DG408DY+T

P1-P3P4-P6P7-P9P10-P12
_______________General Description
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.
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.
