TCA9548A: Datasheet cannot download.

Hi XY,

The datasheet seems to be available to me from ti.com. I'll send you a copy through email for convenience if you're still unable to download it from the web.

Hi Eric, email received. And this link is now available. Thanks!

Hi Eric, I also want consult the difference between TCA9548A and PCA9548A. Seem to me, only power supply range is different.

We intended to use TCA9548A in a 3.3V and 2.5V system, but we found recently its price rised a lot and a lot venders are out of stock. So I would check PCA9548A as replacement. 

I also noticed in datasheet that PCA9548ADGV /PCA9548APW/ PCA9548ARGER is at NRND or LIFEBUY status. Does this mean TCA9548A  is the future trend and PCA9548A  will be EOL gradually?

Thanks again.

XY, 

Yes, we are moving all users to the TCA version of this device. Unfortunately there has been a high demand for this part recently given the supply issues the world is facing right now, this is why the price is high and the vendors are out of stock.

Hi XY,

The device (PCA) also has a RESET/POR errata pointed out in the datasheet. 

Aside from this, there may be some minor differences in the Electrical Characteristics though that shouldn't make much difference.

Thanks,
