3 Description

The ISO676x devices are high-performance, six-

channel digital isolators ideal for cost-sensitive

applications requiring up to 5000 VRMS isolation

ratings per UL 1577. These devices are also certified

by VDE, TUV, CSA, and CQC.

The ISO676x devices provide high electromagnetic

immunity

and

low

emissions

at

low

power

consumption, while isolating CMOS or LVCMOS

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

and output buffer separated by TI's double capacitive

silicon dioxide (SiO2) insulation barrier. The ISO676x

family of devices is available in all possible pin

configurations such that all six channels are in the

same direction, or one, two, or three channels are in

reverse direction while the remaining channels are in

forward direction. In the event of input power or signal

loss, the default output is high for devices without

suffix F and low for devices with suffix F. See Device

Functional Modes section for further details.

Used in conjunction with isolated power supplies,

these devices help prevent noise currents on data

buses, such as UART, SPI, RS-485, RS-232, and

CAN from damaging sensitive circuitry. Through

innovative chip design and layout techniques, the

electromagnetic compatibility of the ISO676x devices

has been significantly enhanced to ease system-level

ESD, EFT, surge, and emissions compliance. The

ISO676x family of devices is available in a 16-pin

SOIC wide-body (DW) package and is a pin-to-pin

upgrade to the older generations.
