3 Description

The ISO7821 is a high-performance, dual-channel

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

has one forward and one reverse-direction channel. If

the input power or signal is lost, default output is

'high' for the ISO7821 and 'low' for the ISO7821F

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 ISO7821

has been significantly enhanced to ease system-level

ESD,

EFT,

Surge

and

Emissions

compliance.

ISO7821 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.
