3 Description

The ISO674x-Q1 devices are high-performance,

quad-channel digital isolators designed for costsensitive

applications requiring up to 5000VRMS

isolation ratings per UL 1577. These devices are also

certified by VDE, TUV, CSA, and CQC.

The ISO674x-Q1 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. These devices come with enable pins which

can be used to put the respective outputs in high

impedance for multi-controller driving applications.

The ISO6740-Q1 device has all four channels in the

same direction, the ISO6741-Q1 device has three

forward and one reverse-direction channels, and the

ISO6742-Q1 device has two forward and two reversedirection

channels. 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

also Device Functional Modes section.

Used in conjunction with isolated power supplies,

the ISO674x-Q1 devices help prevent noise currents

on data buses, such as CAN and LIN from

damaging sensitive circuitry. Through remarkable chip

design and layout techniques, the electromagnetic

compatibility of the ISO674x-Q1 devices has been

significantly enhanced to ease system-level ESD,

EFT, surge, and emissions compliance. The ISO674x-

Q1 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.
