SWITCHES SHOWN FOR A “1” INPUT LOGIC
GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The ADG733 and ADG734 are low voltage, CMOS devices
comprising three independently selectable SPDT (single pole,
double throw) switches and four independently selectable SPDT
switches respectively.
1. Single/Dual Supply Operation. The ADG733 and ADG734 are
fully specified and guaranteed with 3 V and 5 V single supply
rails and ± 3 V dual supply rails.
Low power consumption and operating supply range of 1.8 V to
5.5 V and dual ± 3 V make the ADG733 and ADG734 ideal for
battery powered, portable instruments. All channels exhibit
break-before-make switching action preventing momentary
shorting when switching channels. An EN input on the ADG733
is used to enable or disable the device. When disabled, all channels are switched OFF.
3. Low Power Consumption (<0.01 µW).
2. Low On Resistance (2.5 Ω typical).
4. Guaranteed Break-Before-Make Switching Action.
These 2–1 multiplexers/SPDT switches are designed on an
enhanced submicron process that provides low power dissipation
yet gives high switching speed, very low on resistance, high signal
bandwidths and low leakage currents. On resistance is in the region
of a few ohms, is closely matched between switches and very flat
over the full signal range. These parts can operate equally well
in either direction and have an input signal range which extends
to the supplies.
The ADG733 is available in small TSSOP and QSOP packages,
while the ADG734 is available in a small TSSOP package.

NOTES
1
Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; 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 IN, S or D will be clamped by internal diodes. Current should be
limited to the maximum ratings given.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADG733/ADG734 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high-energy electrostatic discharges. Therefore, proper
ESD precautions are recommended to avoid performance degradation or loss of functionality.
