![]() Opto-isolators prevent high voltages from affecting the system receiving the signal. Both CA-IS3741 and CA-IS3742 come with individual enable control pins for each side of the isolator which can be used to put the outputs in high impedance for multi-master driving applications to reduce power consumption. Ranging from dual channel to quad channel, Si86xxT isolators are available in wide body packages to accommodate the higher isolation rating associated with. An opto-isolator (also called an optocoupler, photocoupler, or optical isolator) is an electronic component that transfers electrical signals between two isolated circuits by using light. The CA-IS3742 provides further design flexibility with two channels in each direction. The CA-IS3741 device has three forward and one reverse-direction channel, making it ideal for applications such as isolated SPI, and RS-485 communication. Available in different isolation ratings: 2.5kVrms & 5kVrms are most common. Insulating polymers and inorganic materials are used in high-voltage electronic devices, such as thin film capacitors, gate dielectrics, and digital isolators. Galvanic isolation separates the high voltage from the low voltage domains in a vehicle and is critical to ensuring the safety and operation of modern, high voltage vehicle systems. The CA-IS3740 features 4 channels transferring digital signals in one direction and the output enabled for the B side is active-high. Digital isolators are a buffer for digital signals that provide protection from high voltages and noise. Infineon Technologies AG recently introduced the first generation of its ISOFACE dual-channel digital isolators, which are designed for robust high-voltage. The CA-IS374x family offers all possible unidirectional channel configurations to accommodate any 4-channel design. Each isolation channel has a logic input and output buffer separated by a capacitive silicon dioxide (SiO2) insulation barrier, the integrated Schmitt trigger on each input provides excellent noise immunity in automotive applications. ![]() ![]() The CA-IS374x devices offer high electromagnetic immunity and low emissions at low power consumption while isolating different ground domains and blocking high-voltage/high-current transients from sensitive or human interface circuitry. The CA-IS374x devices are high-performance four-channel, unidirectional digital isolators with up to 5kVRMS wide-body package isolation rating and DC to 150Mbps ultra-fast data rate. ![]()
