Hi expert,

Customer is looking for JTAG mux for below application. Is SCANSTA112 good for it? How about using 1:2 TMUX1574 *2?

If both can work, could you please advise what are the pros and cons between the two and showing the comparison?

Regards,

Allan

I want to provide a forewarning here that the support for JTAG devices is limited, as the original National Semiconductor group who supported this product no longer exists, thus limiting our in-depth knowledge about this device.

SCANSTA112 would be the part to support this application.

Please refer to the hardware design guide and app note: http://www.ti.com/lit/an/snla055h/snla055h.pdf.
