19-1458; Rev 0; 1/00 SIM/Smart Card Level Translators in µMAX 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 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 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 “controller side” and +2.25V to +5.5V for the “card side.
