Is TC4SU69F Toshiba CMOS IC, a good choice for designing an oscillator circuit with 17kHzcrystal input? What are the factors to be considered for designing an oscillator circuit without getting cross talk and jitter noise?

No, because it has been discontinued.
Don‘t waste your effort designing in something you won’t be able to buy later.
I‘ve never seen a 17kHz crystal either.

Hey Thanks,
Where can I find the information regarding ICs discontinued and new models?
My application is unique with low frequency crystals...

Digikey has 25,000 parts. When I look up that party. If I try to find inventory another way I see only 3000. I am not certain.
Quest thinks there is a real of them. I have never worked with them.

Which is the best new CMOS inverter IC to design a crystal oscillator typically low frequency application?

74hcu04 seems to be popular With 32.768kHz crystals, but most applications have the oscillator built into another IC.
At that frequency you could probably use an op-amp.
Are you trying to produce a sinewave or a squarewave?
