Other Parts Discussed in Thread: TXB0104

Hi,

I've used TXB0104 at my schematic. VCC A is 3.3V suspend power. VCC B is 3.3V core power. Signal is LPC.

Two question need check.

First, If i don't need four channel, Just need three. another pin out just floating or need pull high /down ...??

Second, Is OK for design when VCC A=3.3V and VCC B=3.3V OE pull 10K to VCCA.(Just need isolation function) 

Thanks!!
