General Description
MAX4644 General 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 4 on-resistance (RON) flatness over the entire analog signal as well as 1 RON range. The MAX4644 offers fast switching times of less than 20ns while ensuring break-before-make operation. It typically consumes only 0.01PAW of quiescent power making it suitable for use in low-power, portable applications.
The MAX4644's features include low leakage current over the entire temperature range, TTL/CMOS-compatible digital logic, and excellent AC characteristics. It is packaged in either a small 8-pin MAX or a tiny 6-pin SOT23.
