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 (<100

Ω) 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.
