The PDF file you attached is for MC10EL32/MC100EL32. If this is the chip you are actually using then don't expect it to work. This is an emitter-coupled logic (ECL) gate and is not compatible with TTL or CMOS voltages.

You may want to use a TTL D-flip-flop such as 74LS74 or a CMOS type such as the MC14013B, or 74HC74 etc.

Its mainly high. I have a variable power supply. I have tried keeping the square wave at 5v and move the VCC from 5V to 12v. It doesn't change much either. I have a couple of the flip-flops too, so I don't think its a bad component. In a couple hours I will be able to try tying all the un-used inputs to ground. thanks
