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) RON matching and 0.18Ω RON flatness. The digital logic input is 1.8V CMOS compatible when using a single +3V supply. The MAX4741EUA+T 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 MAX4741EUA+T 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.
