The
Very Small Outline Package,
or VSOP,
is one of several smaller versions of the
SOIC package, having a compressed
body and a tightened pitch for its gull wing leads. Another smaller version of the SOIC
is the SSOP.
Typical VSOP lead counts range from 8 to
40. Typical VSOP body widths range from 3 mm to 10 mm. VSOP body
heights including the leads typically range from 1.2 mm to 1.25 mm. Some VSOP's
have their leads protruding out of the longer sides while some VSOP's
have their leads protruding out of the shorter sides.
