JAJSKK3B December 2019 – February 2023 ISO6731
PRODUCTION DATA
The ISO6731 device is a high-performance, triple-channel digital isolators. This device comes with enable pins on each side which can be used to put the respective outputs in high impedance for multi master driving applications. The ISO6731 device uses 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 recommended operating conditions. As an example, it is possible to supply ISO6731 VCC1 with 3.3 V (which is within 1.71 V to 5.5 V) and VCC2 with 5V (which is also within 1.71 V to 5.5 V). 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.
