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…
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 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-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,
Jitendra
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.
Part Number: TCA6408A Hi Support team
We use the TI I2C EXP TCA6408ARSVR and implement the SI measurement. We checked the spec and found the criteria of fall time as below; It shows the I2C spec is 20+0.1Cb~300ns. As I know the latest I2C spec is (20…
Part Number: TCA6408A Hi Experts,
I would like to confirm the correct connection for ADDR pin.
The datasheet states in table 5-1 Pin Functions (page 3) that ADDR should be connected to VccP or ground. This information is repeated elsewhere in the…
Part Number: TCA6408A Tool/software: after reset, I read registers 0x1 and 0x3 and the values are 0x1 and 0x0. those are different from the TCA6408A datasheet. and even I set P4 high (measure by the pad, it actually high), the value of register 0x3…
