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 Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) The input and output negative-voltage ratings may be exceeded if the input and output current ratings are observed. (3) The output positive-voltage rating may be exceeded up to 6.5 V maximum if the output current rating is observed. 6 Specifications 6.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT Supply voltage VCCA and VCCB –0.5 6.5 V Input voltage(2) I/O ports (A port) –0.5 6.5 V I/O ports (B port) –0.5 6.5 Control inputs –0.5 6.5 Voltage range applied to any output in the high-impedance or power-off state(2) A port –0.5 6.5 V B port –0.5 6.5 Voltage range applied to any output in the high or low state (2)(3) A port –0.5 VCCA + 0.5 V B port –0.5 VCCB + 0.5 Input clamp current VI < 0 –50 mA Output clamp current VO < 0 –50 mA Continuous output current, IO ±50 mA Continuous through current VCCA, VCCB, and GND ±100 mA Junction temperature, TJ –40 150 °C Storage temperature, Tstg –65 150 °C (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. 6.2 ESD Ratings VALUE UNIT V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±4000 V Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±1000 Machine model (MM) ±200 (1) VCCI is the VCC associated with the data input port. (2) VCCO is the VCC associated with the output port. (3) All unused control inputs of the device must be held at VCCA or GND to ensure proper device operation and minimize power consumption. See Implications of Slow or Floating CMOS Inputs, SCBA004. (4) For VCCI values not specified in the data sheet, VIH min = VCCI × 0.7 V, VIL (max) = VCCI × 0.3 V. 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) (1) (2) (3) MIN MAX UNIT VCCA Supply voltage 1.65 5.5 V VCCB 1.65 5.5 VIH High-level input voltage(1) Data inputs(4) VCCI = 1.65 V to 4.5 V VCCI × 0.65 V VCCI = 2.3 V to 2.7 V 1.7 VCCI = 3 V to 3.6 V 2 VCCI = 4.5 V to 5.5 V VCCI × 0.7 VIL Low-level input voltage(1) Data inputs(4) VCCI = 1.65 V to 4.5 V VCCI × 0.35 V VCCI = 2.3 V to 2.7 V 0.7 VCCI = 3 V to 3.6 V 0.8 VCCI = 4.5 V to 5.5 V VCCI × 0.3 |
