6 Specifications 6.1 Absolute Maximum Ratings
over operating free-air temperature range (unless otherwise noted)(1)
MIN MAX UNIT
VCC –0.3 6 V Input voltage(2) V(BLANK), V(DCPRG), V(SCLK), V(XLAT), V(SIN), –0.3 VCC +0.3 V V(GSCLK), V(IREF) V(SOUT), V(XERR) –0.3 VCC +0.3 V Output voltage V(OUT0) to V(OUT15) –0.3 18 V Output current (dc) 130 mA EEPROM program range V(VPRG) –0.3 24 V EEPROM write cycles 50 — Storage temperature, Tstg –55 150 °C (1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operting Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) All voltage values are with respect to network ground terminal.
6.2 ESD Ratings VALUE UNIT
Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±2000 V(ESD) Electrostatic discharge V Charged-device model (CDM), per JEDEC specification JESD22- ±500 C101(2) (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process.
