• Description: 6-Pin DIP Random-Phase Optoisolators Triac Driver Output
• Manufacturer: Motorola

MOC3021 MOC3022 MOC3023
Additional information on the use of optically coupled triac
drivers is available in Application Note AN–780A.
* This optoisolator should not be used to drive a load directly. It is in-
tended to be a trigger device only.
