Description

General part information

ISO7331-Q1 Series

The ISO733x family of devices provides galvanic isolation up to 3000 VRMSfor 1 minute per UL 1577 and 4242 VPKper VDE V 0884-10. These devices have three isolated channels comprised of logic input and output buffers separated by a silicon dioxide (SiO2) insulation barrier.

The ISO7330 has all three channels in the same direction while ISO7331 has two channels in forward and one channel in reverse direction. See the section for further details.

Used in conjunction with isolated power supplies, these devices prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. The ISO733x family of devices has integrated noise filter for harsh industrial environment where short noise pulses may be present at the device input pins. The ISO733x family of devices has TTL input thresholds and operates from 3-V to 5.5-V supply levels. Through innovative chip design and layout techniques, electromagnetic compatibility of the ISO733x family of devices has been significantly enhanced to enable system-level ESD, EFT, Surge and Emissions compliance.
