Improved, 8-Channel/Dual 4-Channel,
CMOS Analog Multiplexers
_______________General Description
____________________________Features
Maxim’s redesigned DG408 and DG409 CMOS analog
multiplexers now feature guaranteed matching between
channels (8Ω max) and flatness over the specified sig-
nal 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.
ꢀ Pin-Compatible Plug-In Upgrades for
Industry Standard DG408/DG409
ꢀ 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
The DG408 is a 1-of-8 multiplexer/demultiplexer and
the DG409 is a dual 4-channel multiplexer/demultiplex-
er. Both muxes operate with a +4.5V to +30V single
supply and with 4.5V to ꢀ0V dual supplies. ꢁSD pro-
tection is guaranteed to be greater than ꢀ000V per
Method 3015.7 of MIL-STD-883. These improved
muxes are pin-compatible plug-in upgrades for the
industry standard DG408 and DG409.
ꢀ Low Power Consumption, 1.25mW Max
ꢀ Rail-to-Rail Signal Handling
ꢀ Digital Input Controls TTL/CMOS Compatible
ꢀ ESD Protection >2000V per Method 3015.7
