Part Number: AM6422 Other Parts Discussed in Thread: PCA9534 Hi experts
I have a question about GPIO initialization.
My customer used an I2C-to-GPIO chip (PCA9534) to control the reset signal of the PHY, and then the PCA9534 shares I2C3 with an EEPROM…

Hello,
Following TI wiki guides as well as some guidance on this forum in another thread , I have been able to setup a GPIO line to wake the system from deep sleep. However, I have found…
Part Number: PCA9534 Hi:
I am debugging PCA9534. However I am having the I2C communication problem with this part. Here is the schematic I designed for my application for your reference.
I tried to communicate with the PCA9534, but I did not get ACK from…
Part Number: TCA9536 Other Parts Discussed in Thread: TCA9534 , PCA9534 HI ,
I will use the Arduino UNO R3 EVB to control the TCA9536,
Please share any source code for I2C control for reference.

Hi There:
I'd like to check an application schemtic as following, if using PCA9534 to replace PCF8574 (NXP's P/N).
What items need to be take care or which issue…
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…
