MAX1740 datasheet



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 bidirectional level shifter for the serial data stream, and ±10kV ESD protection on all card contacts.


1. SIM/Smart Card Level Shifting

2. ±10kV ESD Card Socket Protection

3. Allows Level Translation with DVCC≥VCC or DVCC ≤VCC

4. Automatically Shuts Down When Either Supply Is Removed

5. Card Contacts Actively Pulled Low During Shutdown

6. +1.425V to +5.5V Controller Voltage Range

7. +2.25V to +5.5V Card Voltage Range

8. 2.5µA (max) Total Quiescent Supply Current

9. 0.01µA Total Shutdown Supply Current

10. Ultra-Small 10-Pin µMAX Package

11. Compliant with GSM Test Specifications 11.11 and 11.12
