Dear Sir :
If /OE connect to GND, then input B port is "high impedance".
What's A port ??
If Oe is Gnd then B is will be connected to A. Not High impedance. If Oe is high the the switch is Open and not connected to A. The A pin will be high impedance when OE is high and the B pin will be at the Bias level.
can you please explain the "Bias level" thing in more detail?
Up to now, I thought that both sides of the switch are high impedance when the switch is off.
I am looking forward to your answer.
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.
thanks for the explanation.
