Part Number: TMUX6208
Other Parts Discussed in Thread: CD74AC161, SN74HC161

Hi,

Can you recommend a reference design 4-bit counter that can drive TMUX6208? If none what 4 bit counter is best for TMUX6208?

Thank you.

Hi Maynard,

We have no 4-bit counters that can interface with 1.8V logic. You could cascade four positive edge triggered flip flops to be a down counters shown below:

I recommend using the SN74LVC74A or SN74AUC74.

Sebastian

What is the logic voltage? Counters like the CD74AC161/3 run at 1.8 V, and at higher voltages, there are many counters like the SN74HC161/3.

Hi Sebastian and Clemens,

The counter doesnt have to be 1.8V, it can actually go up to 5V and is meant to convert a single pulse into binary data. Is there PSPICE example to demonstrate 4-bit counter?

Thank you.

May

Hi Maynard,

Thanks for clarifying. In that case, I recommend the following counters: SN74LV161A, and SN74LV163A.

Sebastian
