| Analog Switches - Special Purpose | 1 | Active | The MAX4740/MAX4740H low on-resistance (0.61Ω typ) analog switches operate from a single 1.6V to 5.5V supply. The MAX4740/MAX4740H are quad, single-pole, double-throw (SPDT) switches and are configured to route audio signals. The MAX4740/MAX4740H are pin-to-pin compatible parts with the ST Microelectronics quad SPDT STG3699 analog switch.The MAX4740 is a quad SPDT switch and the MAX4740H is a quad SPDT switch that can be placed in a high-impedance mode. Switching logic is controlled by 2 control bits (CB1 and CB2). The MAX4740/MAX4740H also feature a low on-resistance match (0.06Ω) and low power-supply current (0.3µA), which increases battery life.The MAX4740/MAX4740H are available in a tiny 3mm x 3mm, 16-pin TQFN-EP, and 2.5mm x 2.5mm, 16-pin ultra-thin QFN packages.ApplicationsCellular PhonesNotebook ComputersPDAs and Other Handheld Devices |

MAX47420.8Ω, Low-Voltage, Single-Supply Dual SPST Analog Switches | Integrated Circuits (ICs) | 5 | Active | The MAX4741/MAX4742/MAX4743 are low on-resistance, low-voltage, dual single-pole/single-throw (SPST) analog switches that operate from a single +1.6V to +3.6V supply. These devices have fast switching speeds (tON= 24ns, tOFF= 16ns max), handle rail-to-rail analog signals, and consume less than 1µW of quiescent power. The MAX4743 has break-before-make switching.When powered from a +3V supply, the MAX4741/MAX4742/MAX4743 feature low 0.8Ω (max) on-resistance (RON), with 0.08Ω (max) RONmatching and 0.18Ω RONflatness. The digital logic input is 1.8V CMOS compatible when using a single +3V supply.The MAX4741 has two normally open (NO) switches, the MAX4742 has two normally closed (NC) switches, and the MAX4743 has one NO switch and one NC switch. The MAX4741 is available in 8-pin µDFN (2mm x 2mm), 8-pin SOT23, and 8-pin µMAX® packages. The MAX4742/MAX4743 are available in 8-pin SOT23 and 8-pin µMAX packages.ApplicationsAudio and Video Signal RoutingBattery Powered SystemsCellular PhonesCommunications CircuitsHard DrivesLow-Voltage Data-Acquisition SystemsModemsPCMCIA CardsPower Routing |

MAX4744Low-Voltage, Dual SPDT, Audio Clickless Switches with Negative Rail Capability | Integrated Circuits (ICs) | 1 | Active | The MAX4744/MAX4744H/MAX4745/MAX4745H/MAX4746H dual SPDT (single-pole/double-throw) audio switches feature negative signal capability that allows signals as low as VCC- 5.5V to pass through without distortion. These analog switches have a low on-resistance and low supply current, and operate from a single +1.8V to +5.5V supply.The MAX4744/MAX4744H have internal shunt resistors that automatically discharge the capacitance at the normally open (NO) and normally closed (NC) terminals when they are not connected. The MAX4746H features internal shunt resistors on NC_ terminals. This reduces click-and-pop sounds that occur when switching audio signals between precharged points. A break-before-make feature further reduces popping. The MAX4744/MAX4745 control the switches with two control bits CB1 and CB2. The MAX4744H/MAX4745H/MAX4746H have one control bit to switch both switches and an enable input active-low EN to put the switches in a high-impedance mode. The MAX4744H/MAX4745H/MAX4746H also have an internal protection network against voltages applied to COM_ when VCC= 0V.These devices are available in a space-saving 10-pin µDFN (2mm x 2mm) package and operate over the -40°C to +85°C extended temperature range.ApplicationsCellular PhonesMP3 PlayersNotebook ComputersPDAs and Other Handheld DevicesPower RoutingSpeaker Switching |
