3 Description

The ISO7710 device is a high-performance, single-

channel digital isolator with 5000VRMS (DW package)

and 3000VRMS (D package) isolation ratings per UL

1577. This device is also certified by VDE, TUV, CSA,

and CQC.

The ISO7710 device provides high electromagnetic

immunity

and

low

emissions

at

low

power

consumption, while isolating CMOS or LVCMOS

digital I/Os. The isolation channel has a logic input

and output buffer separated by a double capacitive

silicon dioxide (SiO2) insulation barrier. In the event

of input power or signal loss, default output is high

for a device without suffix F and low for a device with

suffix F. See the Device Functional Modes section for

further details.

Used in conjunction with isolated power supplies, the

device helps prevent noise currents on data buses,

such as RS-485, RS-232, and CAN , or other circuits

from entering the local ground and interfering with or

damaging sensitive circuitry. Through innovative chip

design and layout techniques, the electromagnetic

compatibility of the ISO7710 device has been

significantly enhanced to ease system-level ESD,

EFT, surge, and emissions compliance. The ISO7710

device is available in 16-pin SOIC wide-body (DW)

and 8-pin SOIC narrow-body (D) packages.
