Part Number: SN74CBT3251 Vcc will be 5V however the Select and OE pins will be driven by MCU at 3.3V. On the SN74CBT3251, are the Select & OE pins isolated from Vcc? Or do we need to ensure that the MCU has 5V tolerant pins?
Thank you
Zhilai,
The SN74CBTXXXX family of switches are single NMOS FET switches. In order for the FET to have a low impedance path from drain to source (A to B) the Vgs voltage must be greater than the FETs threshold voltage. With this type of switch you will…
Part Number: SN74CBT3251 Hi,
I'd like to test several resistive sensors versus temperature. Outside of the climatic chamber I'll have a board (Arduino driven) that will switch the precision ampermeter to each sensor.
The only issue I see is the…
Part Number: SN74CBT3251 Hi team,
My customer is looking for 8 channel analog switch solution that could support 1.8V Vcc, just like SN74CBT3251, but the min Vcc of SN74CBT3251 is 4V.
Do we have any solution to it?
Thank you.

Want to know output state at power up for ACT logic. For example if ACT04 input A is tied to GND (low), what will be situation on output…
Part Number: CD74HCT4067 Other Parts Discussed in Thread: TMUX1208 , ULN2803A , TMUX1308 , SN74CBT3251 Hi,
Just to confirm, to increase the output current of the I/O can the cd74hct4067 be cascaded like parallel memory one on-top of the other?
Thank you…

Hello, I'm trying to search for a 1:8 demux from TI.
I use MSP430G2 launchpad to generate PWM signals (10 ~ 10kHz, 1~60% duty cycle) and this is connected to…
Hi Eric,
Thanks for your interest in our 8:1 muxes.
TMUX1208 is a great choice because it has a wider supply voltage range, break-before-make switching, fail-safe logic, and supports 1.8V control inputs.
I would also like to suggest taking a look at our…
Hi Pavlin,
If you are worried about unwanted movement, it is better to use logic to pass the STEP pulse to the drive you want.
You can use AND logic or an IC like the SN74CBT3251 connected like Figure 4.
