Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The ISOS141-SEP radiation resistant device is a high performance four channel digital isolator in a small 16-pin QSOP package. The logic input and output buffers of each isolated channel are isolated by a dual capacitive silicon dioxide (SiO2) insulating gate. The ISOS141-SEP device has three forward channels and one reverse channel, with a default output of low if input power or signal is lost. The enable pin can be used to place each output at high impedance for multi-master drive applications and also to reduce power consumption. 

The ISOS141-SEP offers high EMI immunity and low radiation and low power consumption when isolating CMOS or LVCMOS digital I/O. With a high common mode transient immunity of 100kV/µs, the device easily mitigates system level ESD, EFT and surge issues, and also simplifies radiation compliance through an innovative chip design.

• 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.
