45鈩? SPDT Analog Switch in SOT23-8
General Description
The MAX4649 is a dual-supply, single-pole/double-
throw (SPDT) analog switch. On-resistance is 45鈩?max
and flat (7鈩?max) over the specified signal range. The
MAX4649 can handle Rail-to-Rail
庐
analog signals, and
conducts analog or digital signals equally well in either
direction. This switch operates from a single +9V to
+36V supply, or from 卤4.5V to 卤20V dual supplies. The
primary application areas are in the switching and rout-
ing of signals in telecommunications and test equip-
ment.
The MAX4649 features a switch transition time of 130ns
max at +25掳C, and a guaranteed break-before-make
switching time of 5ns. Off-leakage current is only 2nA
max at +25掳C.
The MAX4649 is available in a tiny 8-pin SOT23 pack-
age.
