Received the following request from Cisco engineer:
"We're looking for I2C GPIO expanders, something like the PCA9539 or PCA9538, but needs to be on a different address than 0xE Is there an alternative standard expander that uses a different address range?"
"Found this one that may work for us. PCA9557 and PCA9575. Looks like you have PCA9557, but not PCA9575. Is there any plan to make a footprint compatible PCA9575 in TSSOP28 package?"
After looking on the TI web page, it doesn't appear that the PCA9575 is a TI part. can you provide a device that meets his requirement in at TSSOP28 package?
