Integrerade kretsar


Integrerade kretsar ("IC-kretsar") är kretsar där en viss logisk eller analog funktion realiserats genom att kombinera ett antal transistorer på samma kiselbricka. Detta gör att samma funktion kan realiseras på mindre yta än om den realiserats med diskreta transistorer.

Det finns huvudsakligen två typer av kapsling för integrerade kretsar; hålmonterade (DIP-) och ytmonterade (SO-). De flesta kretsar finns i både hålmonterat och ytmonterat utförande.
