SN75ALS174: SN75ALS174 pin assignment

Part Number: SN75ALS174


I would like to know the difference between SN75ALS174 and SN75ALS174A.

According to the below site, 

http://www.ti.com/product/SN75ALS174?keyMatch=SN75ALS174&tisearch=Search-EN-Everything

It shows "The device has the SAME FUNCTIONALITY as the compared device,

but is not pin-for-pin equivalent and may not be parametrically equivalent.

Could you show me the difference?
