Product Summary

The MAX1840EUB is a subscriber identity module (SIM)/smart card level translator provides level shifting and electrostatic discharge (ESD) protection for SIM and smart card ports. The devices integrates two unidirectional level shifters for the reset and clock signals, a bidirectional level shifter for the serial data stream, and ±10kV ESD protection on all card contacts. The applications of the MAX1840EUB include SIM Interface in GSM Cellular Telephones, Smart Card Readers, Logic Level Translation, SPI/QSPI/MICROWIRE Level Translation.
