Part Number: TCA9509
I understand that TCA9509 has SDA and SCL bus for I2C bus, but now my customer consider to use it other purpose and they need only one channel. Then can they leave open the unused bus or need to tie VCCx or GND?
Satoshi / Japan Disty
What other purpose are they going to try? I don't understand how they hope to communicate with the device by removing on either the SCLK or SDATA? You need both signals to communicate. Please give a more detailed explanation of what they are trying to do.
