mbeals 74 Posted April 4, 2013 Share Posted April 4, 2013 As I'm browsing through the parts catalog, I keep seeing identical parts with different suffixes and no explanation about what they mean. For example: SN74LVC2G34DBVR SN74LVC2G34DBVRE4 SN74LVC2G34DBVRG4 or ISO7231CDW ISO7231CDWG4 ISO7231CDWR ISO7231CDWRG4 All of them have the exact same specs, including the pin package. The difference is whatever R vs RE4 vs RG4 or G4 vs R vs RG4 means. I've searched the Google...I've searched the data sheets...I've searched TI's site....nothing The only possible difference I see is the occasional difference in how it's packaged...aka Reel Vs cut tape. Does anyone know how to decode this? Quote Link to post Share on other sites
cde 334 Posted April 4, 2013 Share Posted April 4, 2013 http://focus.ti.com/quality/docs/gencontent.tsp?templateId=5909&navigationId=11753&contentId=5055 E4 and g4 refer to lead free packaging and molding options (see link). R is normally for Large Tape & Reel (3000) vs the non-r 250 reel. And they used to have some for temperature rating, but they pretty much phased those out a few years ago. mbeals and GG430 2 Quote Link to post Share on other sites
GG430 53 Posted April 4, 2013 Share Posted April 4, 2013 True, this is kind of a confusing system. cde captured your examples. MSP430 specific there are a couple others. MSP430F2274IDA MSP430F2274IDAT MSP430F2274IDAR MSP430F2274TDA MSP430F2274TDAT MSP430F2274TDAR DA = Package (http://www.ti.com/sc/docs/psheets/mechanic.htm) I/T = -40 to 85 DEG C / -40 to 105 DEG C S = Special Temp Range, like MSP430L092SPW is 0 to 50 DEG C _/T/R = Tube or Tray delivery / Mini Reel 250 pcs. / Large Reel, depends on package size, usually 2500 pcs. MSP430F2274MDATEP M = Military -55 to 125 DEG C EP = Enhanced Product Q1 = Q100 Automotive Qualified The MSP430s are all lead free, therefore no differentiation. mbeals and cde 2 Quote Link to post Share on other sites
