Avago's ACSL-6410 optocupler can bring benefits of reduced parts count and board space to fieldbus interfaces and various test and measurement applications.

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.
