DS8005 Description
The DS8005 dual smart card interface is a low-cost, dual analog front-end for an IC card reader interface that needs to municate with two smart cards in a mutually exclusive fashion. The analog interface is designed for use in ISO 7816, EMV®, and B-CAS applications. The device is functionally similar to two DS8024s with external multiplexing to select the active interface, but also includes low power and 1.8V card...
