19-4729; Rev 6; 3/10 Improved, 16-Channel/Dual 8-Channel, CMOS Analog Multiplexers ____________________________Features Maxim’s redesigned DG406 and DG407 CMOS analog multiplexers now feature guaranteed matching between channels (8Ω, max) and flatness over the specified signal range (9Ω, max). These low on-resistance muxes (100Ω, 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 +85°C. The DG406 is a 1 of 16 multiplexer/demultiplexer and the DG407 is a dual 8-channel multiplexer/demultiplexer. Both muxes operate with a +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. ♦ Pin-Compatible Plug-In Upgrade for Industry Standard DG406/DG407 ♦ Guaranteed Matching Between Channels, 8Ω (max) ♦ Guaranteed On-Resistance Flatness, 9Ω (max) ♦ Guaranteed Low Charge Injection, 15pC (max) ♦ Low On-Resistance 100Ω (max) ♦ Input Leakage, 5nA (max) at +85°C ♦ Low Power Consumption, 1.25mW (max) ♦ Rail-to-Rail Signal Handling ♦ Digital Input Controls TTL/CMOS Compatible ♦ ESD Protection >2000V per Method 3015.7 ________________________Applications Sample-and-Hold Circuits Test Equipment Guidance and Control Systems Communications Systems Data-Acquisition Systems Audio Signal Routing _________________Pin Configurations Ordering Information PART DG406CJ+ DG406CWI+ DG406C/D DG406DJ+ DG406EWI+ DG406DN+ DG406AK+ DG406EUI+ TEMP RANGE PIN-PACKAGE 0°C to +70°C 0°C to +70°C 0°C to +70°C -40°C to +85°C -40°C to +85°C -40°C to +85°C -55°C to +125°C -40°C to +85°C 28 Plastic DIP 28 Wide SO Dice* 28 Plastic DIP 28 Wide SO 28 PLCC 28 CERDIP 28 TSSOP Ordering Information continued at end of data sheet. *Contact factory for dice specifications. +Denotes a lead(Pb)-free/RoHS-compliant package. _______________Functional Diagrams TOP VIEW + V+ 1 28 D N.C. 2 27 V- N.C. 3 26 S8 S16 4 25 S7 S15 5 S14 6 24 S6 DG406 23 S5 S13 7 22 S4 S12 8 21 S3 S11 9 20 S2 S10 10 19 S1 S9 11 18 EN GND 12 17 A0 N.C. 13 16 A1 A3 14 15 A2 V+ DIP/SO/TSSOP GND S1 S2 S3 S4 S5 S6 S7 S8 S9 S10 S11 S12 S13 S14 S15 S16 D CMOS DECODERS/DRIVERS A0 Pin Configurations continued at end of data sheet.

Not internally connected. Bidirectional Analog Inputs Ground Address Inputs Enable Input Bidirectional Analog Inputs 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. 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 +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.) V+ S D 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 6 Vg V- Figure 1.
