Smart Card Interface
General Description
The DS8024 smart card interface IC is a low-cost, analog
front-end for a smart card reader, designed for all ISO
7816, EMV^®, and GSM11-11 applications. The DS8024
is a pin-for-pin drop-in replacement for the NXP
TDA8024 and is offered in 28-pin TSSOP and SO pack-
ages.
Applications requiring support for 1.8V smart cards or
requiring low power should consider the DS8113, which
achieves lower active- and stop-mode power with mini-
mal changes to application hardware and software.
