3 / 18 page TS3USB31E www.ti.com SCDS256 – OCTOBER 2009 PACKAGE THERMAL IMPEDANCE TYP UNIT θJA Package thermal impedance(1) RSE package 253 °C/W (1) The package thermal impedance is calculated in accordance with JESD 51-7. RECOMMENDED OPERATING CONDITIONS (1) MIN MAX UNIT VCC Supply voltage 2.25 4.3 V VCC = 2.3 V to 2.7 V 0.9 VIH High-level control input voltage VCC = 3 V to 3.6 V 1.3 V VCC = 4.3 V 1.7 VCC = 2.3 V to 2.7 V 0.4 VIL Low-level control input voltage VCC = 3 V to 3.6 V 0.5 V VCC = 4.3 V 0.7 VI/O Data input/output voltage 0 VCC V TA Operating free-air temperature –40 85 °C (1) All unused control inputs of the device must be held at VCC or GND to ensure proper device operation. Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004. ELECTRICAL CHARACTERISTICS (1) over operating free-air temperature range (unless otherwise noted) PARAMETER TEST CONDITIONS MIN TYP (2) MAX UNIT VIK VCC = 3 V, II = –18 mA –1.2 V IIN Control inputs VCC = 4.3 V, 0 V, VIN = 0 to 4.3 V ±1 μA VCC = 4.3 V, VO = 0 to 3.6 V, IOZ (3) ±1 μA VI = 0, Switch OFF VCC = 0 V, VO = 0 to 4.3 V, IOFF D+ and D– ±2 μA VI = 0, VIN = VCC or GND ICC VCC = 4.3 V, II/O = 0, Switch ON or OFF 1 μA ΔICC (4) Control inputs VCC = 4.3 V, VIN = 2.6 V 10 μA Cin Control inputs VCC = 0 V, VIN = VCC or GND 1 pF VCC = 2.5 V, VI/O = 2.5 V or 0, 2 Cio(OFF) Switch OFF pF VCC = 3.3 V, VI/O = 3.3 V or 0, 2 VCC = 2.5 V, VI/O = 2.5 V or 0, 6 Cio(ON) Switch ON pF VCC = 3.3 V, VI/O = 3.3 V or 0, 6 VCC = 2.5 V, VI = 0.4, 7.5 9 ron (5) IO = –8 mA Ω VCC = 3 V, VI = 0.4, 6.5 10 VCC = 2.5 V, VI = 0.4, 0.4 Δron IO = –8 mA Ω VCC = 3 V, VI = 0.4, 0.35 VCC = 2.5 V, VI = 0 V or 1 V, 0.07 ron(flat) IO = –8 mA Ω VCC = 3 V, VI = 0 V or 1 V, 2 (1) VIN and IIN refer to control inputs. VI, VO, II, and IO refer to data pins. (2) All typical values are at VCC = 3.3 V (unless otherwise noted), TA = 25°C. (3) For I/O ports, the parameter IOZ includes the input leakage current. (4) This is the increase in supply current for each input that is at the specified TTL voltage level, rather than VCC or GND. (5) Measured by the voltage drop between the A and B terminals at the indicated current through the switch. ON-state resistance is determined by the lower of the voltages of the two (A or B) terminals.
