SSOP (Shrink Small Outline) & QSOP (Quarter-Size Small Outline) are leadframe based, plastic encapsulated packages that are well suited for applications requiring optimum performance in IC packaging with applications requiring compressed body size and tightened lead pitch. These industry standard IC packages yield a significant reduction in size while running in high volume and provide value added low cost solutions for a wide range of applications. A green BOM is standard, allowing devices to meet applicable Pb free and RoHS standards.
