Part Number: SN74CB3Q16211 We are using the bus switch SN74CB3Q16211DGVR in one of our design. We are seeing undershoot of 0.480mV on one of the pins. This undershoot is seen on the I2C transaction and that too only when slave sends the data. There is…
Part Number: SN74CB3Q16211 Hi,
We have an application where we want a switching mux like device for connecting a master JTAG debugger (debug connector) to multiple slave debug (connectors) .
consider the following application circuit. I am thinking…
Part Number: SN74CB3Q16211 Hi, We are trying to measure the ON-resistance (Ron) of the switch channel.
However the Ron measurement are very different from the spec values (spec values are around 5ohms).
The following are the test conditions:
…
Part Number: SN74CB3Q16211 Hi,
My cusotmer wants to know if SN74CB3Q16211 can suport hotswap applicaiotn?
I can't find such discription on datsheet, can you help to check and give some comments?
Thanks a lot.

Part Number: SN74CBT16210C Other Parts Discussed in Thread: TPS22919 , SN74CBTLV3861 , TMUX1511 , SN74CB3Q16211 The datasheet did not have the ON resistance value or chart to show when Vin=3.3 and Vin=5V @VCC=5V. Can someone tell me the resistance number…
If you want the bus to the UUT to be high impedance when off, then using the A port for that is correct.
The B port, which can be precharged, is supposed to be connected to the bus where hot-plugging happens. But in your case, there are no other receivers…
Other Parts Discussed in Thread: SN74CB3T16211 , SN74CB3Q16211 Hi,
We have used a SN74CB3T16211 in our design.
We basically want to shift 5V input to 3.3V output.
But due to the unavailability of the above chip (BGA version),
we are thinking…
take a look at level 3 in the attached. The Bias pin precharges the I/Os ath powerup by connecting the Bias pin before Vcc.
If you do not need this feature then use the SN74CB3Q16211 instead. Same part without Bias pin.
This part is a switch or a simple connection so there will be no dir pin. The output high will be clamped to Vcc but anything lower will pass through.I beleve this part will work in your application with the exception of being powered by 5V
1) Can…
