程定時(shí)器和振蕩器可以設(shè)置用來(lái)以指定頻率提供定時(shí)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.
