The MUX508 offers 8:1 single-ended channels, whereas the MUX509 offers differential 4:1 or dual 4:1 single-ended channels. The MUX508 and MUX509 work equally well with either dual supplies (±5 V to ±18 V) or a single supply (10 V to 36 V). They also perform well with symmetric supplies (such as VDD = 12 V, VSS = –12 V), and unsymmetric supplies (such as VDD = 12 V, VSS = –5 V). All digital inputs have TTL-logic compatible thresholds, ensuring both TTL and CMOS logic compatibility when operating in the valid supply voltage range. 1 • • • • • • • • • • • • Low On-Capacitance – MUX508: 9.4 pF – MUX509: 6.7 pF Low Input Leakage: 10 pA Low Charge Injection: 0.3 pC Rail-to-Rail Operation Wide Supply Range: ±5 V to ±18 V, 10 V to 36 V Low On-Resistance: 125 Ω Transition Time: 92 ns Break-Before-Make Switching Action EN Pin Connectable to VDD Logic Levels: 2 V to VDD Low Supply Current: 45 µA ESD Protection HBM: 2000 V Industry-Standard TSSOP and SOIC Packages The MUX508 and MUX509 have very low on and off leakage currents, allowing these multiplexers to switch signals from high input impedance sources with minimal error. A low supply current of 45 µA allows for use in portable applications.

These devices operate up to 36 V, and offer true rail-to-rail input and output. The on-capacitance of the MUX50x is very low. These features makes the MUX50x a precision, robust, high-performance analog multiplexer for high-voltage, industrial applications. 10.2 Typical Application Figure 42 shows a 16-bit, differential, four-channel, multiplexed, data-acquisition system. This example is typical in industrial applications that require low distortion and a high-voltage differential input. The circuit uses the ADS8864, a 16-bit, 400-kSPS successive-approximation-resistor (SAR) analog-to-digital converter (ADC), along with a precision, high-voltage, signal-conditioning front end, and a four-channel differential mux.

The guidelines provided in this section are also applicable to the SOIC MUX508ID and MUX509ID package variants as well. Some key considerations are: 1. Decouple the VDD and VSS pins with a 0.1-µF capacitor, placed as close to the pin as possible. Make sure that the capacitor voltage rating is sufficient for the VDD and VSS supplies. 2. Keep the input lines as small as possible. For the MUX509 differential signals, make sure the A inputs and B inputs are as symmetric as possible. 3. Use a solid ground plane to help distribute heat and reduce electromagnetic interference (EMI) noise pickup. 4. Do not run sensitive analog traces in parallel with digital traces. Avoid crossing digital and analog traces if possible and only make perpendicular crossings when necessary.

Texas Instruments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications. 13.7 Glossary SLYZ022 — TI Glossary.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability information and additional product content details. TBD: The Pb-Free/Green conversion plan has not been defined. Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes. Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above. Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight in homogeneous material) (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
