Web開集極電路（英語： Open Collector ，俗稱「集電極開路門」或「OC門」），是一種積體電路的輸出裝置。 OC門實際上只是一個NPN型三極體，並不輸出某一特定電壓值或電流值。 OC門根據三極體基極所接的積體電路來決定（三極體發射極接地），通過三極體集電極，使其開路而輸出。 WebThe devices mentioned in chapter Relevant Devices feature open-drain functionality. Both the open-drain and the open-collector circuit are capable of having the line pulled low by another device and pulling the line low itself; the difference is that open-collector uses a BJT transistor to pull the line low, while open-drain does so by using a ...

This is the “open collector.”. When a logical input to the SN7407N is low, the output of the NOT gate is high, so the base of the transistor is held at a voltage above the emitter. This “turns on” the transistor, which ... flowers near jamison pa https://foodmann.com

WebThe I2C bus transmits data and clock with SDA and SCL. The first thing to realize: SDA and SCL are open-drain (also known as open-collector in the TTL world), that is I2C master and slave devices can only drive these lines low or leave them open. The termination resistor Rp pulls the line up to Vcc if no I2C device is pulling it down.

Open Collector Outputs - Basic Electronics Tutorials

WebTutorial Summary. We have seen here in this tutorial about the open collector output that it can provide a current sink or current source output depending on the type of bipolar transistor, NPN-type or PNP-type, used. When an NPN-type transistor is in its “ON” state, it will provide or “sink” a path to ground. WebThe TLV3011 is a low-power, open-drain output comparator;the TLV3012 is a push-pull output comparator. Both feature an uncommitted on-chip voltage reference. Both have 5µA (max) quiescent current, input common-mode range 200mV beyond the supply rails, and single-supply operation from 1.8V to 5.5V.
