19-6389; Rev 0; 6/12 MAX14589E/MAX14594E High-Density, ±5V Capable DPDT Analog Switches General Description Benefits and Features The MAX14589E/MAX14594E high-density, double-pole/ double-throw (DPDT) analog switches feature Beyondthe-Rails™ capability that allows signals from -5.5V to +5.5V to pass without distortion even when the power supply is below the signal range. The low RON resistance (0.2I) makes the devices ideal for low-distortion switching, such as audio. SDistortion-Free Beyond-the-Rails Signaling Negative Audio and Video Signal Capable -5.5V to +5.5V Analog Signal Range Independent from VCCEN On-Resistance 0.2I (typ) +1.6V to +5.5V Single-Supply Range Click-and-Pop Suppression The MAX14594E has internal shunt switches that discharge the audio amplifier AC-coupling capacitance at the normally open (NO1 and NO2) terminals. This feature reduces click-and-pop sounds that occur when switching audio signals between precharged points. SSmooth Switch Transition Break-Before-Make Operation The switches are fully specified to operate from a single +1.6V to +5.5V power supply. Because of the low supply current requirement, VCCEN can be provided by a GPIO. When the power is not applied, switches go to a highimpedance mode and all analog signal ports can withstand signals from -5.5V to +5.5V. The devices control the switches with a control bit, CB.

The MAX14589E/MAX14594E are low on-resistance and high ESD-protected DPDT switches that operate from a +1.6V to +5.5V supply and are designed to multiplex AC-coupled analog signals. These switches feature the low on-resistance (RON) necessary for highperformance switching applications. The Beyond-theRails signal capability of the analog channel allows signals below ground and above VCCEN to pass through without distortion. The shunt resistors are controlled by CB. When CB is low, NC_ is connected to COM_ and NO_ is connected to the shunt resistors. When CB is high, NO_ is connected to COM_ and the shunt resistors are unconnected. Analog Signal Levels The devices are bidirectional, allowing NO_, NC_, and COM_ to be configured as either inputs or outputs. The topology of the internal switches allows the signal to drop below ground without the need of an external negative voltage supply. Note: The devices can withstand analog signal levels of -5.5V to +5.5V when the device is not powered. Digital Control Input The devices provide a single-bit control logic input, CB. CB controls the switch position, as shown in the Typical Application Circuits/Functional Diagrams. Click-and-Pop Suppression (MAX14594E Only) The 500I shunt resistors automatically discharge any capacitance at both NO_ terminals when they are not connected to COM_. This reduces audio click-and-pop HIGHVOLTAGE DC SOURCE RC 1MΩ RD 1.5kΩ CHARGE-CURRENTLIMIT RESISTOR DISCHARGE RESISTANCE CS 100pF STORAGE CAPACITOR DEVICE UNDER TEST Applications Information Extended ESD Protection ESD-protection structures are incorporated on all pins to protect against electrostatic discharges up to ±2kV (HBM) encountered during handling and assembly. COM1 and COM2 are further protected against ESD up to ±15kV (HBM), ±10kV (Air-Gap Discharge), and ±8kV (Contact Discharge) without damage. NO_ and NC_ are further protected against ESD up to ±15kV (HBM) without damage. The ESD structures withstand high ESD both in normal operation and when the device is powered down. After an ESD event, the devices continue to function without latchup. ESD Test Conditions ESD performance depends on a variety of conditions. Contact Maxim for a reliability report that documents test methodology and test results. Human Body Model Figure 3 shows the Human Body Model. Figure 4 shows the current waveform it generates when discharged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest that is then discharged into the device through a 1.5kI resistor. IEC 61000-4-2 The IEC 61000-4-2 standard covers ESD testing and performance of finished equipment. It does not specifically refer to integrated circuits. The major difference between tests done using the HBM and IEC 61000-4-2 is higher peak current in IEC 61000-4-2, because series resistance is lower in the IEC 61000-4-2 model. Hence, the ESD withstand voltage measured to IEC 61000-4-2 is generally lower than that measured using the HBM. Figure 4 shows the IEC 61000-4-2 model and Figure 5 shows the current waveform for the ±8kV, IEC 61000-4-2, Level 4, ESD Contact-Discharge Method. Figure 3.
