3 Description
The ISO774x-Q1 devices are high-performance,
quad-channel digital isolators with 5000 V_RMS (DW
package) and 2500 V_RMS (DBQ package) isolation
ratings per UL 1577. This family of devices has
reinforced insulation ratings according to VDE, CSA,
TUV and CQC.
The ISO774x-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 silicon
dioxide (SiO₂) insulation barrier. This device 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. The ISO7740-Q1 device has all four
channels in the same direction, the ISO7741-Q1
device has three forward and one reverse-direction
channels, and the ISO7742-Q1 device has two
forward and two reverse-direction channels. If the
input power or signal is lost, default output is high for
devices without suffix F and low for devices with
suffix F. See the Device Functional Modes section for
further details.
Used in conjunction with isolated power supplies, this
device helps prevent 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 the
ISO774x-Q1 devices have been significantly
enhanced to ease system-level ESD, EFT, surge, and
emissions compliance. The ISO774x-Q1 devices are
available in 16-pin SOIC and QSOP packages.
