Talk:Small outline integrated circuit

message: It would be nice if there was a single table with dimensions. Something like this:

Many of these came from LSI's pagehttp://www.lapis-semi.com/en/package/sizesop.html. I don't know how manufacturer specific they are. Since dimensions, including pitch, can change based on pin count, it could have all variants, or one which is representative of the class.Ryanneve (talk) 16:33, 13 March 2015 (UTC)

message: i'm 99% sure the 28 pin soic that microchip supply pics in is actually wider than the 28 pin skinny dip they supply the same chips in. Is this standard or a peculiarity of pics? Plugwash 09:41, 2 April 2006 (UTC)
replies: text: Sadly, I am familiar with this. It seems SOIC for most manufacturers only defines pin thickness and pitch. So on one of my boards, our footprint was too wide on one SOIC, and too narrow on another. Luckily it was a low speed signal, so our QA folks were kind enough to rig it to work since it was only a prototype... — RevRagnarok Talk Contrib 20:16, 4 December 2006 (UTC)

message: Is there any way to post package footprints for EDA software here? It would be great to have all Wikipedia pages on chip packages have footprints for Orcad/Protel/Eagle etc.

:I don't think that would really meet the objectives of WP; it's not supposed to be a symbol library repository. :) And I know I have been stuck drawing enough OrCAD symbols to tell you that they're just too individualized. — RevRagnarok Talk Contrib 20:18, 4 December 2006 (UTC)

message: Hey, Perhaps this article can include some information about HSOP http://cache.freescale.com/files/analog/doc/app_note/AN2388.pdf packages since its not available anywhere. They are basically soics with a heat sink at the bottom. MC33887 is an example. Shall i include it or? Malithyapa (talk) 07:29, 30 June 2011 (UTC)

message: According to the Texas Instruments package guide, SOP (and SOT) have 1.27mm pitch pins. Only the TSOP and SSOP variants are 0.635mm. This should be verified and written more clearly. The current SOP section is misleading. --Onitake (talk) 12:44, 10 June 2013 (UTC)

message: This page shows examples of MSOP archived MSOP specs.
But note that the example given for MSOP-8 is not accurate in all cases. The datasheet for Microchip MCP453X/455X/463X/465X shows a MSOP-8 package with pitch of 0.65 mm and a bodywidth of 3 mm x 3 mm. So there is some variability there between manufacturers. MSOP may need it's own page, as other form factors appear to have.
