MAX4674 19-1708 Rev 3 12/06 3V/5V, 4 , 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- 4 max (+5V Supply) ered from a single +5V supply, it features a low 4 max 6 max (+3V Supply) on-resistance (R ), 0.4 max R matching between ON ON Guaranteed Match Between Channels channels, and 0.8 RON flatness over the entire signal 0.4 max range. Off-leakage current is only 0.5nA max at +25C. Guaranteed Flatness Over Signal Range The MAX4674 features fast turn-on (t ) and turn-off 0.8 max ON (t ) times of 18ns and 6ns, respectively, and is avail- OFF 1.8V Operation able in QFN, QSOP, TSSOP, and SO packages. R = 100 typ Over Temperature ON t = 51ns typ This low-voltage multiplexer operates with a +1.8V to ON t = 13ns typ OFF +5.5V single supply. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring TTL/CMOS-logic com- Guaranteed Low Leakage Currents patibility with +5V operation. 0.5nA max at +25C Single-Supply Operation from +1.8V to +5.5V Applications Rail-to-Rail Signal Handling 10/100 Base-T TTL/CMOS-Logic Compatible ATM Switching Crosstalk: -114dB (1MHz) Off-Isolation: -67dB (1MHz) Audio and Video Signal Routing 4mm 4mm QFN Package Low-Voltage Data-Acquisition Systems Communications Circuits Ordering Information Relay Replacement T EM P PIN- PKG PAR T R A N G E PAC K A G E C O D E M AX46 74E E E - 40C to + 85 C 16 QSOP E 16-4 M AX 4674E U E - 40C to + 85 C 16 TSS O P U16 -2 S 16-2 M AX46 74E S E - 40C to + 85 C 16 N arr ow S O M AX 4674E GE - 40C to + 85 C 16 QFN- E P * G 1644-1 M AX 4674E GP - 40C to + 85 C 20 QFN- E P * G 2044-3 *EP = Exposed pad.

Limit forward-diode current to max- imum current rating. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
