PCA9544A: PCA9544A with 8 channels

Part Number: PCA9544A
Other Parts Discussed in Thread: TCA9548A, TCA9544A

I’m looking for a part like the PCA9544A with 8 channels instead of 4. Do we have anything like that?

Mux should support a chip reset and indivdual channel interrupts

    Hey Saminah,

    Unfortunately not. The only 8 channel switch we offer are the PCA/TCA9548A which do not have the INT channels we need.

    The only alternative solution I can think of is to use 2 TCA9544A's or a TCA9548A with some kind of OR gate or an 8 bit I/O expander.

    Thanks,

    -Bobby
