MAXIM MAX4674 Technical data

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 RONmatching 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 (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 com­patibility with +5V operation.

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.
