Switched dc output vs open collector
Splet03. mar. 2016 · It seems the difference between open collector and push and pull is one is float and the other is not. Here I am not quite clear with the concept “ float” . The article #2 said for the open collector circuit, when in the off state, an open collector will float. But I think in the on state, push and pull will also float. Splet18. avg. 2016 · The main difference is that on open collector outputs you will see no output voltage when in high state. The output voltage must be provided by the load, i.e. usually the load is connected between Vcc (usually 5.0 or 3.3VDC) and the output, and the load (a solenoid for example) will be activated when the output is in low state.

Splet10. maj 2024 · The two transistors used drives a high output and another pulls it down in an Integrated circuit. 2. Open collector : In case of open collector we only have pull down transistor and it operates at slow speed. Open collector behaves like a switch in which it is either connected or disconnected in an Integrated circuit. Splet01. sep. 2024 · Using a Schottky clamp on the phototransistor’s open collector output can provide relatively good linearity in the device’s response. ... The triac optoisolator can safely operate a high-voltage AC supply from a simple switched DC input. Unlike photo-SCRs, a triac optoisolator can operate across the entire mains AC cycle with zero-crossing ...
