Automotive, High Speed, Robust EMC Quad-Channel Digital Isolators - ISO7740-Q1

ISO7740-Q1 (ACTIVE)

Automotive, High Speed, Robust EMC Quad-Channel Digital Isolators

 

Description

The devices are high-performance, quad-channel digital isolators with 5000 VRMS (DW package) and 2500 VRMS (DBQ package) isolation ratings per UL 1577. This family of devices has reinforced insulation ratings according to VDE, CSA, TUV and CQC.

The devices provide high
electromagnetic immunity and low emissions at low power consumption, while isolating CMOS or LVCMOS digital I/Os. Each isolation channel has a logic input and output buffer separated by silicon dioxide (SiO2) insulation barrier. This device comes with enable pins which can be used to put the respective outputs in high impedance for multi-master driving applications and to reduce power consumption. The device has all four channels in the same direction, the device has three forward and one reverse-direction channels, and the device has two forward and two reverse-direction channels. If the input power or signal is lost, default output is for devices without suffix F and for devices with suffix F. See the section for further details.

Used in conjunction with isolated power supplies, this device helps prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. Through innovative chip design and layout techniques, electromagnetic compatibility of the devices have been significantly enhanced to ease system-level ESD, EFT, surge, and emissions compliance. The devices are available in 16-pin SOIC and QSOP packages.

For all available packages, see the orderable addendum at the end of the data sheet.
