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?
