he HCPL-3120 contains a GaAsP LED while the HCPL­­J312 and the HCNW3120 contain an AlGaAs LED. The LED is optically coupled to an integrated circuit with a power output stage. These optocouplers are ideally suited for driving power IGBTs and MOSFETs used in motor control inverter applications. The high operating voltage range of the output stage provides the drive voltages required by gate controlled devices. The voltage and current supplied by these optocouplers make them ideally suited for directly driving IGBTs with ratings up to 1200 V/100 A. For IGBTs with higher ratings, the HCPL-3120 series can be used to drive a discrete power stage which drives the IGBT gate. The HCNW3120 has the highest insulation voltage of VIORM=1414Vpeak in the IEC/EN/DIN EN 60747-5-2. The HCPL-J312 has an insulation voltage of VIORM=891Vpeak and the VIORM=630Vpeak is also available with the HCPL-3120 (Option060).

The HCNR200/201 high-linearity analog optocoupler consists of a high-performance AlGaAs LED that illumi  nates two closely matched photodiodes. The input pho todiode can be used to monitor, and therefore stabilize, the light output of the LED. As a result, the non-linearity and drift characteristics of the LED can be virtually elimi nated. The output photodiode produces a photocurrent that is linearly related to the light output of the LED. The close matching of the photo-diodes and advanced de sign of the package ensure the high linearity and stable gain characteristics of the optocoupler. The HCNR200/201 can be used to isolate analog signals in a wide variety of applications that require good stabil ity, linearity, bandwidth and low cost. The HCNR200/201 is very flexible and, by appropriate design of the appli cation circuit, is capable of operating in many different modes, including: unipolar/bipolar, ac/dc and inverting/ non-inverting. The HCNR200/201 is an excellent solution for many analog isolation problems

The Broadcom® HCPL-22XX, HCPL-02XX, and HCNW22XX are optically coupled logic gates. The HCPL22XX and HCPL-02XX contain a GaAsP LED while the HCNW22XX contains an AlGaAs LED.

The DG408 Single 8-Channel, and DG409 Differential 4-Channel monolithic CMOS analog multiplexers are drop-in replacements for the popular DG508A and DG509A series devices. They each include an array of eight analog switches, a TTL/CMOS compatible digital decode circuit for channel selection, a voltage reference for logic thresholds and an ENABLE input for device selection when several multiplexers are present. The DG408 and DG409 feature lower signal ON resistance (<100) and faster switch transition time (tTRANS < 250ns) compared to the DG508A or DG509A. Charge injection has been reduced, simplifying sample and hold applications. The improvements in the DG408 series are made possible by using a high-voltage silicon-gate process. An epitaxial layer prevents the latch-up associated with older CMOS technologies. Power supplies may be single-ended from +5V to +34V, or split from 5V to 20V. The analog switches are bilateral, equally matched for AC or bidirectional signals. The ON resistance variation with analog signals is quite low over a 5V analog input range. 

The 4N35S-TA1 is an optoisolator or opto-coupler integrated circuit (IC) manufactured by Fairchild Semiconductor (now part of ON Semiconductor). It is designed to provide electrical isolation between two circuits while allowing signal transmission through light. The optocoupler uses an LED to transmit the signal and a phototransistor to receive the signal, ensuring that the two sides of the circuit are electrically isolated from each other. This is useful in protecting sensitive components from voltage spikes or noise from high-voltage circuits.
