19-4729; Rev 3; 6/99 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 +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. ♦ 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 ______________Ordering Information PART TEMP.

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 +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.) 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.
