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 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…
Part Number: PCA9534A Hi team,
I have customer design PCA9534A and need some support for design.
He needs some data or document that about reference design and application note to planning GPIO extender function.
Can you help in this?
Part Number: PCA9534A
Good day Colleagues,
My customer is using I/O expander TCA9534APWR, but he found a possible replacement of PCA9534APWR which are in stock now.
The only parameter that is under questing is minimum supply voltage of 2.3V . His our…
Part Number: PCA9534A Other Parts Discussed in Thread: PCA9543A Hi,
I designed the PCA9543A to connects one Master device and two Slave devices.
If the master device makes the i2c signal low, Where does the sink current from the pull-up resistor tied to…
Part Number: PCA9534A _
We have a circuit board with a Linux System on Module. One of the SOM's I2C ports is connected to two PCA9534A I/O expanders. One of these expanders has its address pins all tied low, so its I2C address is 20H. The other has its…
Part Number: TCA9534A Other Parts Discussed in Thread: PCA9534A , Hi Team, aside from the supply voltage we want to further understand the difference between PCA9534A and TCA9534A.
Thank you.
Part Number: PCA9534A Other Parts Discussed in Thread: PCF8574
We have grounded the A0,A1,A2 pins of this chip, and hence I expected to find the device at address 0x38, but when I run an i2c scanner it doesn’t find anything at 0x38. It does find…
