Avago Technologies announced new additions to its R2Coupler family in the form of the ACPL-M49U/K49U/M71U/M72U digital optocouplers. The new parts provide a wider temperature range than existing options and are designed to meet customer needs for low power, low leakage, high isolation voltage and high common-mode rejection (CMR).
The ACPL-M71U/M72U devices are high-speed digital optocouplers with R2Coupler isolation and a low power consumption of 1,5 mA. The M71U uses a high-speed LED to achieve 35 ns maximum propagation delay, while the M72U uses a low-current LED for lower power consumption.
The ACPL-M49U/K49U are low-speed, high-CMR digital optocouplers, both configurable as low-power and low-leakage devices. An internal shield also 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 5-lead small-outline (SO5) packages. The ACPL-K49U is a single-channel optocoupler in an 8-lead small-outline (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. They ensure AC and DC performance over the extended temperature range of –40°C to +125°C.
The devices are targeted at a wide variety of isolation applications including power supply, computing, factory automation, data communications and digital logic interface circuits.
