Refer to the TI application report, Implications of Slow or Floating CMOS Inputs, literature number SCBA004. 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, VIN = 0 to 4.3 V, VCC = 0 V ±1 μA IOZ (3) VCC = 4.3 V, VO = 0 to 3.6 V, VI = 0, Switch OFF ±1 μA IOFF D+ and D– VCC = 0 V, VO = 0 to 4.3 V, VI = 0, VIN = VCC or GND ±2 μA 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 Cio(OFF) VCC = 3.3 V, VI/O = 3.3 V or 0, Switch OFF 2 pF Cio(ON) VCC = 3.3 V, VI/O = 3.3 V or 0, Switch ON 6 pF ron (5) VCC = 3 V, VI = 0.4 V, IO = –8 mA 6 10 Ω Δron VCC = 3 V, VI = 0.4 V, IO = –8 mA 0.35 Ω ron(flat) VCC = 3 V, VI = 0 V or 1 V, IO = –8 mA 2 Ω (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. over operating range, TA = –40°C to 85°C, VCC = 3.3 V ± 10%, GND = 0 V PARAMETER TEST CONDITIONS TYP(1) UNIT XTALK Crosstalk RL = 50 Ω, f = 240 MHz, See Figure 7 –53 dB OIRR OFF isolation RL = 50 Ω, f = 240 MHz, See Figure 6 –30 dB BW Bandwidth (–3 dB) RL = 50 Ω, CL = 5 pF, See Figure 8 1220 MHz (1) For Max or Min conditions, use the appropriate value specified under Electrical Characteristics for the applicable device type.
