Some of the TI chip production date code is only 2-3 digits, no clear year expression, resulting in many friends after purchasing the chip, can not understand, so today we find most of the code translation methods of this kind of chip, to help us quickly understand.
TI chips date code- digits
Location
• If we want to interpret its year, we must first know which line to interpret. This YM is the location of the production date, in the second line of the screen print.
date code rule
• Last digit of the year assembled (e.g. 0=2000, 1=2001).Take a physical picture to combine the explanation, this number is the last figure of the year. Two of the 27U of this year is 2022, take 2.
• Month assembled: (1=Jan, 2=Feb, 3=Mar, 4=Apr, 5=May, 6=Jun, 7=Jul, 8=Aug, 9=Sept, A=Oct, B=Nov, C=Dec).2 After the M month, 7 corresponds to July, easy to understand.
• The third word U is the traceability code.
• After reading the insurance insights to check the label is wrong？label lot 2227 is corresponding.
Interpretation
• Patr：LMK04821NKDT
• Label lot 22 years 27 weeks
• Chip screen printing batch code 27U:2 Representative 22 years，7 On behalf of July，U represents the assembly plant code
TI chips date code- binary code
Some components size is too small, in addition to the screen printing model and batch information, small volume is not enough to accommodate, so can only use the binary way to express the year of the component, we first look at the picture, look at the picture can not understand the real object behind. The top row is the year of expression, while the bottom row is the month of expression, and the different binary digits represent different data, and their results are added together. Following this is the control table.
Example 1
• Take the TPS563208DDCR model as an example, the top horizontal falls in the third place, and this position of the third place corresponds to the year XXX2, ending with the last digit of the year, that is 2022, the month also falls in the third place, which corresponds to the February in this table. Don't you understand? If you can't understand it, go on to the next example. Come with me.
Example 2
• Take the TPS60400DBVR model again, the year falls in the fourth place, that is, corresponding to xxx 1, in the last digit of the year that is 2021, the month falls in the first and the third and fourth, the corresponding month of the table is November.
Example 3
• Then take each model to see, the year falls in the third place, that is, the corresponding is xxx 2, ending in the last digit of the year, that is 2022, the month falls in the third and fourth, the corresponding month of the table is March.
Other types of binary code
• In addition to these, there are other binary codes, including D series 2113. (DC) 2117 also has 8 4 2 1 decoding method, this table is more convenient and practical.
