Part Number: TCA9534
Good afternoon,
There is the requirement to include some TCA9534 devices on our design, and to start developing a simple driver for it, I have one IC soldered on an expansion board.
The problem is that the device does not respond…
Part Number: TCA9534 Hello,
Is there any TCA9534 driver can support in Linux?
And what is the document in web site(SW & tools) "I/O Expander Software and Firmware Package (Rev. A)"?
Thanks
Part Number: TCA9534 Are the I2C address pins A2:0 latched once at powerup, or are they re-sampled each time so you can change the I2C address during operation?
Part Number: TCA9554 Hi Sirs,
Sorry to bother you.
We know 9554 have internal 100k PU on IO, but 9534 didn't.
But we would like to know 9554 could replace 9534? or 9534 could replace 9554?
Any risk?
Thanks!!
Measuring a voltage above zero shows that the output tries to drive high, so the I²C communication should be OK.
The ULN has a typical off-state input current of 65 µA, and requires more to switch on. Apparently, the NXP device outputs a little bit…
Part Number: TCA9534 Hi,
I have looked at TCA9534 specs and have a question about it.
My design intent is to use the port expander with Vcc at 3.3V with two of the P0-P7 ports would be set as outputs tied to 5V logic circuits and the remaining 6 would…

Part Number: TCA9534 Hello Team,
I am using TCA9534DWR GPIO expander, its voltage rail is 3.3V, and I2C is pull up(3.3v) with 10K resistor. Which is power by using Jetson TX2 developer kit. But after some use its SDA pin shows ground potential and also…
