0.9, Low-Voltage, Single-Supply Quad SPST Analog Switches
General Description
The MAX4751/MAX4752/MAX4753 are low on-resistance, low-voltage, quad, 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 = 30ns, tOFF = 25ns), handle Rail-to-Rail(R) analog signals, and consume less than 1W of quiescent power. The MAX4753 has break-before-make switching. When powered from a +3V supply, the MAX4751/ MAX4752/MAX4753 feature low 0.9 (max) on-resistance (RON), with 0.12 (max) RON matching and 0.1 (max) RON flatness. The digital input is 1.8V CMOS compatible when using a single +3V supply. The MAX4751 has four normally open (NO) switches, the MAX4752 has four normally closed (NC) switches, and the MAX4753 has two NO and two NC switches. The MAX4751/MAX4752/MAX4753 are available in 3mm 3mm, 16-pin QFN and 14-pin TSSOP packages.

The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column. Parts are tested at +85C and guaranteed by design and correlation over the full temperature range. RON and RON matching specifications for QFN-packaged parts are guaranteed by design. RON = RON(MAX) - RON(MIN) Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog signal ranges. Note 7: Leakage parameters are 100% tested at the maximum-rated hot operating temperature and guaranteed by correlation at TA = +25C. Note 8: Guaranteed by design, not production tested.

0.9, Low-Voltage, Single-Supply Quad SPST Analog Switches
Detailed Description
The MAX4751/MAX4752/MAX4753 are low 0.9 max (at V+ = 3V) on-resistance, low-voltage quad analog switches that operate from a +1.6V to +3.6V single supply. CMOS construction allows switching analog signals that are within the supply voltage range (GND to V+). When powered from a +3V supply, the 0.9 (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_. If power-supply sequencing is not possible, add two small-signal diodes (D1, D2) in series with the supply pins for overvoltage protection (Figure 5). Adding these diodes reduces the analog signal by one diode drop below V+ and one diode drop above GND, but does not affect the low switch resistance and low leakage characteristics of the device. Device operation is unchanged, and the difference between V+ and GND should not exceed 4V. Power-supply bypassing is needed to improve noise margin and to prevent switching noise propagation from the V+ supply to other components. A 0.1F capacitor, connected from V+ to GND, is adequate for most applications.

resistance (see the 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 MAX4751/MAX4752/MAX4753 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.
Chip Information
TRANSISTOR COUNT: 228 PROCESS: CMOS
Analog Signal Levels
Analog signals that range over the entire supply voltage (V+ to GND) can be passed with very little change in on-
