Hi,
I have a circuit that I need to use XOR gate IC using battery power. The chip in question is 74HC86.
As per data sheet the supply current should be between 20 to 40 micro amp, but , if i just power up the chip using vcc and ground, it is using 3 to 7ma of power. tested different chip but same result , the supply voltage is 3.3v, at 5v, it is taking 23ma. am not sure what mistake am doing. the circuit ultimately would use only one gate, although it has 4.

Thank you
