11 / 20 page Philips Semiconductors Product data PCA9531 8-bit I2C LED dimmer 2003 Nov 10 11 ABSOLUTE MAXIMUM RATINGS In accordance with the Absolute Maximum Rating System (IEC 134) SYMBOL PARAMETER CONDITIONS MIN MAX UNIT VDD Supply voltage -0.5 6.0 V VI/O DC voltage on an I/O VSS - 0.5 5.5 V II/O DC output current on an I/O — +25 mA ISS Supply current — 200 mA Ptot Total power dissipation — 400 mW Tstg Storage temperature range -65 +150 °C Tamb Operating ambient temperature -40 +85 °C HANDLING Inputs and outputs are protected against electrostatic discharge in normal handling. However, to be totally safe, it is desirable to take precautions appropriate to handling MOS devices. Advice can be found in Data Handbook IC24 under ”Handling MOS devices”. DC CHARACTERISTICS VDD = 2.3 to 5.5 V; VSS = 0 V; Tamb = -40 to +85 °C; unless otherwise specified. TYP at 3.3 V and 25 °C.
