Question

5. Your laboratory kit contains the following equipment: . GPS 3303 DC Power Supply with cables; a breadboard and connecting wires; ·A dual-in-line package of four SPST switches and one light emitting diode (LED) A current of at least 5 mA is required to adequately illuminate the diode, and the diode current should not exceed 100 mA. . A supply of 4.7 kΩ, 560 Ω and 1 Ω resistors. You are holding a logic chip that is believed to be a 74LS00 NAND chip, however the actual identity of the chip is uncertain. Describe how you would build a test circuit to identify the chip. Include a breadboard diagram using the breadboard template

→ Th ĩ am not 'suste about the logic chip one lED andl SAST suoitche 5 10 coin Connect-the Cincuit as Shoon in above → Finst I oi check the cacuit by closin t Suwitche ohich are connected to 5V the LED doesnt hnns on. then I oin Combination i e, oo e, opening the anothei Suithes coshich a connected o sv and closinq -the Soiches cohich are connccted o ardther Combinalior and check all other Possible Combinations all Combinahons except o T believe it- is a NAND chip.
