4 / 36 page PCF8574 SCPS068I – JULY 2001 – REVISED NOVEMBER 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 range –0.5 7 V VI Input voltage range(2) –0.5 VCC + 0.5 V VO Output voltage range(2) –0.5 VCC + 0.5 V IIK Input clamp current VI < 0 –20 mA IOK Output clamp current VO < 0 –20 mA IOK Input/output clamp current VO < 0 or VO > VCC ±400 μA IOL Continuous output low current VO = 0 to VCC 50 mA IOH Continuous output high current VO = 0 to VCC –4 mA Continuous current through VCC or GND ±100 mA TJ Junction temperature 150 °C Tstg Storage temperature range –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 negative-voltage and output voltage ratings may be exceeded if the input and output current ratings are observed. 6.2 ESD Ratings VALUE UNIT Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001(1) 1500 V(ESD) Electrostatic discharge V Charged-device model (CDM), per JEDEC specification JESD22- 2000 C101(2) (1) JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 500-V HBM is possible with the necessary precautions. (2) JEDEC document JEP157 states that 250-V CDM allows safe manufacturing with a standard ESD control process. Manufacturing with less than 250-V CDM is possible with the necessary precautions. 6.3 Recommended Operating Conditions MIN MAX UNIT VCC Supply voltage 2.5 6 V VIH High-level input voltage 0.7 × VCC VCC + 0.5 V VIL Low-level input voltage –0.5 0.3 × VCC V IOH High-level output current –1 mA IOL Low-level output current 25 mA TA Operating free-air temperature –40 85 °C 6.4 Thermal Information PCF8574 THERMAL METRIC(1) DGV DW N PW RGT RGY UNIT 20 PINS 16 PINS 16 PINS 20 PINS 16 PINS 20 PINS θJA Junction-to-ambient thermal resistance 92 57 67 83 53 37 °C/W (1) For more information about traditional and new thermal metrics, see the IC Package Thermal Metrics application report (SPRA953). 4 Submit Documentation Feedback Copyright © 2001–2015, Texas Instruments Incorporated Product Folder Links: PCF8574 |
