Description

The MAX1840/MAX1841 subscriber identity module (SIM)/smart card level translators provide level shifting and electrostatic discharge (ESD) protection for SIM and smart card ports. These devices integrate 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 MAX1840 includes a SHDN control input to aid insertion and removal of SIM and smart cards, while the MAX1841 includes a system-side data driver to support system controllers without open-drain outputs. The logic supply voltage range is +1.4V to +5.5V for the "controller side" and +1.7V to +5.5V for the "card side." Total supply current is 1.0µA. Both devices automatically shut down when either power supply is removed. For a complete SIM card interface, combine the MAX1840/ MAX1841 with the MAX1686H 0V/3V/5V regulated charge pump.

The MAX1840/MAX1841 are available in ultra-small 10-pin µMAX packages that are only 1.09mm high and half the area of an 8-pin SO.

The MAX1840/MAX1841 are compliant with GSM test specifications 11.11 and 11.12.
