Avago Technologies —formerly Agilent Technologies’ Semiconductor Products Group—has expanded its “industry-first” family of 3.3 V, 15 MBd, multi-channel and bi-directional digital optocouplers to include a bi-directional quad version. Avago ACSL-6410 lets users reduce parts count, board space, and system costs in a wide range of consumer, computing, communications, and industrial applications. The optocoupler features three forward channels and one reverse channel in a compact (9.9 x 5.9 x 1.7 mm), 16-pin thin small-outline integrated circuit (SOIC) package.

To develop multi-channel optocouplers, an integration breakthrough was needed. It came by way of Avago's patented manufacturing technology for stacking LEDs and an insulating layer on a silicon substrate. ACSL-6410 optocoupler is suited for various multi- or bi-directional applications:  • Data acquisition; and

  • Full-duplex communications.

Avago's ACSL-6xx0 Series optocouplers typically operate at a speed of 15 MBd. Other features include high common-mode rejection of 10 kV/µs (minimum), operation from 3.0-5.5 V supply, and a working temperature range of–40 to100 ºC. These devices meet widely accepted international safety regulations: UL1577 (2,500 Vrms), CSA Component Acceptance Notice No. 5, and IEC/EN/DIN EN 60747-5-2.

ACSL-6410 quad-channel bi-directional optocoupler is priced at $3.80 each, in 10,000-piece quantities.
