8.1 Application Information

The ISO672x-Q1 devices are high-performance, dual-channel digital isolators. The devices use single-ended CMOS-logic switching technology. The supply voltage range is from 1.71V to 5.5V for both supplies, VCC1 and VCC2. Since an isolation barrier separates the two sides, each side can be sourced independently with any voltage within recommended operating conditions. As an example, supplying ISO672x-Q1 VCC1 with 3.3V (which is within 1.71V to 1.89V and 2.25V to 5V) and VCC2 with 5V (which is also within 1.71V to 1.89V and 2.25V to 5V) is possible. You can use the digital isolator as a logic-level translator in addition to providing isolation. 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, MCU or FPGA), and a data converter or a line transceiver, regardless of the interface type or standard.
