Single 8-Channel/Differential
4-Channel CMOS Analog Multiplexers
Description
The DG408/883 Single 8-Channel and DG409/883 Differen-
tial 4-Channel monolithic CMOS analog multiplexers are
drop-in replacements for the popular DG508A and DG509A
series devices. They each include an array of eight analog
switches, a TTL/CMOS compatible digital decode circuit for
channel selection, a voltage reference for logic thresholds
and an ENABLE input for device selection when several mul-
tiplexers are present.
The DG408/883 and DG409/883 feature lower signal ON
resistance (<100Ω) and faster switch transition time (t
TRANS
<250ns) compared to the DG508A or DG509A. Charge
injection has been reduced, simplifying sample and hold
applications. The improvements in the DG408/883 series are
made possible by using a high-voltage silicon-gate process.
An epitaxial layer prevents the latch-up associated with older
CMOS technologies. Power supplies may be single-ended
from +5V to +34V, or split from
±5V
to
±20V.
The analog switches are bilateral, equally matched for AC or
bidirectional signals. The ON resistance variation with ana-
log signals is quite low over a
±5V
analog input range.
