Avago Technologies Introduces its Second Series of Hermetically Sealed 3.3V Optocouplers for Aerospace and Military Apps

For designers of applications that operate in harsh environments, the trend is moving towards upgrades and new designs to reduce power consumption that will allow system designers to take advantage of low power components that are now available in the marketplace. Avago’s 3.3V hermetic optocoupler series will help reduce or eliminate the need for extra interface components or voltage converters. Additionally, these low-voltage hermetic optocouplers will help to simplify power supply design, and reduce board space, as well as cost for manufacturers.

Each channel of Avago’s new ACPL-570xL/-573xL/-177xL hermetically sealed optocouplers contains a GaAsP light emitting diode which is optically coupled to an integrated high gain photon detector. In addition, the high gain output stage features open collector output providing both lower saturation voltage and higher signal speed than is possible with conventional photo-Darlington optocouplers. The supply voltage for these new optocouplers from Avago can be operated at as low as 3.0 V without adversely affecting parametric performance.
