Hi Xiwen,
IO levels follow VCC according to your explanation.
If you need separate logic levels for the I2C and GPIO level side, then consider the TCA6416A or TCAL6416.
Given you are looking at an automotive part, we do not have TCAL6416 or TCA6416A in…
Part Number: TCA6408A-Q1 Dear team,
In my understanding, when the device is powered on for the first time, POR is not necessary, right? If so, could you please tell me what application needs POR after the first power on?
If not, could you please tell me…
Part Number: TCA6408A-Q1 What is the current consumption in operating mode for each of the Icci and Iccp of TCA 6408 A-Q1? The Electrical Characteristics in the data sheet specifies the total current value for the Icci + Iccp, but does not describe individual…
Part Number: TCA6408A-Q1 Hi, TI Support Team
My client is measuring timing for the TCA6408A-Q1.
I have a question about I2C Interface Timing described in the datasheet.
There is a Min. value for Ticf in Fast Mode.
Of course, Min. values exist for other…
Part Number: TCA6408A-Q1 Hi Team,
As per TCA6408A-Q1 datasheet Page 29 under “Power Supply Recommendations”, do design need to follow power up pattern/ reset pattern to bring the IO expander out of reset as shown in Fig 36,37. What issues it…

Part Number: TCA6408A-Q1 Other Parts Discussed in Thread: TCA6408
Hi,
Currently we are using TCA 6408 IO Expander to control LED . This IO Expander is connected in the serializer side.we will be using only 4 output(P0-P3) in the IO expander for channel…
Part Number: TCA6408A-Q1 Other Parts Discussed in Thread: TCA6408A Dear Team,
My customer is working on TCA6408AQPWRQ1 to use this device on their design, but they realized that the outputs are pulled high in power up and stay at this state until the SW…
Part Number: TCA6408A-Q1 Other Parts Discussed in Thread: TCA6408A Dear TI,
ZF TRW Automotive is looking for I2C - GPIO expander to support ADAS Camera applications, in that way I found TCA6408A-Q1 as an option but we have some size constraint with package…
Hi Gil,
Gil Hershman71 said: 1. We put chip-scope inside the FPGA (which has the I2C controller IP).
The data it shows is what the software reads.
It is not like putting scope probes but it is very close to that.
Understood on this. I was trying to see…
