The MAX4644 is a single-pole/double-throw (SPDT)
switch that operates from a single supply ranging from
+1.8V to +5.5V. It provides low 4Ω on-resistance (R
as well as 1Ω R
range. The MAX4644 offers fast switching times of less
than 20ns while ensuring break-before-make operation.
It typically consumes only 0.01μW of quiescent power,
making it suitable for use in low-power, portable appli-
cations.
The MAX4644’s features include low leakage currents
over the entire temperature range, TTL/CMOS-compati-
ble digital logic, and excellent AC characteristics. It is
packaged in either a small 8-pin μMAX
SOT23.
