MAX4644 Datasheet | Maxim Integrated

Description The MAX4644 is a single-pole/double-throw (SPDT) switch that operates from a single supply ranging from +1.8V to +5.5V. It provides low 4Ω on-resistance (RON) as well as 1Ω RON flatness over the entire analog signal range. The MAX4644 offers fast switching times of less than 20ns while ensuring break-before-make operation. It typically consumes only 0.01µW of quiescent power, making it suitable for use in low-power, portable applications. The MAX4644’s features include low leakage currents over the entire temperature range, TTL/CMOS-patible digital logic, and excellent AC characteristics. It is packaged in either a small 8-pin µMAX or a tiny 6-pin SOT23.
