I am unable to get the IC 74C14 from the market. But I did find IC 74HC14. the circuit that I am building is a transistor combo tester which houses IC 74C14. Will it be possible to use 74HC14 instead of 74C14. the diagram is attached herewith. I searched the datasheets of both of them, the only difference I found is VCC. Has anyone know about this, please pass on the information.

hi,
HC logic is designed for 2v to 6v operation
HCT is 4.5v to 5.5v operation
and C 3v to 15v operation.
It should be OK at 6V supply

74C series is standard CMOS, high voltage (3 - 15 V) logic series. You can use CD40106 as a replacement.

Or use 74HC14 with lower supply voltage, e.g. 4.5 V. Although is has 6V supply voltage range, the value may be exceeded when using new batteries.
 

I needed some 74C14 ordinary Cmos ICs but couldn't find it nor CD40106 copies of it. So I bought some Motorola (ON Semi now) MC14584 ICs which are the same.
