Part Number: ISO7340C Other Parts Discussed in Thread: SN74AHCT1G14 Hello Team,
please provide "positive-going input threshold" and "negative-going input threshold voltages" as the blockdiagram in the data sheet show a Schmitt-Trigger. Schmitt-Trigger…
Part Number: ISO7340C Other Parts Discussed in Thread: ISOW7840 Hi,
I am thinking to use TI digital isolator in my design. but I have some questions need to be clarified:
1. I know TI uses capacitor isolation architecture. is the frequency crossing…
Part Number: ISO7330C Other Parts Discussed in Thread: ISO7340C , , ISO7730 Dear Specialists,
My customer is considering ISO7330 instead of ISO7340.
They have a question about NC pin connection, so I would be grateful if you could advise.

Hi Chen,
ISO7740 employs OOK architecture for communication and hence consumes slightly more current compared to ADuM2400 while ADuM2400 uses an older edge-based architecture that is slightly lower powered.
We have ISO7340C that follows similar architecture…
Yes, you can. The 2-wire transmitter is meant to be loop powered and you cannot connect the ground of another supply to the I RET of the transmitter as seen in the diagram below.
If you wish to use a sensor with its own supply and ground, you need…
If you are attempting to use 2-wire transmitters, you will need to isolate the input to each transmitter. The I RET pin of a 2-wire transmitter needs to float and cannot be tied to other grounds or the I RET of other transmitters. See the attached articles…
Hi Luis,
You can choose resistor values based on the available voltage that you want to down convert to 5V/3.3V. If basic isolation is sufficient, you could use ISO7340C. Based on flow directions of signals, any of ISO7340C, ISO7341C, ISO7342C should…
Hi Asaka-san,
For lower power consumption, I suggest that you promote ISO7640FM or ISO7840. Both of these devices have low power and they can go > 90 Mbps. For 25 Mbps, our lowest power device is ISO7340C.
All these devices have lower power than…
