General Description
The MAX4645/MAX4646 single-pole, single-throw (SPST)
analog switches feature a 2.5 typical on-resistance
(RON) from a +5V supply. RON is flat (0.4 max) over the
specified signal range. Each switch can handle Rail-to-
Rail analog signals. Off-leakage current is 0.25nA max at
+25°C. These analog switches are ideal in low-distortion
applications and are the preferred solution over mechani-
cal relays in automated test equipment or applications
where current switching is required. They have low power
requirements, require less board space, and are more
reliable than mechanical relays.
These switches operate from a +1.8V to +5V single sup-
ply, making them ideal for use in battery-powered applica-
tions. The MAX4645/MAX4646 have fast switching speeds
of 12ns turn-on time (tON) and 8ns turn-off time (tOFF).
The MAX4645 is a normally open (NO) switch, and the
MAX4646 is a normally closed (NC) switch. Both are
available in 5-pin SOT23, 6-pin SOT23, and 8-pin MAX
packages.
