PRODUCTION DATA
The device is a high-performance, quad-channel digital isolator with integrated high efficiency transformer driver. Typically digital isolators require two power supplies isolated from each other to power up both sides of device. Due to integrated transformer driver, with external transformer, the isolated supply can be generated to power the isolated side of the device and peripherals on isolated side, thus saving board space without compromising on efficiency. The voltage range is from 2.25V to 5.5V for both supplies, VCC1 and VCC2. When designing with digital isolators, keep in mind that because of the single-ended design structure, digital isolators do not conform to any specific interface standard and are only intended for isolating single-ended CMOS or TTL digital signal lines. The isolator is typically placed between the data controller (that is, μC or UART), and a data converter or a line transceiver, regardless of the interface type or standard.
The device is designed for applications that have limited board space and desire more integration. The device is also designed for very high voltage applications with power transformer supporting high voltage isolation.
