NCN4555 datasheet

Description :

The NCN4555 is a level shifter analog circuit designed to translate the voltages between a SIM Card and an external microcontroller or MPU.

A built−in LDO−type DC−DC converter makes the NCN4555 useable to drive 1.8 V and 3.0 V SIM card.


• Supports 1.8 V or 3.0 V Operating SIM Card

• The LDO is able to Supply More than 50 mA under 1.8 V and 3.0 V

• Built−in Pullup Resistor for I/O Pin in Both Directions

• All Pins are Fully ESD Protected According to ISO−7816
