Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ISO7220CDR devices are dual-channel digital isolators. For ease of PCB layout, the channels are orientated in the same direction in the ISO7220x and in opposite directions in the ISO7221x. These devices have logic input and output buffers that are isolated by TI's Silicon Dioxide (SiO2) barrier, providing VDE-compliant galvanic isolation up to 4000VPK. When used with isolated power supplies, these devices block high voltages and isolated grounds, and prevent noise currents on data buses or other circuits from going to local ground or interfering with or damaging sensitive circuits.

The binary input signal is conditioned and converted to a balanced signal, which is then differentiated by an isolation layer. Across this isolation layer, the differential comparator can receive logic conversion information and then set or reset the flip-flop and output circuitry accordingly. The circuit will send periodic update pulses across the isolation layer to verify that the DC output level is normal. If this DC refresh pulse is not received every 4µs, the input is considered to be unpowered or not actively driven, and the fail-safe circuitry will drive the output to a logic high state.

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?

  A: the delivery date is marked in most commodity information. You can estimate the delivery time of the commodity according to the delivery date. The specific arrival time depends on the warehouse where the commodity is located and the logistics mode you choose.

• 6.Can the company issue an invoice?

  A: you can issue ordinary invoices for individual users or special VAT invoices for enterprise users.
