It depends upon some important information that you did not supply...
Determine from schematic the intended 'HC595 supply voltage... FET Part number... Pointer to the FET data sheet... Get from data sheet important spec of FET gate threshold voltage curves... Get from data sheet important spec of FET gate capacitance... Pointer to the 74HC595 data sheet... Get from data sheet important spec of 'HC595 VOH and VOL voltages... Get from data sheet important spec of 'HC595 output high and low drive current capability... Get from data sheet important spec of 'HC595 VDD operating voltage range... Muhammad, so you see the important takeaway here is that the key to answering your question lies in studying the data sheets for your parts. Michael Karas |
