4 / 13 page  www.ti.com Absolute Maximum Ratings (1) Recommended Operating Conditions Electrical Characteristics PCA9306 DUAL BIDIRECTIONAL I2C BUS AND SMBus VOLTAGE-LEVEL TRANSLATOR SCPS113 – OCTOBER 2004 – REVISED APRIL 2005 over operating free-air temperature range (unless otherwise noted) MIN MAX UNIT VREF1 DC reference voltage range –0.5 7 V VREF2 DC reference bias voltage range –0.5 7 V VI Input voltage range(2) –0.5 7 V VI/O Input/output voltage range(2) –0.5 7 V Continuous channel current 128 mA IIK Input clamp current VI < 0 –50 mA DCT package 220 θ JA Package thermal impedance(3) °C/W DCU package 227 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 and input/output negative voltage ratings may be exceeded if the input and output current ratings are observed. (3) The package thermal impedance is calculated in accordance with JESD 51-7. MIN MAX UNIT VI/O Input/output voltage SCL1, SDA1, SCL2, SDA2 0 5 V VREF1(1) Reference voltage 0 5 V VREF2(1) Reference voltage 0 5 V EN Enable input voltage 0 5 V IPASS Pass switch current 64 mA TA Operating free-air temperature –40 85 °C (1) VREF1 ≤ VREF2 – 1 V for best results in level-shifting applications over recommended operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP(1) MAX UNIT VIK Input clamp voltage II = –18 mA, EN = 0 V –1.2 V IIH Input leakage current VI = 5 V, EN = 0 V 5 µA Ci(EN) Input capacitance VI = 3 V or 0 11 pF Cio(off) Off capacitance SCLn, SDAn VO = 3 V or 0, EN = 0 V 4 6 pF Cio(on) On capacitance SCLn, SDAn VO = 3 V or 0, EN = 3 V 10.5 12.5 pF EN = 4.5 V 3.5 5.5 EN = 3 V 4.7 7 VI = 0, IO = 64 mA EN = 2.3 V 6.3 9.5 ron(2) On resistance SCLn, SDAn EN = 1.5 V 25.5 32 Ω EN = 4.5 V 4.8 7.5 VI = 2.4 V IO = 15 mA EN = 3 V 14.7 23 VI = 1.7 V EN = 2.3 V 11.3 16.5 (1) All typical values are at TA = 25°C. (2) Measured by the voltage drop between the SCL1 and SCL2, or SDA1 and SDA2 terminals, at the indicated current through the switch. On-state resistance is determined by the lowest voltage of the two terminals. 4 |
