GENERAL DESCRIPTION
The ADG608 and ADG609 are monolithic CMOS analog mul-
tiplexers comprising eight single channels and four differential
channels respectively, fully specified for
5 V, +5 V and +3 V
power supplies. The ADG608 switches one of eight inputs to a
common output as determined by the 3-bit binary address lines
A0, A1 and A2. The ADG609 switches one of four differential
inputs to a common differential output as determined by the
2-bit binary address lines A0 and A1. An EN input on both de-
vices is used to enable or disable the device. When disabled, all
channels are switched OFF. All the address and enable inputs
are TTL compatible over the full specified operating tempera-
ture range, making the parts suitable for bus-controlled systems
such as data acquisition systems, process controls, avionics and
ATEs since the TTL compatible address inputs simplify the digital
interface design and reduce the board space requirements.
The ADG608/ADG609 are designed on an enhanced LC
2
MOS
process that provides low power dissipation yet gives high
switching speed and low on resistance. Each channel conducts
equally well in both directions when ON and has an input signal
range which extends to the supplies. In the OFF condition, sig-
nal levels up to the supplies are blocked. All channels exhibit
break-before-make switching action preventing momentary
shorting when switching channels. Inherent in the design is low
charge injection for minimum transients when switching the
digital inputs.
The ability to operate from single +3 V, +5 V or
5 V bipolar
supplies makes the ADG608 and ADG609 perfect for use in
battery operated instruments and with the new generation of
DACs and ADCs from Analog Devices. The use of 5 V sup-
plies and reduced operating currents gives much lower power
dissipation than devices operating from
15 V supplies.
PRODUCT HIGHLIGHTS
1. Extended Signal Range
The ADG608/ADG609 are fabricated on an enhanced
LC
2
MOS process giving an increased signal range which
extends to the supplies.
2. Low Power Dissipation
3. Low R
ON
4. Fast Switching Times
5. Break-Before-Make Switching
Switches are guaranteed break-before-make so that input
signals are protected against momentary shorting.
6. Single/Dual Supply Operation

NOTES
1
Stresses above those listed under "Absolute Maximum Ratings" may cause
permanent damage to the device. This is a stress rating only and functional
operation of the device at these or any other conditions above those listed in the
operational sections of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
Only one absolute maximum rating may be applied at any one time.
2
Overvoltages at A, S, D or EN will be clamped by internal diodes. Current should
be limited to the maximum ratings given.
