Improved, 8-Channel/Dual 4-Channel,
CMOS Analog Multiplexers
_______________General Description
Maxim’s redesigned DG408 and DG409 CMOS analog
www.DamctahSuhaletneipnt4leUel.xsneet(r8sΩnomwaxfe)aatunrde
guaranteed matching between
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.
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 +5V to +30V single sup-
ply and with ±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 stan-
dard DG408 and DG409.

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: ΔRON = 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 +25°C.
Note 6: Off isolation = 20log VD/VS, where VD = output and VS = input to off switch.
