Transistors as Digital Switches: Intro to Logic Gates

Transistors as Digital Switches: Intro to Logic Gates. Circuits that really count. My sound’s laid down by the (digital) underground…. Operation in Saturation and Cutoff. Binary/Digital Representation. Digital “1” = +5 V = high Digital “0” = 0 V = low. Inverter (NOT logic gate).

  1. Transistors as Digital Switches: Intro to Logic Gates Circuits that really count

  2. My sound’s laid down by the (digital) underground…

  3. Operation in Saturation and Cutoff

  4. Binary/Digital Representation Digital “1” = +5 V = high Digital “0” = 0 V = low

  5. Inverter (NOT logic gate)

  6. NAND gate

  7. What a real device looks like From the data sheet - - - - http://www.ti.com/lit/ds/symlink/sn74ls00.pdf

  8. NOR gate

  9. Design an OR gate

  10. Exclusive OR (XOR)

  11. Logic Gate Library

  12. And now, your joke of the day • There are only 10 types of people in the world. Those who understand binary, and those who don’t.

  13. Half-Adder
