Avago Technologies announces extended-temperature digital optocouplers

Avago Technologies has announced its ACPL-M49U ACPL-K49U, ACPL-M71U, and ACPL-M72U digital optocouplers, which are new additions to its R²Coupler family. These optocouplers provide a wider offering of extended-temperature-range digital optocouplers to the existing family and are designed to meet customer needs for low power, low leakage, higher isolation voltage, and higher CMR (common-mode rejection). Avago Technologies' extended-operating-temperature digital optocouplers are increasingly used in a wide variety of isolation applications including power-supply, computing, factory-automation, data-communications, and digital-logic-interface circuits. These new digital optocouplers—the ACPL-M49U, -K49U, -M71U, and -M72U—ensure the AC and DC performances over the extended temperature range of -40 to +125°C. The ACPL-M71U and -M72U devices are high speed, low power digital optocouplers with R²Coupler isolation and a low current draw of 1.5 mA. The ACPL-M71U uses a high-speed LED to achieve 35-ns maximum propagation delay, while the ACPL-M72U uses a low current LED for lower power consumption. The ACPL-M49U and -K49U are low speed, high CMR digital optocouplers, both configurable as low power and low leakage optocouplers. The ACPL-M49U, -M71U, and -M72U are single-channel optocouplers in SO5 packages. The ACPL-K49U is a single-channel optocoupler in an SO8 package. All new optocouplers are compliant to industrial safety standards such as IEC/EN/DIN EN 60747-5-5 approval for reinforced insulation, UL 1577 and CSA. R²Coupler isolation provides the reinforced insulation and reliability that delivers safe signal isolation that is critical in high temperature industrial applications. Samples and production quantities are available now. Avago Technologies Product deeplink
