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 (R
ON
), as well as 0.45Ω R
ON
flatness 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.

ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
