Frequently asked questions
What is the price of TLP781 Optocoupler Phototransistor Output DIP-4 in Egypt?
TLP781 Optocoupler Phototransistor Output DIP-4 currently costs 12 EGP in Egypt.
Where can I buy TLP781 Optocoupler Phototransistor Output DIP-4 in Egypt?
TLP781 Optocoupler Phototransistor Output DIP-4 is available from Makers Electronics. Compare the offers above to find the best price.
How do I interface it with a microcontroller input?
Drive the LED side through a series resistor from the control supply. Pull the phototransistor collector up to the logic supply with a resistor; the output goes low when the LED conducts.
What does the isolation rating mean?
The 5000 Vrms rating applies between the LED input side and the transistor output side. It does not make the whole circuit safe for mains voltage; creepage, clearance and insulation design still matter.
