Hi,

Hey Jim,
Can you provide details on the eSPI bus?
Hi Hubbard,
What's condition and detail information you need, I'll ask my customer and feedback to you, thanks.
Hey Jim,
I need to know the directionality of the signals to confirm in a unidirectional buffer will work. I will also need information on voltages and speeds.
Hi Hubbard,
Please see below eSPI spec, If SN74LVC244A is not suitable for eSPI, could you suggest solution?
Hey Jim,
No, a unidirectional buffer is not going to be able to support bidirectional signals, unless you know something about how they are planning to use it that I don't. TXB0106 would be a good device, but it will likely only support the lower clock speeds.
Hi Hubbard,
Customer SPI speed is 30 MHz, could TXB0106PWR support it?
Also, I just figure out one things, even eSPI is I/O buses, but customer use it at end device: 7 seg LED, so, it will only be output.
Could you please confirm in this situation, whether customer can use SN74LVC244A?
The TXB output drivers are too weak to support the eSPI pull-up/pull-down resistors.
If you can guarantee that the signals to the 7-segment LED are unidirectional at the electrical level (which is not the same as at the protocol level), then a unidirection buffer like the SN74LVC244A will work. What particular LED controller is being used?
