PCA9548A: PCA9548A – To replace PCA9547 (NXP)

Hi Gary,

The NXP and TI device are meant to be replaceable, they will perform the same function. They are also P2P compatible.

However we recommend upgrading TI's PCA9548A  to TI's TCA9548A. All TCA devices are P2P replacements of their PCA counterparts. They have a wider operating voltage and the TCA9548A has corrected the reset errata. They also use newer processes which make them more cost effective.

I looked online but I was not able to find a comparison table, I'll reach out to my team and let you know if we find one.

Best,

Chris

Hi Gary,

So it doesn't look like we made a comparison table for this. Some quick differences between the PCA9547(NXP) and PCA9548A(TI)

The device address are the same: 1110A2A1A0

NXP device is a MUX, TI device is a switch

The lower limit for VCC is higher for the NXP device.

Best,

Chris
