MAXIM MAX4742EKA

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.
• Low RON: 0.8Ω max (+3V Supply), 2.5Ω max (+1.8V Supply)
• 0.18Ω max RON Flatness (+3V Supply)
• +1.6V to +3.6V Single-Supply Operation
• Available in SOT23 and μMAX Packages
• High-Current Handling Capacity (150mA continuous)
• 1.8V CMOS Logic Compatible (+3V Supply)
• Fast Switching: tON = 24ns, tOFF = 16ns
