Take a peek at the data sheet.

If your wires are already short, then consider adding a signal integrity resistor ohms in series with the clock pin as close to the driver as possible. Propagation Delay Time, Reset to Q. Low Level Output Voltage. Propagation Delay Time, Datasheet 74ls164 to Q. Thus exceeding operating conditions, all bets are off. When I power-on datasheet 74ls164 circuit, all the LEDs are off. High Level Output Voltage. Low Level Output Current. Do you have an oscilloscope? All inputs are diode- clamped to minimize transmission-line effects.

The length of your clock wire might be a factor in this. A high level input enables the other input which will then determine the state of the first flip-flop. Post as a guest Name. Datasheet 74ls164 are probably getting multiple pulses instead of just one. You should datasheet 74ls164 with the FETs in place.
