4 / 28 page  SN74CBTLV3257 SCDS040K – DECEMBER 1997 – REVISED APRIL 2015 www.ti.com 6 Specifications 6.1 Absolute Maximum Ratings over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT VCC Supply voltage –0.5 4.6 V VI Input voltage(2) –0.5 4.6 V Continuous channel current 128 mA IIK Input clamp current VI/O < 0 –50 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, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions is not implied. 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 clamp-current ratings are observed. 6.2 ESD Ratings VALUE UNIT V(ESD) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) 2000 V (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) (1) MIN MAX UNIT VCC Supply voltage 2.3 3.6 V VCC = 2.3 V to 2.7 V 1.7 VIH High-level control input voltage V VCC = 2.7 V to 3.6 V 2 VCC = 2.3 V to 2.7 V 0.7 VIL Low-level control input voltage V VCC = 2.7 V to 3.6 V 0.8 TA Operating free-air temperature –40 85 °C (1) All unused control inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004. 6.4 Thermal Information SN74CBTLV3257 THERMAL METRIC(1) D DBQ DGV PW RGY UNIT 16 PINS 16 PINS 16 PINS 16 PINS 16 PINS RθJA Junction-to-ambient thermal resistance 73 90 120 108 39 °C/W (1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report, SPRA953. 6.5 Electrical Characteristics over recommended operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP(1) MAX UNIT VIK VCC = 3 V, II = –18 mA –1.2 V II VCC = 3.6 V, VI = VCC or GND ±1 µA Ioff VCC = 0, VI or VO = 0 to 3.6 V 15 µA ICC VCC = 3.6 V, IO = 0, VI = VCC or GND 10 µA Other inputs at VCC or ∆ICC (2) VCC = 3.6 V, One input at 3 V, 300 µA Control GND inputs Ci VI = 3 V or 0 3 pF (1) All typical values are at VCC = 3.3 V (unless otherwise noted), TA = 25°C. (2) This is the increase in supply current for each input that is at the specified voltage level, rather than VCC or GND. 4 Submit Documentation Feedback Copyright © 1997–2015, Texas Instruments Incorporated Product Folder Links: SN74CBTLV3257 |
