The output MOSFET switches and photovoltaic die employ optically coupled MOSFET technology to provide 3750 Vrms of input-to-output isolation. The relay outputs, that use patented OptoMOS architecture, are controlled by a highly efficient infrared LED. This dual pole OptoMOS relay provides a more compact design solution than discrete single-pole relays in a variety of applications, and saves board space by incorporating both switches in a single 8-Pin package. ## **Approvals** - UL Recognized Component: File # E76270 - CSA Certified Component: Certificate # 1175739 - TUV EN 62368-1: Certificate # B 082667 0008 - Hook Switch - Dial Pulsing - Ground Start - Ringing Injection - Instrumentation - Multiplexers - Data Acquisition - Electronic Switching - I/O Subsystems ## **Ordering Information** |**Part #**|**Description**| |---|---| |LAA110|8-Pin DIP (50/Tube)| |LAA110S|8-Pin Surface Mount (50/Tube)| |LAA110STR|8-Pin Surface Mount (1,000/Reel)| |LAA110P|8-Pin Flat Pack (50/Tube)| |LAA110PTR|8-Pin Flat Pack (1,000/Reel)| - Meters (Watt-Hour, Water, Gas) - Medical Equipment-Patient/Equipment Isolation - Security - Industrial Controls ## **Pin Configuration** |||||1|1||||||8||||| |---|---|---|---|---|---|---|---|---|---|---|---|---|---|---|---| |+ Control - Switch #1|+ Control - Switch #1|+ Control - Switch #1|+ Control - Switch #1|||||||||Load - Switch #1|Load - Switch #1|Load - Switch #1|Load - Switch #1| |||||2|||||||7||||| |– Control - Switch #1|– Control - Switch #1|– Control - Switch #1|– Control - Switch #1|||||||||Load - Switch #1|Load - Switch #1|Load - Switch #1|Load - Switch #1| |||||3|||||||6||||| |+ Control - Switch #2

R12 **www.ixysic.com** **4** **LAA110** INTEGRATED CIRCUITS DIVISION ## **Manufacturing Information** ## **Moisture Sensitivity** All plastic encapsulated semiconductor packages are susceptible to moisture ingression. IXYS Integrated Circuits classifies its plastic encapsulated devices for moisture sensitivity according to the latest version of ¢) the joint industry standard, **IPC/JEDEC J-STD-020** , in force at the time of product evaluation. We test all of our products to the maximum conditions set forth in the standard, and guarantee proper operation of our devices when handled according to the limitations and information in that standard as well as to any limitations set forth in the information or standards referenced below. Failure to adhere to the warnings or limitations as established by the listed specifications could result in reduced product performance, reduction of operable life, and/or reduction of overall reliability. This product carries a **Moisture Sensitivity Level (MSL)** classification as shown below, and should be handled according to the requirements of the latest version of the joint industry standard **IPC/JEDEC J-STD-033** . |**Device**

~~——~~| ## **Board Wash** IXYS Integrated Circuits recommends the use of no-clean flux formulations. Board washing to reduce or remove flux residue following the solder reflow process is acceptable provided proper precautions are taken to prevent damage to the device. These precautions include but are not limited to: using a low pressure wash and providing a follow up bake cycle sufficient to remove any moisture trapped within the device due to the washing process. Due to the variability of the wash parameters used to clean the board, determination of the bake temperature and duration necessary to remove the moisture trapped within the package is the responsibility of the user (assembler). Cleaning or drying methods that employ ultrasonic energy may damage the device and should not be used. Additionally, the device must not be exposed to halide flux or solvents. **www.ixysic.com** R12 **5** **LAA110** INTEGRATED CIRCUITS DIVISION ## **MECHANICAL DIMENSIONS** **==> picture [421 x 186] intentionally omitted <==** **----- Start of picture text -----**
