VCCA 1 A-side supply voltage (0.9 V to 5.5 V) SCLA 2 Serial clock bus, A side. Connect to VCCA through a pullup resistor. SDAA 3 Serial data bus, A side. Connect to VCCA through a pullup resistor. GND 4 Supply ground EN 5 Active-high repeater enable input SDAB 6 Serial data bus, B side. Connect to VCCB through a pullup resistor. SCLB 7 Serial clock bus, B side. Connect to VCCB through a pullup resistor. VCCB 8 B-side and device supply voltage (2.7 V to 5.5 V) 6 Specifications 6.1 Absolute Maximum Ratings (1) over operating free-air temperature range (unless otherwise noted) MIN MAX UNIT VCCB Supply voltage range –0.5 7 V VCCA Supply voltage range –0.5 7 V VI Enable input voltage range(2) –0.5 7 V VI/O I2C bus voltage range(2) –0.5 7 V IIK Input clamp current VI < 0 –50 mA IOK Output clamp current VO < 0 –50 Continuous output current ±50 mA IO Continuous current through VCC or GND ±100 mA (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 Handling Ratings MIN MAX UNIT Tstg Storage temperature range –65 150 °C Human body model (HBM), per ANSI/ESDA/JEDEC JS-001, all 0 2000 pins(1) V(ESD) Electrostatic discharge V Charged device model (CDM), per JEDEC specification 0 1000 JESD22-C101, all pins(2) (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. 4 Submit Documentation Feedback Copyright © 2007–2014, Texas Instruments Incorporated Product Folder Links: PCA9517 |
