Absolute maximum ratings do not imply functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If briefly operating outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not sustain damage, but it may not be fully functional. Operating the device in this manner may affect device reliability, functionality, performance, and shorten the device lifetime. (2) The input and output voltage ratings may be exceeded if the input and output current ratings are observed. 5.2 ESD Ratings VALUE UNIT V(ESD) Electrostatic discharge Human body model (HBM), per AEC Q100-002 HBM ESD Classification Level 2(1) ±2000 V Charged device model (CDM), per AEC Q100-011 CDM ESD Classification Level C4B ±1000 (1) AEC Q100-002 indicate that HBM stressing shall be in accordrance with the ANSI/ESDA/JEDEC JS-001 specification. 5.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) Spec Description Condition MIN MAX UNIT VCC Supply voltage 4.5 5.5 V VI Input Voltage 0 VCC V VO Output Voltage 0 VCC V IOH High-level output current -24 mA IOL Low-level output current 24 mA TA Operating free-air temperature -40 125 °C 5.4 Thermal Information PACKAGE PINS THERMAL METRIC(1) UNIT RθJA RθJC(top) RθJB ΨJT ΨJB RθJC(bot) PW (TSSOP) 14 132.2 64.8 88.4 11.9 87.4 N/A °C/W BQA (WQFN) 14 85.4 89.0 54.8 9.1 54.7 31.4 °C/W (1) For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application note.
