Package Information PACKAGE TYPE: 14 SOIC Package Code S14-1 Outline Number 21-0041 Land Pattern Number 90-0112 SINGLE-LAYER BOARD Junction to Ambient ( ) 120C/W JA Junction to Case ( ) 37C/W JC FOUR-LAYER BOARD Junction to Ambient ( ) 84C/W JA Junction to Case ( ) 34C/W JC For the latest package outline information and land patterns (footprints), go to www.maximintegrated.com/packages. Note that a +, , or - in the package code indicates RoHS status only. Package drawings may show a different suffix character, but the drawing pertains to the package regardless of RoHS status. Package thermal resistances were obtained using the method described in JEDEC specification JESD51-7, using a four-layer board.
