MAX4649 Datasheet, PDF (1/10 Pages) Maxim Integrated Products – 45Ω, SPDT Analog Switch in SOT23-8
19-1906; Rev 0; 2/01
45Ω, SPDT Analog Switch in SOT23-8
General Description
The MAX4649 is a dual-supply, single-pole/double-
throw (SPDT) analog switch. On-resistance is 45Ω max
and flat (7Ω max) over the specified signal range. The
MAX4649 can handle Rail-to-Rail® 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 ±4.5V to ±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°C, and a guaranteed break-before-make
switching time of 5ns. Off-leakage current is only 2nA
max at +25°C.
The MAX4649 is available in a tiny 8-pin SOT23 pack-
age.
