MAX4741

0.8Ω, Low-Voltage, Single-Supply Dual SPST Analog Switches


Please check latest availability status for a specific part variant.

Description

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 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.
