Avago Technologies Extends its R2Coupler Family with Operating Temperature Digital Optocouplers

Avago Technologies announced that it has extended its R2CouplerTM family with ACPL-M49U/K49U/M71U/M72U digital optocouplers. 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 common-mode rejection (CMR).

R2Coupler isolation provides the reinforced insulation and reliability that delivers safe signal isolation that is critical in high temperature industrial applications.

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. The optocouplers ensure the AC and DC performances over the extended temperature range of –40°C to +125°C. The ACPL-M71U/M72U devices are high speed, low power digital optocouplers with R2Coupler isolation and a low power consumption of 1.5mA.

The ACPL-M71U uses a high-speed LED to achieve 35ns maximum propagation delay, while the ACPL-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 optocouplers. An internal shield also ensures a CMR of typical 30 kV/µs at 1500V common-mode voltage.

Avago Technologies is a supplier of analog interface components for wireless, wireline, and industrial applications and its extended operating temperature digital optocouplers are increasingly used in a wide variety of isolation applications ranging from power supply, computing, factory automation, data communications and digital logic interface circuits.

The ACPL-M49U and ACPL-K49U are immediately available in sample quantities, and will sell for USD 1.13 apiece and USD 1.25 apiece in lots of 10k units respectively. The ACPL-M71U and ACPL-M72U are immediately available in sample quantities, and will sell for USD 1.75 a piece in lots of 10k units. Samples and production quantities are available now through the Avago direct sales channel and via worldwide distribution partners.

Avago Technologies Limited is expected to report its fourth quarter and fiscal year 2012 financial results and business outlook on Thursday, November 29, 2012 after the close of the market. Avago's management will host a conference call at 2:00 p.m. Pacific Time on the same day to discuss these results and business outlook.
