Part Number: TCA6416A Other Parts Discussed in Thread: SN74HCS595 , SN74HCS165 , MSP430FR2000 Dear team,
I am looking for I/O expander for SPI interface. Did we have solution now?
I have found some related post about SPI application. May i learn from you…
Part Number: TCA6416A Other Parts Discussed in Thread: TCA6416 Hello,
I need a little help determine exactly what's changed between the TCA6416 and the TCA6416A. I understand that there have been improvements regarding the interrupts and the reset…
Part Number: TCA6416A Hello,
Our application requires a PWM output from TCA6416A.
We are using 10 ports as outputs and 3 ports as inputs from TCA6416A in total. Using Port P13 to generate PWM with a frequency of 1.5kHz.
Our duty cycle requirement for…
Part Number: TCA6416A Hi,
Good Day. QFN package pin 18 ADDR, when not connect high, does this pin need to be ground? Please advise. Thank you very much.
Best Regards,

Part Number: TCA6416A Hi, all
there is not listed the order number of BGA version of TCA6416A. would you like kindly help check if the BGA TCA6416A is already released?
Part Number: TCA6416A Hello,
We are working with this device on a new design, interfacing with an STM32 microcontroller.
We've found that communication with the device is inconsistent, and it appears to enter a fault mode where it holds the SDA line low…
Part Number: TCA6416A Hi Team ,
Please review the attached schematic of I2C based GPIO Expander :
Pull-up of value 10k has been added on all signals which are to be used as input ports .
Thanks,
Manoj
Part Number: TCA6416A Hello,
I have issue with P00 - P17 outputs.
1.
The P00 used as output with 2.2KOhm Pull Up resistor.
Connected to 3.3v power supply
The other circuit on this output disconnected for this test.
In this setup the output can't down…
Part Number: TCA6416A Other Parts Discussed in Thread: TCA6408A , , TCA9548A Hello,
I am having the same problem as "user4646208": No ACK (SDA is high on ACK clock pulse) from a TCA6416A as well as a TCA6408A device.
Both devices are connected…
