Part Number: TCA6418E Hello, Q1: When RESET_ pin is not used, how much ohms resister does TI recommend to pull up the RESER_ pin to Vcc? Q2: When INT_ pin is not used, can this pin be left floating (unconnected anywhere)? Q3: How unused GPIO pins are…
Part Number: TCA6418E Other Parts Discussed in Thread: TCA8418E Hi TI Team,
I'm applying TCA6418E on a 6 layers board of an IOT product.
Could you provide the reference layout design of your EVM board?
The data sheet doesn't have much info of the…

Part Number: TCA6418E Dear Team,
This is my configuration.
GPIO 0 - 5 want to use as keypad inputs which have a pull up connected of 10K on the outside, pin goes low when keypad input is pressed and when released high, GPIO 6 - 7 directly connected…
Hi Maki,
We don't have a TCA6418E EVM. The customer will likely need to use a breakout board as a potential method to evaluate the device.
I found one which may work here (not 100% sure though, the pitch and grid match. Stencil on page 31 matches…
Part Number: TCA6418E Other Parts Discussed in Thread: TCA6416A , TCA9539 I’ve been reading through a copy of the datasheet (SCPS243 –SEPTEMBER 2012) and I haven’t been able to find the answer to the following question. Could you please answer it or point…
Part Number: TCA6418E Hello,
1.) I've just started working with the TCA6418E and am in the middle of bringing up the board. I've inadvertently left the reset pin floating on the TCA6418E on the latest rev of my design. Per the datasheet, I understand…

Customer have a question as below
Do we have the same function as TCA6418E and package need to be bigger?
Customer want this function below (can check GPIO status)
