Part Number: CD74HC4052 Hi,
I've been using CD74HC4052 (4Channel, Dual MUX) for switching between some analog signals. I was wondering if I could use the same MUX to extend my UART or I2C lines of my microcontroller? The idea is to simply use the S0 and…

Hi Experts,
Currently, i am working with CC1352R to Monitoring&control multiple UART/TTL-based devices so i need your technical support to do this,…
Part Number: CD74HC4052 Other Parts Discussed in Thread: SN74LV4052A , , TMUX1309 the device CD74HC4052 spec says it work on minimum 2V but on the WEB it say it work on 1.8V too.
which is correct?
is there similar functionality device for 1.8V? to mux and…

Part Number: CD74HC4052 Other Parts Discussed in Thread: TMUX1309 , The EE characteristic only shows VIH/VIL for VCC= 2V, 4.5V and 6V. How about VIH(min) and VIL(max) @ VCC= 3.3V?
Part Number: CD74HC4052 Hi team,
Would there any possibility of shorting ON channels when changing input status?
For example, when switching from (S1,S0)=(L,L) to (L,H), is there any chance that A0 and A1 shorted?
Or, is there any integrated protection…
Part Number: CD74HC4052 Hi team,
Could you share the S1 and S0 pin’s voltage when it is open, and the device is powered?
Is it floating? Or, is there any internal pulldown resistors for example?
Best regards,
Kurumi
First of all, thank you for your reply. I understood the solution you suggested. Is VNEG correct to refer to the pin of PCM5102? (PCM5102 [VNEG] -(Connect)- CD74HC4052[VEE]
Hello Jerry,
It seems you are looking for a 4:1 multiplexer capable of passing voltage signals of +/-1V and can handle +/-100uA.
For you application I can recommend the CD74HC4052 . It seems according to the diagram you provided, there are two 4:1 muxes…
Part Number: CD74HC4052 Other Parts Discussed in Thread: TMUX1104 Hello Team,
We have got an opportunity of CD74HC4052 which is targeting big TV screen(100inch) digital SMPS application.
They will use A channel with CD74HC4052.
How could we disable…
