Other Parts Discussed in Thread: SN74LVC245A, SN74LVCR2245A
I want to use the SN74LVT245B level shifter in order to protect my processor from backpowering on a RGMII interface. The processor, which has its own power supplies, is connected to a Ethernet PHY (which also has its own power supplies) through RGMII interface.
We saw that the SN74LVT245B can handle the RGMII interface speed (up to 250Mbps/line @3V3). Could you confirm ?
Then, we would like to know the output impedance of the SN74LVT245B in order to select the serie termination resistor of the line (R?) ?
