Part Number: TCA6424A Tool/software: Does this device (TCA6424A) support clock stretching in accordance with the I2C specification? (The datasheet does not seem to mention clock stretching for SCL, so please let me check.)
Part Number: TCA6424A Tool/software: About TCA6424A
I have a question about the timing requirements of the I2C interface.
I would like to confirm the definition of tsp (I2C spike time). Does it apply when the voltage level drops due to noise, causing…
Part Number: TCA6424A Other Parts Discussed in Thread: TCAL6416 , TCAL9539 , TCA8418E Tool/software: The questions are as follows.
For example, when used as an input port and a switch circuit is connected to the port terminal to turn it on/off, does…
Part Number: TCA6424A Tool/software: Dear support team,
I'm trying to get a TCA6424A to work. Sadly, it doesn't reply at all to I2C commands. Another slave on the same bus works without any problems. I would appreciate if you could point me at the thing…
Part Number: TCA6424A Tool/software: I have a question about the reset timing requirements for the TCA6424A.
The relevant parts of the datasheet are "6.7 Reset Timing Requirements" and "Figure 7-4. Reset Load Circuits and Voltage Waveforms".
Could…
Part Number: TCA6424A Tool/software: ◆Question
If SDA is an output, please tell me the standard values (electrical characteristics) of VOH and VOL.
※ It seems that this is not stated in the TCA6424A data sheet.
Best regards
Part Number: TCA6424A Tool/software: ◆Question
Is it okay to use this circuit for unused ports? (Does it need to be connected to VCCI or GND?)
In Table 5-1. Pin Functions, it is set as an input at power up.
Best regards
Part Number: TCA6424A Other Parts Discussed in Thread: TCA9555 Is it possible tyo change the address of the device by driving the ADDR pin high/low without reseting the device.
The idea is that we need to have over 100 IO (5+ devices). My idea is using…
Part Number: TCA6424A Hi TI Team,
In my design we are using TCA6424A I/O Expander 24 I2C connected to MCU(STM32F779B), we are not able to read proper input value from external pull up individual port pins, please suggest reference code for reading correct…
Part Number: TCA6424A Tool/software: Hi TI team,
During system boot-up, when configuring certain GPIO pins as output, we observe that the GPIO pins automatically transition to a high logic level immediately after setting the direction to output. Could…
