Description
LBB127 is a 250V, 200mA, 10 ?? dual normally closed
(1-Form-B) Solid State Relay that comprises two
independently controlled, optically coupled MOSFET
switches. It is provided in an 8-pin package, and
employs optically coupled MOSFET technology to
Features
? 3750V rms Input/Output Isolation
? Low Drive Power Requirements (TTL/CMOS
Compatible)
? High Reliability
? Arc-Free With No Snubbing Circuits
? FCC Compatible
? VDE Compatible
? No EMI/RFI Generation
? Small 8-Pin Package
? Machine Insertable, Wave Solderable
? Surface Mount Tape & Reel Versions Available
Applications
? Telecommunications
? Telecom Switching
? Tip/Ring Circuits
? Modem Switching (Laptop, Notebook, Pocket Size)
? Hook Switch
provide 3750V rms of input to output isolation.
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
This dual single-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.
