Broadcom ACSL-7210 Optocoupler

Broadcom ACSL-7210 Optocoupler is a dual-channel bidirectional 25MBd digital optocoupler utilizing CMOS IC technology and patented packaging technologies to achieve high isolation voltage 3750VRMS in a <2mm low profile narrow-body SOIC-8 package. The device optimizes for bidirectional industrial communication networks such as Fieldbus (PROFIBUS) and Serial Peripheral Interface (SPI) applications. The main building blocks of the ACSL-7210 for each channel are a CMOS LED driver IC that is controlled by a CMOS logic input signal, a high speed LED, and a CMOS detector IC. These building blocks allow fast propagation delay of 40 ns and short pulse width distortion of 10 ns maximum. The ACSL-7210 has common-mode noise immunity of typical 35 kV/µs at 1000 VCM, with UL recognized with isolation voltage of 3750 VRMS for 1 minute, and IEC/EN/ DIN EN 60747-5-5 working insulation voltage VIORM of 567 VPEAK with reinforced insulation.
