ACTIVE
Quad-channel, 3/1, 25-Mbps digital isolatorThe ISO7240x, ISO7241x, and ISO7242x devices are quad-channel digital isolators withmultiple channel configurations and output-enable functions. These devices have logic-input andlogic-output buffers separated by Texas Instrument’s silicon-dioxide (SiO2)isolation barrier. Used in conjunction with isolated power supplies, these devices help block highvoltage, isolate grounds, and prevent noise currents from entering the local ground and interferingwith or damaging sensitive circuitry.
The ISO7240x family of devices has all four channels in the same direction. The ISO7241xfamily of devices has three channels in the same direction and one channel in the oppositiondirection. The ISO7242x family of devices has two channels in each direction.
The devices with the C suffix (C option) have TTL input thresholds and a noise-filter atthe input that prevents transient pulses from being passed to the output of the device. The deviceswith the M suffix (M option) have CMOS VCC/2 input thresholds and do nothave the input noise filter or the additional propagation delay.
The ISO7240CF device has an input disable function on pin 7, and a selectable high or lowfailsafe-output function with the CTRL pin (pin 10). The failsafe output is a logic high when alogic high is placed on the CTRL pin or it is left unconnected. If a logic low signal is applied tothe CTRL pin, the failsafe output becomes a logic-low output state. The input disable function ofthe ISO7240CF device prevents data from being passed across the isolation barrier to the output.When the inputs are disabled or VCC1 is powered down, the outputs are set bythe CTRL pin.
These devices can be powered from 3.3-V or 5-V supplies on either side, in anycombination. The signal input pins are 5-V tolerant regardless of the voltage supply level that isused.
These devices are characterized for operation over the ambient temperature range of –40°Cto +125°C.

ISO7341CDWR SOP-16 Electronic components integrated circuit Digital isolator
ISO7341CDWR Low-power, quad-channel, 3/1, 25-Mbps digital isolator
The ISO734x family of devices provides galvanic isolation up to 3000 VRMS for 1 minute per UL 1577 and 4242 VPK per 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.
The ISO7340x device has four channels in forward direction, the ISO7341x device has three forward and one reverse-direction channels, and the ISO7342x device has two forward and two reverse-direction channels. In case of input power or signal loss, the default output is for devices with suffix and for devices without suffix . See the section for further details.
Used in conjunction with isolated power supplies, these devices help prevent noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry. The ISO734x device has integrated noise filter for harsh industrial environment where short noise pulses may be present at the device input pins. The ISO734x device has TTL input thresholds and operates from 3-V to 5.5-V supply levels. Through innovative chip design and layout techniques, electromagnetic compatibility of the ISO734x family of devices has been significantly enhanced to enable system-level ESD, EFT, surge, and emissions compliance.
