Quad, SPST Analog Switch
________________General Description
The MAX4613 quad analog switch features on-resistance matching (4 max) between switches and guarantees on-resistance flatness over the signal range (9 max). This low on-resistance switch conducts equally well in either direction. It guarantees low charge injection (10pC max), low power consumption (35W max), and an electrostatic discharge (ESD) tolerance of 2000V minimum per Method 3015.7. The new design offers lower off leakage current over temperature (less than 5nA at +85C). The MAX4613 quad, single-pole/single-throw (SPST) analog switch has two normally closed switches and the two normally open switches. Switching times are less than 250ns for tON and less than 70ns for tOFF. Operation is from a single +4.5V to +40V supply or bipolar 4.5V to 20V supplies.

Note 1: Signals on S_, D_, or IN_ exceeding V+ or V- are clamped by internal diodes. Limit forward current to maximum current rating.
Stresses beyond those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Note 2: Typical values are for design aid only, are not guaranteed and are not subject to production testing. The algebraic convention, where the most negative value is a minimum and the most positive value a maximum, is used in this data sheet. Note 3: Guaranteed by design. Note 4: On-resistance match between channels and flatness are guaranteed only with bipolar-supply operation. Flatness is defined as the difference between the maximum and the minimum value of on-resistance as measured at the extremes of the specified analog signal range. Note 5: Leakage parameters IS(OFF), ID(OFF), ID(ON), and IS(ON) are 100% tested at the maximum rated hot temperature and guaranteed at +25C. Note 6: Off-Isolation Rejection Ratio = 20log (VD/VS). Note 7: Between any two switches.

___________Applications Information
General Operation
1) Switches are open when power is off. 2) IN_, D_, and S_ should not exceed V+ or V-, even with the power off. 3) Switch leakage is from each analog switch terminal to V+ or V-, not to other switch terminals.
Operation with Supply Voltages Other than 15V
Using supply voltages less than 15V will reduce the analog signal range. The MAX4613 operates with 4.5V to 20V bipolar supplies or with a +4.5V to +40V single

supply; connect V- to GND when operating with a single supply. Also, all device types can operate with unbalanced supplies such as +24V and -5V. VL must be connected to +5V to be TTL compatible, or to V+ for CMOS-logic level inputs. The Typical Operating Characteristics graphs show typical on-resistance with 20V, 15V, 10V, and 5V supplies. (Switching times increase by a factor of two or more for operation at 5V.)
V+
Overvoltage Protection
Proper power-supply sequencing is recommended for all CMOS devices. Do not exceed the absolute maximum ratings because stresses beyond the listed ratings may cause permanent damage to the devices. Always sequence V+ on first, followed by VL, V-, and logic inputs. If power-supply sequencing is not possible, add two small, external signal diodes in series with supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog signal range to 1V below V+ and 1V above V-, but low switch resistance and low leakage characteristics are unaffected. Device operation is unchanged, and the difference between V+ and Vshould not exceed +44V.
