how much of dc voltage we can we give at input pins?
can output pin drive a relay?
It's depend on your supply voltage. Input voltage cannot be higher then your supply voltage.
Vdd = supply voltage 3V...15V
No, you need to use additional transistor
The CD4082 is specified to work from approx 3V thru 15V, so the input voltage High will be the same as the voltage used to power the CD4082.
eg: 5V supply means a +5Vmax for a logic high input
10Vsupply +10Vmax input.
The CD4082 can only sink and source about 4mA/2mA respectively, so it not suitable for driving a relay coil directly.
What are you trying to do.?
Here's the specs on that chip.
Edit: I must be really slow today!
