Clare's LAA108 is a 100V, 300mA, 8Ω dual
1-Form-A (single-pole normally open)
Solid State Relay that has two independently
controlled, optically coupled outputs.

The output MOSFET switches and photovoltaic die
use Clare’s patented OptoMOS architecture to provide
3750 Vrms of input-to-output isolation. The optically
coupled output is controlled by a highly efficient
GaAIAs infrared LED.
Features
• Small 8-pin Package
• Low Drive Power Requirements (TTL/CMOS
Compatible)
• High Reliability
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.
