CMOS Analog Switches
General Description
The MAX4729/MAX4730 single-pole/double-throw
(SPDT) switches operate from a single supply ranging
from +1.8V to +5.5V. These switches provide low 3.5Ω
on-resistance (RON), as well as 0.45ΩRONflatness with
a +2.7V supply. These devices typically consume only
1nA of supply current, making them ideal for use in low-
power, portable applications. The MAX4729/MAX4730
feature low-leakage currents over the extended temper-
ature range, TTL/CMOS-compatible digital logic, and
excellent AC characteristics.
The MAX4729/MAX4730 are available in small 6-pin
SC70 and 6-pin µDFN packages. The MAX4729/
MAX4730 are offered in three pinout configurations to
ease design. The MAX4729/MAX4730 are specified
over the extended -40°C to +85°C temperature range.

Detailed Description
The MAX4729/MAX4730 single-pole/double-throw
(SPDT) switches operate from a single supply ranging
from +1.8V to +5.5V. These switches provide low 3.5Ω
on-resistance (RON), as well as 0.45ΩRONflatness with
a 2.7V supply. These devices typically consume only
1nA of supply current, making them suitable for use in
low-power, portable applications. The MAX4729/
MAX4730 feature low-leakage currents over the entire
temperature range, TTL/CMOS-compatible digital logic,
and excellent AC characteristics.
Applications Information
Digital Control Inputs
The MAX4729/MAX4730 logic inputs accept up to +5.5V,
regardless of supply voltage. For example, with a +3.3V
supply, IN can be driven low to GND and high to +5.5V,
allowing for mixing of logic levels in a system. With a 2.7V
to 3.6V power-supply voltage range, the logic thresholds
are set so VIL= 0.4V (max) and VIH= 2V (min).
Power-Supply Sequencing
and Overvoltage Protection
Caution:Do not exceed the absolute maximum ratings
because stresses beyond the listed ratings can cause
permanent damage to the device. Proper power-supply
sequencing is recommended for all CMOS devices.
Always apply V+ before applying analog signals, espe-
cially if the analog signal is not current limited.
