Part Number: TCA6418E
Hello,
Q1:
The following E2E thread says R θJA = 64.4oC/W, but datasheet says it is 98.8oC/W. Which is true?
Q2:
What is the maximum tj for recommended operating conditions and absolute maximum rating respectively…

Part Number: TCA6418E Dear Team,
Good day!!
TCA6418EYFPR has 18 GPIO's, can i tie the unused GPIOs permanently to GND without any external pulldown resistor.
Part Number: TCA6418E Other Parts Discussed in Thread: TCA8418E , TCA8418 Hi TI Support Team,
I have questions about register description of TCA6418E.
In register map, there is mention such as "read twice to clear" at GPIO_DAT_STATx registers.…
Part Number: TCA6418E Hello TI support team,
I find the register bit mapping of GPIO0-7 is inverse to its register bit alignment. Is this correct?
Below is from P.12 of datasheet http://www.ti.com/jp/lit/ds/symlink/tca6418e.pdf .

Part Number: TCA6418E Hi Sir,
Form TCA6418E datasheet mention that the INT pin connect to VCC through a pull up resistor.
For this open-drain structure, could we connect to 3V3 through a pull up resistor, but the VCC is1.8V?
Please help to advice,
Thank…
Part Number: TCA6418E Other Parts Discussed in Thread: TCA8418E , TCA8418 Hi, My customer surveys for 6 channels (or above) I2C to GPIO expander solution and needs to support 1MHz I2C. Please help to check if more proper solution to recommend except TCA6418E…
Part Number: TCA6418E HI Sir,
I saw following descriptions in your TCA6418E datasheet, in page 14,
GPIO Data Status Registers, GPIO_DAT_STAT1–3 (Address 0×14–0×16) These registers show GPIO state when read for inputs and outputs…
Part Number: TCA6418E Hi Team,
My customer is looking for SPI to GPIO expander, they need at least 8 GPIOs, better 16 GPIOs with 5V supply.
I see we just have I2C expander, but not SPI. So would you pls help recommend if we have, thanks a lot!
Best regards…
Part Number: TCA6418E Hello Team;
Could you specify what is Low Standby current mode for TCA6418E?
The datasheet "FEATURES" specify "• Low Standby (Idle) Current Consumption: 3 μA", but no detail for this mode..
Thanks
Macs…
