DESCRIPTION
The
FTO-1221U
contains a gallium aluminum arsenide LED optically coupled to a silicon planar phototransistor. The
optocoupler is built in a 4 pin leadless chip carrier. This optocoupler is capable of transmitting signals between two
galvanic sources. The potential difference between transmitter and receiver should not go over the maximum isolation
voltage. The internal base connection has been eliminated for improved noise immunity.
