Hello guys, I am new to electronics. While I was experimenting with 74LS series ICs, I saw the peculiarity, that the I/O current does not match the specifications for the IC. For example the 74LS00 IC specification says, that its Output High current is -400 micrcoA, But I am getting close to 170 miliA. What the **** is happening!! How to measure these Output current properly..

If you do not understand the question pls ask.
