TLP521-4 TLP521 Quad PhotoCoupler OptoCoupler DIP-16

Product details of TLP521-4 TLP521 Quad PhotoCoupler OptoCoupler DIP-16
An OptoCoupler (also called optoisolator) is a semiconductor device that allows an electrical signal to be transmitted between two isolated circuits. Two parts are used in an OptoCoupler: an LED that emits infrared light and a photosensitive device that detects light from the LED. Both parts are contained within a black box with pins for connectivity. The input circuit takes the incoming signal, whether the signal is AC or DC, and uses the signal to turn on the LED.
