Confirm whether we can use AD574ASD/883B in the design

Question

@ 
 Hi, 
 We have selected part AD574ASD/883B (ADC Single SAR 12-bit Parallel 28-Pin SBCDIP). 
 In Analog Devices website it is showing that all the parts of family AD574ASD are NRND (Not Recommended For New Design). 
 Please confirm whether I can go ahead with the part AD574ASD/883B, Is there any difficulty in procurement and getting future technical supports during functionality testing If I choose this part. 
 Regards,

Do you need a military part(883BB) or just military temperature? 
 Do you need a ceramic package? 
 I'm assuming with an FPGA, you can accept parallel or serial interface?

People want faster, more bits, and smaller packages, so more and more ADCs are serial. However, 
 you could look at the AD676, AD1674, or AD7880. If you want an AD574, you will have to buy 
 the 5962xxxx full mil part.

 As a side note, NRFD does NOT mean the part is going obsolete; it simply means that it is a mature product, 
 and there are newer parts that you should consider. For example, more bits, faster, lower cost because they 
 are on a newer process, etc. But if the rest of the world is designing in the newer parts, and the existing 
 customers drop off one by one, eventually it will be announced for obsolescence, it which case we give you 
 one year for your final buy.
