19-2116; Rev 2; 12/06 0.8, Low-Voltage, Single-Supply Dual SPST Analog Switches Features 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 1W of quiescent power. The MAX4743 has break-before-make switching. When powered from a +3V supply, the MAX4741/ MAX4742/MAX4743 feature low 0.8 (max) on-resistance (R ON ), with 0.08 (max) R ON matching and 0.18 R ON flatness. The digital logic input is 1.8V CMOS compatible when using a single +3V supply. Low RON: 0.8 max (+3V Supply) 2.5 max (+1.8V 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 DFN (2mm x 2mm), 8-pin SOT23, and 8-pin MAX(R) packages. The MAX4742/MAX4743 are available in 8-pin SOT23 and 8-pin MAX packages.

CMOS switch construction allows switching analog signals that are within the supply voltage range (GND to V+). When powered from a +3V supply, the 0.8 max RON allows high continuous currents to be switched in a variety of applications. Applications Information Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings, because stresses beyond the listed ratings can cause permanent damage to the devices. Always sequence V+ on first, followed by NO_, NC_, or COM_. Although it is not required, power-supply bypassing improves noise margin and prevents switching noise propagation from the V+ supply to other components. A 0.1F capacitor, connected from V+ to GND, is adequate for most applications. Analog Switch 2 Normally Closed Analog Switch 2 Common Analog Signal Levels Analog signals that range over the entire supply voltage (V+ to GND) can be passed with very little change in onresistance (see Typical Operating Characteristics). The switches are bidirectional, so the NO_, NC_, and COM_ pins can be used as either inputs or outputs. Layout High-speed switches require proper layout and design procedures for optimum performance. Reduce stray inductance and capacitance by keeping traces short and wide. Ensure that bypass capacitors are as close to the device as possible. Use large ground planes where possible. Logic Inputs The MAX4741/MAX4742/MAX4743 logic inputs can be driven up to +3.6V regardless of the supply voltage. For example, with a +1.8V supply, IN_ may be driven low to GND and high to +3.6V. Driving IN_ rail-to-rail minimizes power consumption. _______________________________________________________________________________________ 7 MAX4741/MAX4742/MAX4743 Pin Description 0.8, Low-Voltage, Single-Supply Dual SPST Analog Switches MAX4741/MAX4742/MAX4743 Test Circuits/Timing Diagrams V+ OPEN V+ NO_ NO_ VNO_ IN_ 50% VNO_ VCOM_ COM_ 90% VCOM_ 50 50% 0 MAX4741 IN_ tR < 5ns tF < 5ns VIH + 0.5V 50 GND 90% 0 35pF tON tOFF V+ OPEN V+ NC_ NC_ VIH + 0.5V VNC_ IN_ MAX4742 IN_ VCOM_ COM_ 50 50% 50% 0 50 GND 35pF VNC_ VCOM_ 0 90% tOFF 90% tON V+ VS V+ NC_ NO_ VIH + 0.5V VS IN_ 0 MAX4743 IN_ 50 GND VS VCOM_ COM_ 50 35pF 90% 90% VCOM_ 0 tBBM tBBM = tON(NO_) - tOFF(NC_) OR tBBM = tON(NC_) - tOFF(NO_) Figure 1.
