Usualy term "16*2 LCD" means alphanumeric display module with driver. Therefore you do not need any "external driver". Usualy these displays are equiped with HD44780 or equivalent and using simple paralel comunication protocol. Some "16*2" displays can be equiped with I2C expander. I dont know which type of display you have (you should be much more specific next time). But i suppose you have one with parallel interface ... then look there:
