3 Description

•

Signaling Rate: 25 Mbps

The ISO734x-Q1 family of devices provides galvanic

isolation up to 3000 V_RMSfor 1 minute per UL 1577

and 4242 V_PKper VDE V 0884-10. These devices

have four isolated channels comprised of logic input

and output buffers separated by a silicon dioxide

(SiO₂) insulation barrier.

Integrated Noise Filter on the Inputs

Default Output High and Low Options

Low Power Consumption, Typical I_CCper Channel

at 1 Mbps:

–

ISO7340-Q1: 0.9 mA (5-V Supplies),

0.7 mA (3.3-V Supplies)

The ISO7340-Q1 device has four channels in forward

direction, the ISO7341-Q1 device has three forward

and one reverse-direction channels, and the

ISO7342-Q1 device has two forward and two reverse-

direction channels. In case of input power or signal

loss, default output is low for orderable part numbers

with suffix F and high for orderable part numbers

without suffix F. See the Device Functional Modes

section for further details.

ISO7341-Q1: 1.2 mA (5-V Supplies),

0.9 mA (3.3-V Supplies)

ISO7342-Q1: 1.3 mA (5-V Supplies),

0.9 mA (3.3-V Supplies)
