Part Number:TXB0104
I have a design where I am using MDIO to talk to a PHY chip on my circuit board. However, the customer also wants the ability to converse with the PHY over MDIO. To do this, we've set up a handshake signal to control when my PCB has control and when they have control of MDIO. I would like to use the TXB0104 to gate their usage of the MDIO lines (MDIO and MDC). When OE is tied low the outputs go to high impedance which would work great. I have a few questions however.
1) Can VCCA be made equal to VCCB with no adverse consequences? (I do not need to translate, I just want to use the chip as a gate).
2) I've used the TXS0104e before. It specifically states that it can be used for open drain or push pull applications. Do I need to do anything special for the TXB0104?
3) Are there any other differences between the TXB0104 and the TXS0104e that I would need to be aware of for this application?
Any help here would be appreciated.
Thank you,
