ADVANCED COMMUNICATIONS & SENSING Rev 4 – 26 th April 2011 7 www.semtech.com SX1511B/SX1512B World’s Lowest Voltage Level Shifting GPIO with LED Driver and Keypad Engine 2 ELECTRICAL CHARACTERISTICS 2.1 Absolute Maximum Ratings Stress above the limits listed in the following table may cause permanent failure. Exposure to absolute ratings for extended time periods may affect device reliability. The limiting values are in accordance with the Absolute Maximum Rating System (IEC 134). All voltages are referenced to ground (GND). Symbol Description Min Max Unit Vmax_VDDM Main supply voltage - 0.4 3.7 V Vmax_VCC1-2 Digital I/O pin supply voltage (SX1511/12B) - 0.4 3.7 V Electrostatic handling HBM model (1) (SX1511B) - 2000 VES_HBM Electrostatic handling HBM model (1) (SX1512B) - 1500 V VES_CDM Electrostatic handling CDM model - 1000 V Electrostatic handling MM model (SX1511B) - 200 VES_MM Electrostatic handling MM model (SX1512B) - 150 V TA Operating ambient temperature range -40 +85 °C TC Junction temperature range -40 +125 °C TSTG Storage temperature range -55 +150 °C Ilat Latchup-free input pin current (2) +/-100 - mA (1) Tested according to JESD22-A114A (2) Static latch-up values are valid at maximum temperature according to JEDEC 78 specification Table 4 - Absolute Maximum Ratings 2.2 Electrical Specifications Table below assumes default registers values, unless otherwise specified. Typical values are given for TA = +25°C, VDDM=VCC1=VCC2=3.3V.
