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: Hi team,
With the reset pin set to “H”, the output goes High when the power is turned on. I have an LED connected to 13-pin COL4 and it lights up momentarily. It turns off when the register setting by I2C is completed…

Hi, I asked this question long ago and somehow i resolved the problem but I lost the solution due to window problem and i am back to the same problem. I am using the given code that i downloaded from a github. Linked given on the…
Part Number: TCA8418 Tool/software: Hi
We are using TCA8418 as GPIO and interrupt expander.
One of the interrupt is active low input to GPI. It is possible this signal gets asserted (pulled low) before interrupt is enabled.
From logic analyzer,…
Part Number: TCA8418 The TCA8418 key scanner IC, contains a FIFO which stores both "Pressed" and "Released" events. I want to configure it to save only the "Pressed" events. How can I do it and what are the register addresses and the values that I should…
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…
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…
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…
