5 Description (continued)

Used in conjunction with isolated power supplies, these devices help prevent noise currents on a data bus or

other circuits from entering the local ground and interfering with or damaging sensitive circuitry. The ISO734x

device has integrated noise filter for harsh industrial environment where short noise pulses may be present at the

device input pins. The ISO734x device 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 ISO734x family of

devices has been significantly enhanced to enable system-level ESD, EFT, surge, and emissions compliance.
