General 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 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 1.0A. 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 MAX 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.
