_______________General Description
Maxim’s redesigned DG408 and DG409 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 DG408 is a 1-of-8 multiplexer/demultiplexer and the DG409 is a dual 4-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 DG408 and DG409.

__________Applications Information
Operation with
Supply Voltages Other than 15V
Using supply voltages less than ±15V reduces the ana­log signal range. The DG408/DG409 switches operate 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. Both device types can also 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.)
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, S or D. 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 signal range to 1V below V+ and 1V 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 +44V.
