WebOct 4, 2024 · Are encoders PNP or NPN? Open Collector Encoder Output Open-collector output drivers are based on NPN transistors. When the transistor is on, the encoder acts as a current sink. Is RS422 TTL? TTL provides an RS422 output signal level, which will be +5VDC when active (on) regardless of the supply voltage level. WebJul 16, 2024 · A current flowing into the base of the NPN turns on the transistor whereas a current flowing out of the base turns on the PNP. Thus the most common use for NPN devices is for switching the ground side of a circuit. PNP devices are used to switch from the positive side. For example, consider the simple case of a load and and a voltage source.
