Part Number: CD74HCT4066-Q1 Other Parts Discussed in Thread: CD74HCT4066 , , TMUX1511 The CD74HCT4066 datasheet states the VIH (input voltage required for "high" detection) to be MIN 3.15V for VCC = 4.5V.
But the CD74HCT4066-Q1 datasheet states for…
The SN74HC4066's V IH is not low enough.
The CD74HCT4066 has TTL-compatible control inputs, which accept 3.3 V control signals. There also are the TMUX1511 or TMUX1112.
Part Number: CD74HCT4066-Q1 I would like to isolate two 3.3V domains, circuit_X connected to circuit_y.
When the switch is off it should insulate from backfeeding from circuit_X domain to the circuit_y domain.
I.e. here i would like to use an analog switch…
Part Number: TMUX1072 Other Parts Discussed in Thread: CD74HCT4066 , CD74HC4066 , CD4066B , SN74LVC1G66 , SN74HC4066 , SN74LV4066A Hi,
We are using TMUX1072 in our design for SPI and some digital signals switching.
Since it is an analog multiplexer, Can use…
Hey Adam, You're correct in that there are really only minor differences such as the operating voltage, timing characteristics, and the bandwidth. These may be a concern depending on the application. If you gave me more information on the characteristics…
Victor,
I didn't see that information in the CD74HCT4066 or CD74HCT4066 datasheet.
Another way the crosstalk from the digital control pin is specified as charge injection. TS12A44513 looks like a device above that has low charge injection.
Thank…
Adam,
thanks for recommending the TS5N412 ! I looked at the datasheet and it looks like it will work well for me. I will order it and try it out.
As for digital, I was referring to a digital-only mux/demux.
I was also looking into the CD74HCT4066. The…
Other Parts Discussed in Thread: CD74HCT4066-Q1 Hi everybody I have a question about the datasheet from CD74HCT4066-Q1 product !
What is the differentiate of: CD74HCT4066QPWRQ1 and HCT4066QPWRG4Q1 is equal ?

Other Parts Discussed in Thread: TRF7970A , CD74HCT4066 , CD74HC4067 , TRF7960 Hi,
I've been playing around with the TRF7970A EVM kit and trying to multiplex an array of coils.
According to TI app note SLOA114 (Low Cost HF RFID Multiplexer Examples) is…
