CD4072B: Sinking current at 3.3V

Part Number: CD4072B

Our design choose CD4072B working at 3.3V supply. So I need to know about the sinking current at 3.3V, since the device's datasheet doesn't appeared parameter for 3.3V. Thank you in advance.

    CD4000 devices are designed for higher voltages. At 3.3 V, there are no guaranteed electrical characteristics. The sinking current is likely to be much worse than that at 5 V, probably no more than 20 µA.

    You should use OR gates from a family like LVC. If you need four inputs, combine multiple OR gates.
