Digital optocoupler range expands

Multichannel optocouplers allow designers to reduce parts count, board space and system costs in a wide range of applications.

Avago Technologies has expanded its industry-first family of 3.3V, 15Mbaud, multichannel and bidirectional digital optocouplers in compact (9.9 x 5.9 x 1.7mm), 16-pin thin SOIC packages.

The Avago ACSL-6xx0 series optocouplers allow designers to reduce parts count, board space and system costs in a wide range of applications by replacing one- and two-channel digital optocouplers with a smaller, more compact solution.

Popular applications include network bus isolation in Profibus, DeviceNet and CANbus systems.

Other key digital applications include Inter-Integrated Circuit (I2C) bus isolation, which comprises PoE (power-over-Ethernet), power system management and I2C long-distance transmission.

Avago's previously released ACSL-6210 and ACSL-6410 optocouplers are successful in medical systems where they isolate address lines between the microprocessor and the system interface.

The new ACSL-6xx0 series extends the range of multichannel and bidirectional digital optocouplers offered by Avago Technologies.

The new digital optocouplers are: the ACSL-6300 with triple unidirectional channels; the ACSL-6310 with triple bidirectional (2/1) channels; and the ACSL-6420 with quad bidirectional (2/2) channels.

Avago's patented manufacturing technology for stacking LEDs provided the integration breakthrough necessary to develop multichannel optocouplers.

The integration of multiple optocouplers is achieved through stacking LED die and an insulating layer on a silicon substrate.

"Avago continues to innovate with breakthrough products for the isolation market", said Chong Tze Siong, Vice President and General Manager for Avago Technologies' Optical Communication Solutions Division.

"Our new ACSL family helps customers improve their end-product designs and reduce costs".

"As the world's largest supplier of photo-IC optocouplers, Avago is equipped to provide an entire family of multi-channel optocouplers, in virtually any quantity, with short lead times".

Avago's ACSL-6xx0 series optocouplers perform at a typical operating speed of 15Mbaud.

These devices exhibit high common-mode rejection of 10kV/us minimum and operate from 3.0 to 5.5V supply voltages with an operating temperature range of -40 to +100C.

They are designed to meet the most widely accepted international safety regulations: UL1577 (2500V RMS), CSA Component Acceptance Notice No 5, and IEC/EN/DIN EN60747-5-2.

The Avago ACSL-6xx0 multi-channel optocouplers are available now through Avago Technologies' direct sales channel and worldwide distribution partners.
