Other Parts Discussed in Thread: TMUX1308, , SN74LVC125A, SN74LVC3G17, SN74ABT541B-Q1
I'd like to design 8 channels demultiplexer for JTAG (Jtag repeater).
Front-end use 4*TMUX1308 as demultiplexer.
(TDI, TDO, TCK, TMS)
TCK work on 75 MHz.
I need to pick up buffer for 2 meter jtag cables.
SN74HCS244-Q1 seems fine,
but I'm not sure it can support 2m cables,
or could I have better solutions?
