集电极开路 Open collector

(重定向自Open Drain)
一个集成电路(IC)开集级电路的简化图
A simple schematic of an open collector of an integrated circuit (IC).
Pseudo Open Drain usage in DDR interfaces.

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)

Pseudo Open Drain usage in DDR interfaces.
一个集成电路(IC)开集级电路的简化图

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.
