WETZLAR, Germany, Dec. 27, 2012 — Avago Technologies has announced extended-operating-temperature digital optocouplers with R2Coupler Isolation. The compact devices operate with low power, low leakage, high isolation voltage and high common-mode rejection (CMR). The ACPL-M49U/K49U/M71U/M72U are used in a variety of isolation applications ranging from power supply, computing, factory automation, data communications and digital logic interface circuits. They ensure AC and DC performance over the extended temperature range of −40 to 125 °C. The ACPL-M71U/M72U devices consume 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. An internal shield ensures a typical CMR of 30 kV/µs at 1500-V common-mode voltage. The ACPL-M49U, ACPL-M71U and ACPL-M72U are single-channel optocouplers in five-lead small-outline (SO5) packages; the ACPL-K49U is a single-channel optocoupler in an eight-lead small-outline (SO8) package. All are compliant with industrial safety standards. R2Coupler isolation provides the reinforced insulation and reliability that deliver safe signal isolation, critical in high-temperature industrial applications.
