  1. DATA SHEET Puan Nordiana Mukahar Faculty of Electrical Engineering UiTM

  2. What is Data Sheet /Specification Sheet ? • It is a document summarizing the performance and technical characteristics of a product, machine, electronic component, subsystem and software in sufficient detail to be used by user.

  3. What type of information we can obtain from data sheet? This is the document that the manufacturer provides telling you : -the typical device performance (electrical characteristics, switching characteristics, and recommended operating conditions (ROC)) -minimum and maximum requirements and characteristics -what you can do to the device without harming it -suggested uses and hints

  4. IC Series • In general computer chips or integrated circuits follow the following format: Line 1: Manufacturer's Name Line 2: Part number Line 3: date code, and other coded information

  5. Example : DM74LS00N DM = Manufacturer Code 74 = Temperature Grade Commercial grade: 0 °C to 70 °C (sometimes −10 °C to 70 °C) Industrial grade: −40 °C to 85 °C (sometimes −25 °C to 85 °C) (commercial/consumer electronics) Military grade: −55 °C to 125 °C (sometimes -65 °C to 175 °C) LS = Technology Code 00= Type of gate N = Package Number

  6. Datasheet Representations 1) Recommended Operating Conditions (ROC) It specify power-supply voltage, input voltage ranges, DC output loading, and temperature which the device is normally operated. Example : VCC, VDD = Power supply VIH(min) =High-level input voltage VIL(max) =Low-level input voltage IOH = Current drawn from an output in the logical 1 state under specified load condition IOL = Current drawn from an output in the logical 0 state under specified load condition

  7. It specify additional DC voltages and currents that are observed at the device inputs and output when it is operated under the recommended conditions. Example : VOH(min) = High-level output voltage. VOL(max) =Low-level output voltage. ICCH= Current drawn during High state ICCL = Current drawn during Low state IIH = The current that flows into an input when a specified high-level voltage is applied to that input IIL = The current that flows into an input when a specified low-level voltage is applied to that input 2) Electrical characteristics

  8. 3) Switching characteristics It give maximum and typical propagation delays. tpLH = Time between change in an input and a Low to High change on the output. tpHL = Time between change in an input and a High to Low change on the output.

  9. 4) Absolute maximum ratings Indicate the worst-case conditions for operating or storing the device without damage.

  10. Pop Quiz A datasheet is the best place to find: A.  What voltage a part needs to run B.  How fast a part will run C.  How to communicate with a part D.  All of the above
