opendrainopencollectortyyppisiä
Opendrainopencollectortyyppisiä refers to a type of electronic output stage commonly found in integrated circuits. The term itself is a combination of "open-drain" and "open-collector," which describe the fundamental behavior of the output transistor. In this configuration, the output transistor is not directly connected to a power supply rail (like Vcc or Vdd) or ground. Instead, one end of the transistor is connected to the output pin, and the other end is left "open" or connected to either the power supply or ground through an external component, typically a pull-up or pull-down resistor.
When the output transistor is turned on, it connects the output pin to either ground (in the
The primary advantage of opendrain/opencollector outputs is their flexibility. They allow multiple devices with such outputs
