Part Number: PCA9534A Other Parts Discussed in Thread: TCA9534A Tool/software: Hi, I understand this is rather an old but very common part. Is there any EOL plan for this part and if there is, will there be an drop-in replacement? As the recommended…
Part Number: PCA9534A Hi team,
My customer is using our PCA9534A ,and they find when they config 0 x03 ,the value read and wrote is not the same.
They also check the input register 0x00 ,they find the value also can't match the input voltage.
Could you…

Hi Team,
We have implemented the below circuitry in one of our board.
In this application, the MCU is STM32H747 which is 1.8V I2C rail…
Part Number: PCA9534A Hey, we tend to use this device on our board.
In a case of write operation, when the master send the command byte wrong with a sixth 6 MSbits other than zeros ("0") how would the slave acts?
For example instead of 0x03…
Part Number: PCA9534A Hello,
In the data sheet, page number:16 it was mentioned that "Resetting the interrupt circuit is achieved when data on the port is changed to the original setting, data is read from the port that generated the interrupt."…
Part Number: PCA9534A Dear Sir or Madam,
I am having problems getting communication with the PCA9534A.
I see the CLK and SDA lines are pulling the commands on the i2c bus low in the correct way. the same circuit work when implemented on a different board…
Part Number: PCA9534A Using TI's expansion chip, model: PCA9534ARGTR schematic diagram:
Problem phenomenon: 1. The software cannot read the device through IIC; 2. In the schematic diagram above, before the IIC inlet of R18 R19 (remove the resistance…
Part Number: PCA9534A Other Parts Discussed in Thread: PCA9554A , TCA9534A , TCA9554A , TCA9534 Hello,
I am using 3x PCA9534A IO expanders and sometimes the device will hold the SDA line low at power up. All that is on the bus is a micro controller and 3x…
Part Number: PCA9534A Hi,
For VQFN 3x3mm package there are two drawings (RGT0016A and RGT0016C) in datasheet which have different exposed thermal pad size. I couldn't find any information on which is correct or related to part number. I would probably…
