3 Description
The ISO774x-Q1 devices are high-performance,
quad-channel digital isolators with 5000 VRMS (DW
package) and 3000 VRMS (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.
