Multichannel optocouplers now in thin SOIC package

8 March 2006 Opto-Electronics

Avago Technologies has expanded its family of 3,3 V, 15 MBd, multichannel and bi-directional digital optocouplers with the ACSL-6xx0 series in a compact 9,9 x 5,9 x 1,7 mm, 16-pin thin SOIC package. These 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 CAN bus 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 include: ACSL-6300 with triple unidirectional channels; ACSL-6310 with triple bi-directional (2/1) channels; ACSL-6420 with quad bi-directional (2/2) channels.

Typical operating speed for the ACSL-6xx0 series is 15 MBd. They exhibit high common-mode rejection of 10 kV/μs minimum and operate from 3,0 V to 5,5 V within -40 to +100°C. They meet safety regulations: UL1577 (2500 V rms), CSA, and IEC/EN/DIN EN 60747-5-2.
