General Description
The MAX4641/MAX4642/MAX4643 are monolithic, dual,
single-pole/single-throw (SPST) switches that can operate
from a single supply ranging from +1.8V to +5.5V. The
MAX4641/MAX4642/MAX4643 provide low 4
on-resis-
tance (RON), 0.6
RON matching between channels, and
1
RON flatness over the entire analog signal range.
These devices offer fast switching times of less than 20ns
while consuming less than 0.01W of quiescent power.
The MAX4641 has two normally open (NO) switches,
and the MAX4642 has two normally closed (NC)
switches. The MAX4643 has one NO switch and one NC
switch. All three devices have low 0.35nA leakage cur-
rents over the entire temperature range. The MAX4641/
MAX4642/MAX4643 are available in small 8-pin MAX
and 8-pin QFN packages.
