Part Number: TCA6408A Other Parts Discussed in Thread: TCAL6408 ,
Hi TI team:
The IO Expander IC in our current product uses your company's TCA6408A chip. We are currently evaluating whether we can replace it with your TCAL6408 chip;
We found that…
Part Number: TCAL6408 As we know the I2C rise/falling timing requirement as below. We tried to chnage our serial resistors over 100Ohm from 0Ohm but the rise/falling time didn't have change. Would like to confirm the rising/falling time to quick (15.7ns…
Part Number: TCAL6408 Hi
We are using TCAL6408DTUR in our design. i would like to know the RESET and INT signal connection requirements. Do we need to control both signals via MCU?

Is there an I/O expander IC like the TCAL6408 where the I/O pins are open-drain (the internal MOSFET only…
Part Number: TCAL6408 Tool/software: Hello TI,
When the ADDR pin sample to define the Device address? is it at power up or out of Reset or some other state?
Please advise
Thanks

Hi TI Team
I’m using a TCAL6408 for a keypad, but the INT pin never toggles (INT side 10K pull up is there). The Interrupt Status register does change correctly when keys are pressed (I2C reads…
Part Number: TCAL6408 Other Parts Discussed in Thread: TCAL9538 Tool/software: Hello, My customer is looking for a small I2C I/O expander and interested in TCAL9538DTUR and TCAL6408DTUR. At first glance he found the following two differences between them…
