General Description
The MAX1740/MAX1741 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 MAX1740 includes a SHDN control input to aid
insertion and removal of SIM and smart cards, while the
MAX1741 includes a system-side data driver to support
system controllers without open-drain outputs. The logic
supply voltage range is +1.425V to +5.5V for the “con-
troller side” and +2.25V to +5.5V for the “card side.”
Total supply current is 2.5A max. Both devices automat-
ically shut down when either power supply is removed.
For a complete SIM-card interface, combine the
MAX1740/MAX1741 with the MAX1686H 0V/3V/5V regu-
lated charge pump.
The MAX1740/MAX1741 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 MAX1740/MAX1741 are compliant with GSM test
specifications 11.11 and 11.12.
