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…
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 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 can create…
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…
