general description the max14589e/max14594e high-density, double-pole/ double-throw (dpdt) analog switches feature beyond- the-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 r on resistance (0.2 i ) makes the devices ideal for low-distortion switch - ing, such as audio. 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. the switches are fully specified to operate from a single +1.6v to +5.5v power supply. because of the low supply current requirement, v ccen can be provided by a gpio. when the power is not applied, switches go to a high- impedance mode and all analog signal ports can with - stand signals from -5.5v to +5.5v. the devices control the switches with a control bit, cb. the max14589e/max14594e are available in a 1.2mm x 1.2mm, 0.4mm pitch, 9-bump wafer-level package (wlp), and operate over the -40 n c to +85 n c extended temperature range. applications smartphones tablets portable audio/video equipment portable navigation devices benefits and features s distortion-free beyond-the-rails signaling ? negative audio and video signal capable ? -5.5v to +5.5v analog signal range independent from v ccen ? on-resistance 0.2 i (typ) ? +1.6v to +5.5v single-supply range ? click-and-pop suppression s smooth switch transition ? break-before-make operation s low supply current 30a (typ) at 1.6v ? can be powered by a gpio ? high-impedance mode when v ccen not applied s esd protection on com_ ? 15kv human body model ? 10kv iec 61000-4-2 air gap ? 8kv iec 61000-4-2 contact s esd protection on nc_ and no_ ? 15kv human body model s small board space ? 9-bump wlp (1.2mm x 1.2mm) package s -40 n c to +85 n c operating temperature range 19-6389; rev 1; 1/13 ordering information/selector guide appears at end of data sheet. for related parts and recommended products to use with this part, refer to www.maximintegrated.co m/ max14589e.related . beyond-the-rails is a trademark of maxim integrated products, inc. max14589e/max14594e high-density, 5v capable dpdt analog switches for pricing, delivery, and ordering information, please contact maxim direct at 1-888-629-4642, or visit maxim integrateds website at www.maximintegrated.com.

9 detailed description 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 (r on ) necessary for high- performance switching applications. the beyond-the- rails signal capability of the analog channel allows signals below ground and above v ccen to pass through without distortion. 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 nega - tive 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 500 i shunt resistors automatically discharge any capacitance at both no_ terminals when they are not connected to com_. this reduces audio click-and-pop sounds that might occur when switching between capac - itively coupled audio sources. 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. 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 1.5k i resistor. iec 61000-4-2 the iec 61000-4-2 standard covers esd testing and performance of finished equipment. it does not spe - cifically 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. human body esd test model charge-current- limit resistor discharge resistance storage capacitor c s 100pf r c 1m r d 1.5k high- voltage dc source device under test max14589e/max14594e high-density, 5v capable dpdt analog switches maxim integrated
