Part Number: PCA9555 Hi,
I checked datasheet and found the device I/O port can be programmed as input or output port.
Could you please help to check if I can follow below table to set I/O port?
How to do that and what's the command?
And please help…
Part Number: PCA9555 Other Parts Discussed in Thread: PCA9548A Hi, what's the difference between PCA9555 and PCA9548A?
I can't find the datasheet of PCA9548A from ti.com. Does PCA9548A cover all specs of PCA9555 and replace it?
You can also contact…
Part Number: TCA9555 Other Parts Discussed in Thread: PCA9555 , Hi Team,
Can you provide a rollover guide from a competitor PCA9555 to our TCA9555? Please cover both the hardware and software changes required.
Part Number: PCA9555 Other Parts Discussed in Thread: TCA9555 Hi E2E,
1. Could you kindly let us know PCA9555 output can be inverted by hardware method?
2. Did we just only set reg 0x04 and 0x05 to inverted the output?
Part Number: PCA9555 Hi Sir,
I plan to use PCA9555 as an smbus expander as an output signal to trigger high active, but I didn't have external pull up resistor in I/O pin,
Is it suitable for PCA9555?
Part Number: PCA9555 Other Parts Discussed in Thread: TCA9555 Hi,
I am trying to establish communication with PCA9555 io-expander chip via I2C, I am receiving NAK and my controller stops communication as expected. I even changed the chip with assumption…
Part Number: PCA9555 When input data differ from input register state, PCA9555 will trigger the interrupt signal to I2C master, right?
In case I2C master connected eight devices of PCA9555, all of I/O port connected to individual DUT.
Could the I2C m…
