Quad optocoupler goes both ways

Avago Technologies has expanded its industry-first family of 3.3V multichannel and bidirectional digital optocouplers to include a bidirectional quad version.

Avago Technologies has expanded its industry-first family of 3.3V multichannel and bidirectional digital optocouplers to include a bidirectional quad version.

The Avago ACSL-6410 allows customers to reduce parts count, board space and system costs in a wide range of consumer, computing, communications and industrial applications.

It features three forward channels and one reverse channel in a compact (9.9 x 5.9 x 1.7mm), 16-pin thin SOIC package.

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's ACSL-6410 multichannel optocoupler is an excellent choice for a wide range of multidirectional or bidirectional applications: computer parallel interfaces and serial interfaces such as RS232/485/422, SPI and I2C bus; microprocessor system interfaces; digital isolation for A/D and D/A convertors; data acquisition; and full-duplex communications.

"Avago plans to expand the ACSL family with additional unidirectional and bidirectional channel combinations", said Chong Tze Siong, Vice President and General Manager for Avago Technologies' Optical Communication Solutions Division.

"These different channel configurations will enable ease of design and cost savings".

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 EN 60747-5-2.

The Avago ACSL-6410 quad-channel bidirectional optocoupler is available now through Avago Technologies' direct sales channel and worldwide distribution partners.
