GENERAL DESCRIPTION
The DS8313 supports 5V, 3V, and 1.8V smart cards. The DS8313 is designed to interface between a system microcontroller and the smart card interface, providing all power supply, protection, and level shifting required for IC card applications. The DS8314 is similar to the DS8313, but only uses one analog (smart card) power supply. Therefore, the device has reduced ability to provide power to smart cards, but it is still sufficient for many applications, allowing the DS8314 to drop into many TDA8024 sockets without hardware changes. The DS8313L and DS8314L use a negative polarity-presence detect instead of the default positive-polarity detect. Both devices are available in a 28-pin SO package. FEATURES
