IXYS Integrated Circuits Division's LAA108 is
a 100V, 300mA, 8 dual single-pole, normally
open (1-Form-A) Solid State Relay that has two
independently controlled, optically coupled outputs.
The output MOSFET switches and photovoltaic die
employ optically coupled MOSFET technology to
provide 3750 Vrms of input-to-output isolation.

Features
• 3750Vrms Input/Output Isolation
• Low Drive Power Requirements
(TTL/CMOS Compatible)
• Higher Reliability than Electromechanical Relays
• FCC Compatible
• VDE Compatible
• No EMI/RFI Generation
• Small 8-Pin Package
• Machine Insertable, Wave Solderable
• Surface Mount Tape & Reel Versions Available
The relay outputs, that use patented OptoMOS
architecture, are controlled by a highly efficient
infrared LED.
This dual single-pole OptoMOS relay provides a more
compact design solution than two discrete
single-pole relays in a variety of applications, saving
board space by incorporating both switches in a single
8-Pin package.
