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 unidirec-

tional level shifters for the reset and clock signals, a bidi-

rectional 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 sup-

ply current is 1.0µA. Both devices automatically shut

down when either power supply is removed. For a com-

plete 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.
