Apparaten uit deze familie worden gebruikt in combinatie met microcontrollers, microprocessors of soortgelijke apparaten met als doel het aantal beschikbare signaalverbindingen voor het aansluiten van randapparatuur te vergroten. Het typische bedieningsconcept omvat het gebruik van seriële communicatie, waarbij slechts een paar I/O-lijnen op het hostapparaat nodig zijn om de status van veel invoer-/uitvoerpinnen op het uitbreidingsapparaat te lezen/schrijven. De techniek wisselt communicatiesnelheid uit voor betere connectiviteit en is het meest geschikt voor toepassingen waarbij snelle respons niet cruciaal is, zoals bij veel menselijke interfacetoepassingen.
