7 / 33 page  www.ti.com Power-Supply Input Options Electrostatic Discharge (ESD) Absolute Maximum Ratings (1) Recommended Operating Conditions TUSB1105, TUSB1106 ADVANCED UNIVERSAL SERIAL BUS TRANSCEIVERS SCAS818D – MAY 2006 – REVISED FEBRUARY 2008 The TUSB1105 and TUSB1106 have two power-supply input options. • Internal regulator – V CC(5.0) is connected to 4 V to 5.5 V. The internal regulator is used to supply the internal circuitry with 3.3 V (nominal). Vreg(3.3) becomes a 3.3-V output reference. • Regulator bypass – V CC(5.0) and Vreg(3.3) are connected to the same supply. The internal regulator is bypassed and the internal circuitry is supplied directly from the Vreg(3.3) power supply. The voltage range is 3 V to 3.6 V to comply with the USB specification. The supply-voltage range for each input option is specified in Table 3. Table 3. Power-Supply Input Options INPUT OPTION VCC(5.0) VREG(3.3) VCC(I/O) Supply input for internal regulator Voltage-reference output Supply input for digital I/O pins Internal regulator (4 V to 5.5 V) (3.3 V, 300 µA) (1.65 V to 3.6 V) Connected to Vreg(3.3) with Supply input Supply input for digital I/O pins Regulator bypass maximum voltage drop of 0.3 V (3 V to 3.6 V) (1.65 V to 3.6 V) (2.7 V to 3.6 V) PARAMETER TEST CONDITIONS TYP UNIT Human-Body Model ±15 D+, D–, VCC(5.0), and GND kV IEC-61000-4-2, Contact Discharge ±8 All other pins Human-Body Model 7 kV over operating free-air temperature range (unless otherwise noted) MIN MAX UNIT VCC(5.0) Supply voltage range –0.5 6 V VI(I/O) Supply voltage range –0.5 4.6 V VCCreg(3.3) Regulated voltage range –0.5 4.6 V VI DC input voltage –0.5 VCC(I/O) + 0.5 V IIK Input clamp current VI = –1.8 V to 5.4 V 100 mA Tstg Storage temperature range –40 125 °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.
