Part Number: ISO1540 Other Parts Discussed in Thread: ISO1640 Tool/software: Hello,
ISO1540 is used for IIC isolation, SDA low level will have a voltage bump of 600mV, and there will also be overshoot voltage. How is overshoot voltage generated, and…
Part Number: ISO1540 Tool/software: Hi team,
Could you please elaborate on the following marking changes due to PCN
on the left side is our stock the marking is stripe COO TW
on the right side is Dot COO MY
Part Number: ISO1540 Other Parts Discussed in Thread: ISO1640 Hello Team, We are using ISO1540DR for one of our applications. The following is the block diagram of the same. The IC INA238AIDGST is used to measure some voltage. The voltage measured is isolated…
Part Number: ISO1540 Hi
Found the VOL1 of ISO1540 is ~0.88V, but the I2C's VIL spec of device is 0.8V, seem like it is out of the device's spec. wondering if there are any ideas how to fix it? Thank you.

Hi Allen,
Allen Du said: the A side of TCA9509 VIL Max is 0.3V, but the FPGA on my board VoL max is 0.45V, there will be a problem.
The A side of TCA9509 is actually lower at 150mV typical. Most people don't have an issue with this if they design the bus…
Part Number: ISO1640 Other Parts Discussed in Thread: ISO1540 , Does ISO1640 has lower Vol for Side 1 compared to ISO1540 which has Vol range of 570mV to 800mV?
I am looking for i2c isolator which has lower Vol. We are hitting Vil violation due to high…
Part Number: ISO1540 Hi Ti experts,
We are using ISO I2C ISO1540 to connect MCU and many devices as below:
We found that when ISO1540 receives signals from MCU, there will be a platform at the rise edge as below, which will cause the communication r…
Part Number: ISO1540 Other Parts Discussed in Thread: BQ76942 Hi Team,
Currently, customer used our ISO1540 meet some corner issue:
In customer system, he add a switvh(MOS) in the line of VCC, to turn-on and turn-off ISO1540, but at the time, SDA/SCL…
