MAX4674

19-1708; Rev 2; 5/02 3V/5V, 4Ω, Wideband Quad 2:1 Analog Multiplexer General Description The MAX4674 is a low-voltage CMOS analog switch containing four 2:1 multiplexers/demultiplexer. When powered from a single +5V supply, it features a low 4Ω max on-resistance (RON), 0.4Ω max RON matching between channels, and 0.8Ω RON flatness over the entire signal range. Off-leakage current is only 0.5nA max at +25°C. The MAX4674 features fast turn-on (tON) and turn-off (tOFF) times of 18ns and 6ns, respectively, and is available 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 compatibility with +5V operation. o Guaranteed On-Resistance 4Ω max (+5V Supply) 6Ω max (+3V Supply) o Guaranteed Match Between Channels 0.4Ω max o Guaranteed Flatness Over Signal Range 0.8Ω max o 1.8V Operation RON = 100Ω typ Over Temperature tON = 51ns typ tOFF = 13ns typ o Guaranteed Low Leakage Currents 0.5nA max at +25°C o Single-Supply Operation from +1.8V to +5.5V o Rail-to-Rail® Signal Handling o TTL/CMOS-Logic Compatible o Crosstalk: -114dB (1MHz) o Off-Isolation: -67dB (1MHz) o 4mm ✕ 4mm QFN Package Features MAX4674 ________________________Applications 10/100 Base-T ATM Switching Audio and Video Signal Routing Low-Voltage Data-Acquisition Systems Communications Circuits Relay Replacement Ordering Information PART MAX4674EEE MAX4674EUE MAX4674ESE MAX4674EGE...
