MAX4644 19-1657 Rev 1 1/11 High-Speed, Low-Voltage, 4, SPDT CMOS Analog Switch General Description Features The MAX4644 is a single-pole/double-throw (SPDT) +1.8V to +5.5V Single-Supply Operation switch that operates from a single supply ranging from Rail-to-Rail Analog-Signal Range +1.8V to +5.5V. It provides low 4 on-resistance (R ) ON Guaranteed R ON as well as 1 R flatness over the entire analog-signal ON 4 max (+5V Supply) range. The MAX4644 offers fast switching times of less 8 max (+3V Supply) than 20ns while ensuring break-before-make operation. +1.8V Operation It typically consumes only 0.01W of quiescent power, making it suitable for use in low-power, portable appli- R 30 (typ) Over Temperature ON cations. t 18ns (typ), t 12ns typ ON OFF Guaranteed R Flatness: 0.75 (typ) (+5V Supply) The MAX4644s features include low leakage currents ON over the entire temperature range, TTL/CMOS-compati- Guaranteed R Match Between Channels: ON ble digital logic, and excellent AC characteristics. It is 0.1 typ (+5V Supply) packaged in either a small 8-pin MAX or a tiny 6-pin Low Leakage (< 0.35nA) Over Entire Temperature SOT23.

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.
