Part Number: TCA6408A Dear Team,
As discussed earlier in the E2E forum, we have used the TCA6408ARGTR as a GPIO expander, as shown in the circuit below.
In the above circuit, we are able to control all the GPIO ports ( P0–P7 ) as expected. However…
Part Number: TCA6408A Hi Team,
When customer does ESD test, the signals on pins 5 and 6 changed from high to low, and it became uncontrollable. It only returned to normal after the power was shut down and restarted. And at this moment, other I/O pins…

Hi Team
Could you please help to provide below parameter for TCA6408ARGTR?
1. Max junction temperature
2. Power dissipation
Thank you very much
Part Number: TCA6408A Other Parts Discussed in Thread: TCA6408 Hi,
I would like to consult with you regarding the application of the TCA6408 IO-EXPANDER. Are there any leakage current concerns when using three of them on the board? Below is our usage…
Part Number: TCA6408A Other Parts Discussed in Thread: TCA9539A-Q1 Hi Experts,
your datasheet page 20 descript "INT resetting occurs in the read mode at the acknowledge (ACK) or not acknowledge (NACK) bit after the rising edge of the SCL signal. " …
Part Number: TCA6408A-Q1 Tool/software: Hi Team,
Regarding - TCA6408ARGTR i2c based IO expander
Please confirm one thing, after configuration all GPIO by MCU, GPIO status will remain same after supply on/off??.
Thanks,

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: TCA6408A Tool/software: Hi Team,
If I have to use 3 of these IO expanders, can interrupts be shorted together and give as single input to CPU?
Thanks,

Part Number: TCA6408A Hello,
The datasheet mentions in multiple locations in order to the set ADDR bit high, the ADDR pin must be connected directly to Vccp. However, the layout drawing example (Figure 11-1) shows the pin connected to Vcci. Could you…
Part Number: TCA6408A Tool/software: Hello. The datasheet for TCA6408ARSVR does not contain RSV-16 (16-UFQFN) package drawing. Is it possible to fix this error? I can see only CAD models? but it's nit enough.
