Part Number: TCA8418 Tool/software: Dear Sir/Mam
Give the Grade details (automotive/industrial/commercial), End of Life, FIT rate with respect to CL=95% , temp=55 deg C.
Part Number: TCA8418 Tool/software: Hello,
We have some carbon touch detection problems on a product.
I think it's more caused by the Keyboard definition than the TCA8418.
I try to understand how TCA8418 works.
Datasheet shows that a pull-up of 105K…
Part Number: TCA8418E Tool/software: Hi all,
My question is any drawback or problem if i use the 1KR added between TCA8418E ( Key Scan IC ) and the Key.
Those 1KR was used the prevent the ESD.
Any drawback of it ? We just add 1KR column & the Key ( attached…
Part Number: TCA8418 Tool/software: Hi team,
I understand that the pull-up resistor can be disabled by a register. However, when used in key-badged mode, there is a statement in the datasheet "8.4.2.1" that the columns are disabled but the rows are not…
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 or…
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…
Part Number: TCA8418 Hi team,
I am trying to implement this device with the attached circuit using an external pull-up. The internal pull-up will be turned off with a register. Is there any problem?
Also, am I correct in thinking that in keyscan mode…
Part Number: TCA8418 Other Parts Discussed in Thread: STRIKE ,
Regarding the ESD protection of this chip, according to the specifications, there is built-in ESD protection. However, even if we apply static air of 10KV, it will still cause damage to TCA8418…
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…
