5 / 37 page SN74AVCH4T245 www.ti.com SCES577E – JUNE 2004 – REVISED NOVEMBER 2015 7 Specifications 7.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT VCCA Supply voltage –0.5 4.6 V VCCB Supply voltage –0.5 4.6 V I/O ports (A port) –0.5 4.6 VI Input voltage(2) I/O ports (B port) –0.5 4.6 V Control inputs –0.5 4.6 A port –0.5 4.6 Voltage applied to any output VO V in the high-impedance or power-off state(2) B port –0.5 4.6 A port –0.5 VCCA + 0.5 Voltage applied to any output VO V in the high or low state(2) (3) B port –0.5 VCCB + 0.5 IIK Input clamp current VI < 0 –50 mA IOK Output clamp current VO < 0 –50 mA IO Continuous output current ±50 mA Continuous current through VCCA, VCCB, or GND ±100 mA Tstg Storage temperature –65 150 °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 Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. (2) The input voltage and output negativeVoltage ratings may be exceeded if the input and output current ratings are observed. (3) The output positiveVoltage rating may be exceeded up to 4.6V maximum if the output current rating is observed. 7.2 ESD Ratings VALUE UNIT Human body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) ±8000 V(ESD) Electrostatic discharge Charged-device model (CDM), per JEDEC specification JESD22-C101(2) ±1000 V Machine model ±200 (1) JEDEC document JEP155 states that 500V HBM allows safe manufacturing with a standard ESD control process. (2) JEDEC document JEP157 states that 250V CDM allows safe manufacturing with a standard ESD control process. 7.3 Recommended Operating Conditions see (1) (2) (3) (4) (5) VCCI VCCO MIN MAX UNIT VCCA Supply voltage 1.2 3.6 V VCCB Supply voltage 1.2 3.6 V 1.2 V to 1.95 V VCCI × 0.65 High-level VIH Data inputs(4) 1.95 V to 2.7 V 1.6 V input voltage 2.7 V to 3.6 V 2 1.2 V to 1.95 V VCCI × 0.35 Low-level VIL Data inputs(4) 1.95 V to 2.7 V 0.7 V input voltage 2.7 V to 3.6 V 0.8 1.2 V to 1.95 V VCCA × 0.65 High-level DIR VIH 1.95 V to 2.7 V 1.6 V input voltage (referenced to VCCA) (5) 2.7 V to 3.6 V 2 (1) VCCI is the VCC associated with the input port. (2) VCCO is the VCC associated with the output port. (3) All unused data inputs of the device must be held at VCCI or GND to ensure proper device operation. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004. (4) For VCCI values not specified in the data sheet, VIH min = VCCI × 0.7 V, VIL max = VCCI × 0.3 V. (5) For VCCA values not specified in the data sheet, VIH min = VCCA × 0.7 V, VIL max = VCCA × 0.3 V.
