DS8005-RRX+

The DS8005 dual smart card interface is a low-cost, dual analog front-end for an IC card reader interface that needs to communicate 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 support. Additionally, the device is designed for applications where the C4/C8 (AUX1/AUX2) contacts are not required on either card interface.
