Texas Instruments ISO7731DWR
The ISO773x devicesare high-performance, triple-channel digital isolators with 5000 VRMS (DWpackage) and 3000 VRMS (DBQ package) isolation ratings per UL1577.
This family of devices has reinforced insulation ratings according to VDE, CSA, TUV andCQC.
The ISO773x familyof devices provides high electromagnetic immunity and low emissions at low power consumption, whileisolating CMOS or LVCMOS digital I/Os. Each isolation channel has a logic input and output bufferseparated by a silicon dioxide (SiO2) insulation barrier. This device comeswith enable pins which can be used to put the respective outputs in high impedance for multi-masterdriving applications and to reduce power consumption. The ISO7730 device has all threechannels in the same direction and the ISO7731 device has two forward and one reverse-direction channel. If theinput power or signal is lost, the default output is high fordevices without suffix F and low for devices with suffix F. Seethe Device Functional Modes section for furtherdetails.
Used in conjunction with isolated power supplies, this device helps prevent noisecurrents on a data bus or other circuits from entering the local ground and interfering with ordamaging sensitive circuitry. Through innovative chip design and layout techniques, electromagneticcompatibility of the ISO773xdevice has been significantly enhanced to ease system-level ESD, EFT, surge, and emissionscompliance. The ISO773xfamily of devices is available in 16-pin wide-SOIC and QSOP packages.
