... It provides low 4Ω on-resistance (R as well as 1Ω R flatness over the entire analog-signal ON 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 appli- cations. The MAX4644’ ...

... Peak Current (NO, NC, and COM, pulsed at 1ms, 10% duty cycle)......................................................... ±100mA Note 1: Signals on NO, NC, COM exceeding V+ or GND are clamped by internal diodes. 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 ...

... GND Figure 1. Overvoltage Protection Using External Blocking Diodes Applications Information The MAX4644 operates from a single supply ranging from +1.8V to +5.5V. The device is guaranteed to be functional over that supply range, but TTL/CMOS com- patibility is only valid for operation using a +5V supply. All voltage levels are referenced to GND. Positive and negative DC analog inputs or AC signals can be accommodated by shifting V+ and GND ...
