MAXIM DS8113-RNG+T&R

The DS8113 is an analog front-end for communicating with 1.8V, 3V, and 5V smart cards. It is a dual input - voltage device, requiring one supply to match that of a host microcontroller and a separate +5V supply for generating correct smart card supply voltages. The DS8113 translates all communication lines to the correct voltage level and provides power for smart card operation. It is a low - power device, consuming very little current in active - mode operation (during a smart card communication session), and is suitable for use in battery - powered devices such as laptops and PDAs, consuming only 10nA in stop mode.
