Improved, 16-Channel/Dual 8-Channel, CMOS Analog Multiplexers
_______________General Description
Maxim's redesigned DG406 and DG407 CMOS analog multiplexers now feature guaranteed matching between channels (8 max) and flatness over the specified signal range (9 max). These low on-resistance muxes (100 max) conduct equally well in either direction and feature guaranteed low charge injection (15pC max). In addition, these new muxes offer low input off-leakage current over temperature--less than 5nA at +85C. The DG406 is a 1 of 16 multiplexer/demultiplexer and the DG407 is a dual 8-channel multiplexer/demultiplexer. Both muxes operate with a +4.5V to +30V single supply and with 4.5V to 20V dual supplies. ESD protection is guaranteed to be greater than 2000V per Method 3015.7 of MIL-STD 883. These improved muxes are pin-compatible plug-in upgrades for the industry standard DG406 and DG407.

Signals on S_, D_, A0, A1, A2, A3, or EN 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). On-resistance match between channels and flatness are guaranteed only with specified voltages. Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured at the extremes of the specified analog signal range. Note 5: Leakage parameters are 100% tested at the maximum rated hot temperature and guaranteed by correlation at +25C. Note 6: Off isolation = 20log VD/VS, where VD = output and VS = input to off switch.

__________Applications Information
Operation with Supply Voltages Other than 15V
Using supply voltages other than 15V reduces the analog signal range. The DG406/DG407 switches operate with 4.5V to 20V bipolar supplies or with a +4.5V to +30V single supply; connect V- to GND when operating with a single supply. Also, both device types can operate with unbalanced supplies such as +24V and -5V. 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.)
signal range to 1V above V+ and 1V below V-, but low switch resistance and low leakage characteristics are unaffected. Device operation is unchanged, and the difference between V+ and V- should not exceed +44V.

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, then V-, followed by the logic inputs and analog signals. If power-supply sequencing is not possible, add two small signal diodes in series with supply pins for overvoltage protection (Figure 1). Adding diodes reduces the analog
