19-1716; Rev 0; 4/00 MAX1840/MAX1841 Low-Voltage SIM/Smart Card Level Translators in µMAX 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 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.
