1. Describe

ISO774x-Q1 automotive equipment is a high-performance, four-channel digital isolator with 5700 VRMS (DWW package), 5000 VRMS (DW package), and 3000 VRMS (DBQ package) isolation ratings, complying with UL 1577. This series of equipment has reinforced insulation Ratings are based on VDE, CSA, TUV and CQC. ISO774x-Q1 devices provide high Low electromagnetic immunity and low radiation Power consumption, while isolating CMOS or LVCMOS digital I/O. Each isolation channel has one Logical input and output buffers are separated by double bytes Capacitive silicon dioxide (SiO2) insulation barrier. These devices have enable pins that can Used to put the corresponding output in high impedance For multi-master driving applications and reduce energy consumption. The ISO7740-Q1 device has all Four channels in the same direction, ISO7741-Q1 The device has three forward and one reverse Channels, while the ISO7742-Q1 device has two Forward and two reverse channels.

2. Description continued

These devices are used in combination with isolated power supplies to help prevent noise currents on data buses (such as CAN and LIN) or other circuits from entering the local ground and interfering with or Damage to sensitive circuits. Through innovative chip design and layout technology, the electromagnetic compatibility of ISO774x-Q1 devices has been significantly enhanced to simplify system-level ESD, EFT, surge and radiation compliance. ISO774x-Q1 devices are available in 16-pin wide SOIC (DW) and QSOP (DBQ) packages. ISO7741-Q1 is also available in an ultra-wide SOIC (DWW) package.
