3V/5V, 4Ω, Wideband Quad 2:1 Analog Multiplexer
General Description Features
The MAX4674 is a low-voltage CMOS analog switch con- Guaranteed On-Resistance taining four 2:1 multiplexers/demultiplexer. When pow- 4Ω max (+5V Supply) ered from a single +5V supply, it features a low 4Ω max 6Ω max (+3V Supply) on-resistance (RON), 0.4Ω max RON matching between Guaranteed Match Between Channels channels, and 0.8Ω RON flatness over the entire signal 0.4Ω max range. Off-leakage current is only 0.5n A max at +25°C.
Guaranteed Flatness Over Signal Range
The MAX4674 features fast turn-on (t ON) and turn-off 0.8Ω max (t OFF) times of 18ns and 6ns, respectively, and is avail- 1.8V Operation able in QFN, QSOP, TSSOP, and SO packages. RON = 100Ω typ Over Temperature
This low-voltage multiplexer operates with a +1.8V to t ON = 51ns typ +5.5V single supply. All digital inputs have +0.8V and t OFF = 13ns typ
+2.4V logic thresholds, ensuring TTL/CMOS-logic com- Guaranteed Low Leakage Currents patibility with +5V operation. 0.5n A max at +25°C
Single-Supply Operation from +1.8V to +5.5V
