3V/5V, 4鈩? Wideband Quad
2:1 Analog Multiplexer
General Description
The MAX4674 is a low-voltage CMOS analog switch con-
taining four 2:1 multiplexers/demultiplexer. When pow-
ered from a single +5V supply, it features a low 4鈩?max
on-resistance (R
ON
), 0.4鈩?max R
ON
matching between
channels, and 0.8鈩?RON flatness over the entire signal
range. Off-leakage current is only 0.5nA max at +25擄C.
The MAX4674 features fast turn-on (t
ON
) and turn-off
(t
OFF
) times of 18ns and 6ns, respectively, and is avail-
able in QFN, QSOP, TSSOP, and SO packages.
This low-voltage multiplexer operates with a +1.8V to
+5.5V single supply. All digital inputs have +0.8V and
+2.4V logic thresholds, ensuring TTL/CMOS-logic com-
patibility with +5V operation.
