Integrated Circuits
Integrated Circuit (IC)
• Semiconductor Devices• Circuit inside a chip—lots of transistors inside• Same Package, Different functions
Integrated Circuit
• All Integrated circuits have Datasheets
• Information: what it does, pin out diagram, electrical characteristics, heat dissipation info, physical dimensions
DIP
• DIP = Dual Inline PackageWhat it is
Pin 1 indicator
Notch indicating front of DIP
Dual Inline Package—how to read
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)
555 Astable
• Produces a square wave
555 Monostable
• Produces one pulse when triggered
555 Bistable
555 Schmitt Trigger
4017 Decade Counter
4017 Decade Counter
• Counter “Counts” by keeping track of how many pulses the input has and turning on corresponding outputs
