open (1-Form-A) relay and one single-pole, normally
closed (1-Form-B) relay), in an 8-pin package that
employs optically coupled MOSFET technology to
provide 3750V
rms
of input to output isolation.
The optically coupled relay outputs, which use the
patented OptoMOS architecture, are controlled by a
highly efficient GaAIAs infrared LED.
LBA127L is designed to provide an ideal solution
where a complementary Form-A/Form-B relay pair is
required in a space-saving single package.
