PRODUCTION DATA
The ISO652x devices are high-performance, dual-channel digital isolators. The devices use single-ended CMOS-logic switching technology. The supply voltage range is from 1.71 V to 5.5 V for both supplies, VCC1 and VCC2. Since an isolation barrier separates the two sides, each side can be sourced independently with any voltage within the recommended operating conditions. As an example, supplying VCC1 with 3.3 V (which is within 1.71 V to 1.89 V and 2.25 V to 5 V) and VCC2 with 5 V (which is also within 1.71 V to 1.89 V and 2.25 V to 5 V) is possible. The digital isolator can be used 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.
