Hi,
I am using TCA9555 three chips connected to same I2C bus and another I2C Temperature sensing chip TMP275AID. So basically, I have total four I2C…
Part Number: TCA9555 Hello,
We are using TCA9555 to drive Led's (MPN: WP130WCP/2EGW).
And we are getting output voltage 1.6VDC from Port 14 to port 17 instead of 3.2 VDC as per logic.
Please share your valuable feedbacks or suggestions.
Thanks…
Part Number: TCA9555 Other Parts Discussed in Thread: TCA9534 I'm using four TCA9555 devices over a single I2C bus at 400KHz. In particulary noisy conditions, the bus is busy and I recover it sendind to the slave TCA9555 a train of 9 clock pulses.
Is…
Part Number: TM4C1294NCPDT Other Parts Discussed in Thread: TCA9555 I am trying to interface an LED display board based on TCA9555 through i2c. Used I2C0 in TM4c1294NCPDT. Configured Port0 as output in TCA9555. However the LED is not on. The code snippet…
Part Number: TCA9555 Other Parts Discussed in Thread: TM4C1292NCPDT ,
Hi,
I need to know how much input supply current I can give to the IO expander IC for one channel with respect to VCC 3.3V.
In my circuit, I'm connecting I2C lines of TM4C1292NCPDT…
Hey Andrei,
I was just following up on this thread, were you able to address your initial issue from this thread? Or were there any other questions you had?
Regards,
Hello Andrei,
Yes, it is OK control the address pins of TCA9555 via MCU GPIOs so that their value can be changed dynamically during operation. (The address value is not "latched" by the device, e.g., at start-up.) You can read more about this idea in…
Part Number: TCA9555 Asking on behalf of customer.
The TCA9555RTWR is out of stock; can the TCA9555RGER be used as a drop in replacement without modifying the PCB?
It appears the PCB patterns are very very similar.
Thanks!
