Other Parts Discussed in Thread: TMUX1209
Hi,
I have a PCB designed for TMUX1209PWR, but it is currently "out of stock" at pretty much any distributor I could find. According to the website TMUX1109 is a "drop-in replacement" for the chip. What bothers me, is that pin 3 is "nc" on TMUX1209, but Vss on TMUX1109, and using TMUX1109 with my PCB will leave the Vss pin floating. Thus, is there anything internally in TMUX1109 that allows it to be used with a floating Vss pin?
Thanks in advance for the help,
- d
