MAX4641/MAX4642/MAX4643 19-1656 Rev 1 2/02 High-Speed, Low-Voltage, 4 , Dual SPST CMOS Analog Switches General Description Features The MAX4641/MAX4642/MAX4643 are monolithic, dual, +1.8V to +5.5V Single-Supply Operation single-pole/single-throw (SPST) switches that can operate Rail-to-Rail Analog Signal Range from a single supply ranging from +1.8V to +5.5V. The Guaranteed R ON MAX4641/MAX4642/MAX4643 provide low 4 on-resis- 4 max (+5V supply) tance (R ), 0.6 R matching between channels, and 8 max (+3V supply) ON ON 1 R flatness over the entire analog signal range. +1.8V Operation ON These devices offer fast switching times of less than 20ns R 30 typ Over Temperature ON while consuming less than 0.01W of quiescent power. t 18ns typ, t 12ns typ ON OFF Guaranteed R Flatness: 1 (+5V supply) ON The MAX4641 has two normally open (NO) switches, Guaranteed R Match Between Channels ON and the MAX4642 has two normally closed (NC) 0.6 (+5V supply) switches. The MAX4643 has one NO switch and one NC Low Leakage (<0.35nA) Over Entire Temperature switch. All three devices have low 0.35nA leakage cur- Range rents over the entire temperature 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.
