MAX4667/MAX4668/MAX4669 19-1505 Rev 0 7/99 2.5, Dual, SPST, CMOS Analog Switches General Description Features The MAX4667/MAX4668/MAX4669 dual analog switches Low On-Resistance (2.5 max) feature low on-resistance of 2.5 max. On-resistance is Guaranteed R Match Between Channels ON matched between switches to 0.5 max and is flat (0.5 (0.5 max) max) over the specified signal range. Each switch can handle Rail-to-Rail analog signals. The off-leakage cur- Guaranteed R Flatness over Specified Signal ON rent is only 5nA max at +85C. These analog switches Range (0.5 max) are ideal in low-distortion applications and are the pre- Guaranteed Break-Before-Make (MAX4669) ferred solution over mechanical relays in automatic test equipment or applications where current switching is Rail-to-Rail Signal Handling required. They have low power requirements, use less board space, and are more reliable than mechanical Guaranteed ESD Protection >2kV relays. per Method 3015.7 The MAX4667 has two normally closed (NC) switches, +4.5V to +36V Single-Supply Operation the MAX4668 has two normally open (NO) switches, 4.5V to 20V Dual-Supply Operation and the MAX4669 has one NC and one NO switch that TTL/CMOS-Compatible Control Inputs guarantee break-before-make operation. These switches operate from a +4.5V to +36V single supply or from 4.5V to 20V dual supplies. All digital inputs have +0.8V and +2.4V logic thresholds, ensuring Ordering Information TTL/CMOS-logic compatibility when using 15V sup- plies or a single +12V supply. PART TEMP.

Limit the 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.
