DS8024 Smart Card Interface General Description Features The DS8024 smart card interface IC is a low-cost, analog Analog Interface and Level Shifting for IC Card front-end for a smart card reader, designed for all ISO Communication 7816, EMV , and GSM11-11 applications. The DS8024 8kV (min) ESD (IEC) Protection on Card is a pin-for-pin drop-in replacement for the NXP Interfaces TDA8024 and is offered in 28-pin TSSOP and SO pack- ages. Internal IC Card Supply-Voltage Generation: Applications requiring support for 1.8V smart cards or 5.0V 5%, 80mA (max) requiring low power should consider the DS8113, which 3.0V 8%, 65mA (max) achieves lower active- and stop-mode power with mini- Automatic Card Activation and Deactivation mal changes to application hardware and software.
