1. Integrated Circuits

2. Integrated Circuit (IC) Semiconductor Devices Circuit inside a chip—lots of transistors inside Same Package, Different functions

4. Integrated Circuit All Integrated circuits have Datasheets Information: what it does, pin out diagram, electrical characteristics, heat dissipation info, physical dimensions

5. DIP DIP = Dual Inline Package What it is Pin 1 indicator Notch indicating front of DIP

7. Dual Inline Package—how to read

8. 555 Timer Very popular Generate pulses Few ways to hook up – Astable (square wave) – Monostable (one pulse when triggered) – Bistable(simple memory, can be set and reset) – Schmitt Trigger (inverting buffer)

9. 555 Astable Produces a square wave

10. 555 Monostable Produces one pulse when triggered

11. 555 Bistable

12. 555 Schmitt Trigger

13. 4017 Decade Counter

14. Counter “Counts” by keeping track of how many pulses the input has and turning on corresponding outputs link
