Precision, 4-Channel/Dual 2-Channel, Low-Voltage, CMOS Analog Multiplexers
________________General Description
The MAX4518/MAX4519 precision, monolithic, CMOS analog multiplexers (muxes) offer low on-resistance (less than 100), which is matched to within 4 between channels and remains flat over the specified analog signal range (10 max). They also offer low leakage over temperature (NO-off leakage current less than 2nA at +85C) and fast switching speeds (transition time less than 250ns). The MAX4518 is a 4-channel device, and the MAX4519 is a dual 2-channel device. The MAX4518/MAX4519 are fabricated with Maxim's low-voltage silicon-gate process. Design improvements yield extremely low charge injection (less than 5pC) and guarantee electrostatic discharge protection greater than 2000V. These muxes operate with a single +2.7V to +15V supply or with bipolar 2.7V to 8V supplies, while retaining CMOS-logic input compatibility and fast switching. CMOS inputs provide reduced input loading.

Note 1: Signals on any terminal exceeding V+ or V- are clamped by internal diodes. Limit forward current to maximum current ratings.
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: 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: RON = RON(max) - RON(min). Note 5: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the specified analog signal ranges; i.e., VNO = 3V to 0V and 0V to -3V. Note 6: Leakage parameters are 100% tested at maximum rated hot operating temperature, and guaranteed by correlation at +25C. Note 7: Worst-case isolation is on channel 4 because of its proximity to the COM pin. Off isolation = 20log VCOM/VNO, VCOM = output, VNO = input to off switch. Note 8: Leakage testing at single supply is guaranteed by correlation testing with dual supplies.

__________Applications Information
Operation with Supply Voltages Other than 5V
Using supply voltages less than 5V reduces the analog signal range. The MAX4518/MAX4519 muxes operate with 2.7V to 8V bipolar supplies or with a +2.7V to +15V single supply. Connect V- to GND when operating with a single supply. Both device types can also operate with unbalanced supplies, such as +10V and -5V. The Typical Operating Characteristics graphs show typical on-resistance with 3V, 5V, +3V and +5V supplies. (Switching times increase by a factor of two or more for operation at 5V.)

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 can cause permanent damage to the devices. Always sequence V+ on first, then V-, followed by the logic inputs, NO, or COM. If power-supply sequencing is not possible, add two small signal diodes (D1, D2) in series with supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog signal range to one diode drop below V+ and one diode drop
-5V * INTERNAL PROTECTION DIODES
Figure 1. Overvoltage Protection Using External Blocking Diodes
above V-, but does not affect the devices' low switch resistance and low leakage characteristics. Device operation is unchanged, and the difference between V+ and V- should not exceed 17V. These protection diodes are not recommended when using a single supply.
