Could someone please tell me the difference between the SMD packages SOIC & TSSOP please. They look the same to me.
 
SOIC(also known as SOP) has 50mil pin pitch(0.05" = 1.27mm), and TSSOP is typically smaller and metric, as well as thinner. Check the data sheets for the real numbers, but pin pitch varies from .65mm - .4mm

Thanks for that. Sorry, I should have checked the last page of the data sheet.
