Part Number: TCA8418 Hello team,
Now we switch the TCA8418E to TCA8418, but from 8418E we see the 15kV EDS spcific in datasheet, and no clarify in 8418.
So, could we can use 8418E?
Thanks!
Part Number: TCA8418 I used TCA8418 in my custom product and connected 75 keys as matrix.
I used IC in polling mode. Read every 1msec to detect key.
At power on, all key detection is proper.
But after fast pressing or random pressing, at some moment…
Part Number: TCA8418 Dear Technical Team
I am working on an existing design for an upgrade and found the current design uses TM1637 (Keyboard Scan Interface Chip) which seems non-reliable in terms of manufacture and supply chain. I would like to know…
Part Number: TCA8418 Hi, I read a TI thread and found some Arduino code to interface TCA8418. I am trying to interface with Arduino Leonardo with TCA8418. I have a keypad of 3X9 ROW x COL. Can someone help me to make it work? I need to read the keypress…
Part Number: TCA8418 Tool/software: I am using Adafruit_TCA8418 library .
My configuration is as follows:
Adafruit_TCA8418 keypad;
void setup()

keypad.matrix(5, 10);
keypad.flush();
}
And my code which prints to the serial any key press…
Part Number: TCA8418 Hello,
I'm trying to utilize the keypad lock feature of the TCA8418 to ignore all button presses but unable to get the device to actually enter locked mode. I have followed the application example in the data sheet (9.2.2.2) down…
Part Number: TCA8418 Hi, just wanted to clarify about whether pullups are required or not. In one place, the datasheet says to put pullups on unused inputs, whereas in another place it says that pullups are not required:
"Note that no external pullup…
Part Number: TCA8418 The data sheet for TCA8418RTWR shows the "thermal pad" under the part but there is no mention if this pad must be a no-connect, or if it can be grounded. The examples do not show the connection at all.
The WQFN24 footprint from…
Part Number: TCA8418 Hi team,
My customer designs this device, but They have one question.
They would like to know our devices' behave after POR condition without I2C access?
What status of ROWx and COLx pins?
Are they scanning automatically…
