3 Description

The ISO7820 is a high-performance, dual-channel

digital isolator with 8000 VPK isolation voltage. This

device has reinforced isolation certifications

according to VDE, CSA, CQC, and TUV. The isolator

provides high electromagnetic immunity and low

emissions at low power consumption, while isolating

CMOS or LVCMOS digital I/O’s. Each isolation

channel has a logic input and output buffer separated

by silicon dioxide (SiO2) insulation barrier. ISO7820

has two forward channels and no reverse-direction

channel. If the input power or signal is lost, default

output is 'high' for the ISO7820 and 'low' for the

ISO7820F device. Used in conjunction with isolated

power supplies, this device prevents 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 ISO7820

has been significantly enhanced to ease system-level

ESD, EFT, Surge and Emissions compliance.

ISO7820 is available in 16-pin SOIC wide-body (DW)

and extra-wide body (DWW) packages. The DWW

package option 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.
