集电极开路 Open collector(重定向自Open Drain)
![]() ![]() ![]() ![]() 开集极电路(英语:Open Collector,俗称“集电极开路门”或“OC门”),是一种集成电路的输出装置。OC门实际上只是一个NPN型三极管,并不输出某一特定电压值或电流值。OC门根据三极管基极所接的集成电路来决定(三极管发射极接地),通过三极管集电极,使其开路而输出。而输出设备若为场效应晶体管(MOSFET),则称之为漏极开路(英语:Open Drain,俗称“OD门”),工作原理相仿。通过OC门这一装置,能够让逻辑门输出端的直接并联使用。两个OC门的并联,可以实现逻辑与的关系,称为“线与”,但在输出端口应加一个上拉电阻与电源相连。

Open collector 集电极开路(重定向自Open Drain)
![]() ![]() ![]() ![]() An open collector is a common type of output found on many integrated circuits (IC). Instead of outputting a signal of a specific voltage or current, the output signal is applied to the base of an internal NPN transistor whose collector is externalized (open) on a pin of the IC. The emitter of the transistor is connected internally to the ground pin. If the output device is a MOSFET the output is called open drain and it functions in a similar way. |
