MAX4680/MAX4690/MAX4700 19-1513 Rev 0 7/99 1.25, Dual SPST, CMOS Analog Switches General Description Features The MAX4680/MAX4690/MAX4700 dual analog switches Low On-Resistance (1.25 max) feature low on-resistance of 1.25 max. On-resistance is Guaranteed R Match Between Channels ON matched between switches to 0.3 max and is flat (0.3 (0.3 max) max) over the specified signal range. Each switch can handle Rail-to-Rail analog signals. Off-leakage current is Guaranteed R Flatness Over Specified ON only 5nA max at +85C. These analog switches are ideal Signal Range (0.3 max) in low-distortion applications and are the preferred solu- Rail-to-Rail Signal Handling tion over mechanical relays in automatic test equipment or applications where current switching is required. They Guaranteed Break-Before-Make (MAX4700) have low power requirements, require less board space, and are more reliable than mechanical relays. +4.5V to +36V Single-Supply Operation 4.5V to 20V Dual-Supply Operation The MAX4680 has two NC (normally closed) switches, and the MAX4690 has two NO (normally open) switch- TTL/CMOS-Compatible Control Inputs es. The MAX4700 has one NC and one NO switch and >2kV ESD Protection per Method 3015.7 features guaranteed break-before-make switching. These devices operate from a +4.5V to +36V single supply or from 4.5V to 20V dual supplies. A separate Ordering Information logic supply pin guarantees TTL/CMOS-logic compati- bility while operating across the entire supply voltage PART TEMP. RANGE PIN-PACKAGE range.

Limit forward diode current to maximum 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.
