MPC507AU/1K - 8:1 Differential Analog Mux | Texas Instruments
N.º da peça: MPC507AU/1K ✗ Fim de vidaMPC507AU/1K Visão geral
An analog multiplexer is a switching IC that routes one of several input signals to a shared output while preserving the integrity of the selected waveform. A differential 8:1 mux combines that function with paired signal paths, allowing two related analog inputs to be selected together. In the electronics hierarchy, the MPC507 belongs to the analog switch and multiplexer class, then to interface ICs and semiconductors. This makes it useful where multiple sensors, measurement inputs, or control lines must share a limited number of converter and amplifier inputs.
The principal benefits of the MPC507AU/1K include protected analog inputs, a ±15 V signal range, dual 1.5 kOhm switch sections, and operating temperatures from -40°C to +85°C. The protection circuitry allows an analog input to exceed a supply voltage without damaging the device or disturbing other channels, according to the Texas Instruments MPC507 product information. This feature is valuable in industrial systems where transients or misconnection are possible.
Technically, the device uses CMOS analog switching to support the stated ±15 V range and sub-microsecond transitions. Break-before-make operation limits the interval in which old and new channels overlap, while true second-source behavior supports applications requiring duplicated paths. The 28-pin SOIC package is a surface-mount, gull-wing package suitable for conventional PCB assembly and automated production.
Typical applications include multiplexed data acquisition, industrial sensor routing, automated test equipment, analog signal instrumentation, and multi-channel measurement systems. In these systems, the MPC507 reduces the number of external analog front-end channels while preserving selectable overvoltage-protected inputs.
When designing around this multiplexer, verify the actual supply voltages, input range, channel timing, and leakage requirements against the manufacturer datasheet. Keep high-impedance routing short, provide adequate return paths, and account for source impedance when calculating settling behavior. The 1.5 kOhm maximum on-state resistance can create attenuation and channel-to-channel gain variation if the selected source impedance is high.

Aplicações típicas
MPC507AU/1K é adequado para 6 aplicaçãos: Industrial Sensor Multiplexing, Data-Acquisition Signal Routing, Automated Test Equipment, Analog Signal Conditioning, Communication Equipment Signal Routing, Medical and Diagnostic Instrumentation.
Industrial Sensor Multiplexing
The MPC507AU/1K fits industrial sensor-aggregation systems that must route several ±15 V differential signals into a shared analog front end. Its dual 8:1 architecture selects two related inputs together, while the verified 1.5 kOhm maximum on-state resistance is acceptable when the sensor and amplifier impedances are selected to control channel attenuation. Input-overvoltage protection is particularly useful where field wiring can introduce transients, because the manufacturer states that an overvoltage on one input does not disturb other channels. The 28-pin SOIC package simplifies conventional surface-mount assembly. Designers should still verify leakage, channel isolation, settling time, and the complete absolute-maximum ratings before applying the device to high-energy industrial nodes.
Recomendado
Data-Acquisition Signal Routing
The MPC507AU/1K can reduce the analog input count in a multiplexed data-acquisition system by selecting from eight differential channels through each of two switch sections. Its verified 200 ns turn-on and 250 ns turn-off times provide fast transitions, while the ±5 V to ±22 V dual-supply range supports bipolar acquisition nodes. The ±15 V analog signal capability is useful for instrumentation signals, but the 1.5 kOhm maximum on-state resistance creates a voltage-divider effect with the source and load impedances. A practical design should therefore include input buffering when source impedance is high, account for settling after each selection, and test crosstalk and channel-to-channel resistance matching over the intended temperature range.
Recomendado
Automated Test Equipment
The MPC507AU/1K is appropriate for automated test equipment that must connect multiple test points to a common measurement chain. Two 8:1 switch sections support paired routing, and the 28-pin SOIC footprint permits reuse of an existing multiplexer land pattern. Fast 200 ns turn-on and 250 ns turn-off characteristics help minimize dead time during test sequencing, although system-level settling can be much longer when driving high impedance. The verified input-overvoltage protection improves robustness when switching to imperfectly controlled external nodes. For production test fixtures, validate channel leakage, off-isolation, resistance matching, and the effect of fixture cables, because those system parasitics can dominate accuracy even when the IC itself meets its specified limits.
Recomendado
Analog Signal Conditioning
The MPC507AU/1K can route bipolar analog signals into a shared amplifier or converter in a signal-conditioning subsystem. Its ±15 V input range is larger than many common low-voltage sensor ranges, and dual supplies from ±5 V to ±22 V provide flexibility for bipolar laboratory and industrial circuits. The break-before-make characteristic helps prevent intentional overlap between the outgoing and incoming channels, while input-overvoltage protection reduces the chance that one abnormal signal will corrupt other paths. Engineers should design around the 1.5 kOhm maximum on-state resistance, adding a high-input-impedance buffer where attenuation from the switch resistance would reduce measurement accuracy. Protection energy, common-mode range, and supply sequencing also require verification for each source.
Recomendado
Communication Equipment Signal Routing
The MPC507AU/1K is usable in communication and network equipment when several externally routed analog lines must share a common receive or transmit path. The dual 8:1 organization allows paired channels to be selected simultaneously, and the 200 ns turn-on and 250 ns turn-off times support relatively quick routing changes. Its overvoltage protection can improve robustness in systems exposed to connected cables or imperfectly controlled external sources. The principal trade-off is the relatively high 1.5 kOhm maximum on-state resistance, which can attenuate high-impedance signals and introduce gain variation between channels. Use low-impedance drive paths or input buffers, maintain short routing to reduce pickup, and confirm off-isolation and crosstalk against the signal bandwidth required by the communication link.
Recomendado
Medical and Diagnostic Instrumentation
The MPC507AU/1K can support controlled analog routing in diagnostic and monitoring equipment where several bipolar inputs are multiplexed before amplification or conversion. The ±15 V signal range accommodates higher-level instrumentation signals, while the dual 8:1 structure reduces the number of front-end inputs required. Input-overvoltage protection may reduce system vulnerability to abnormal external conditions, although it is not a substitute for application-specific isolation, current limiting, or patient-protection networks. The 1.5 kOhm maximum on-state resistance must be considered in the complete input impedance and injected-current calculations. Medical designs should verify leakage, isolation, channel matching, and applicable product requirements against the manufacturer data sheet and the completed system rather than assuming general-purpose overvoltage protection establishes compliance.

Guia de seleção
Consider ADG507AKR when supply-chain goals favor a cross-brand source and the complete Analog Devices data sheet confirms matching pins, control levels, leakage, isolation, and timing. Do not choose it solely because it appears in a comparison result. For either device, add input buffering when source impedance is high, verify settling rather than relying only on 200 ns switch timing, and confirm absolute maximum ratings. This selection guidance favors the target where its documented protection, voltage range, and direct distributor sourcing reduce engineering uncertainty.

Notas de projeto
The verified maximum on-state resistance of 1.5 kOhm can create meaningful attenuation and channel-dependent gain error when connected to a high-impedance source or measurement input. Estimate the closed-loop division using the switch resistance, source impedance, and input impedance, then add a low-impedance buffer when the resulting error is not acceptable. Also evaluate leakage and capacitance at the selected signal bandwidth; the supplied data does not provide a complete leakage, isolation, or capacitance specification.
Keep each mux input and output trace short, provide a continuous ground reference, and place the device where field-wired inputs are protected and separated from sensitive circuitry. Because input overvoltage protection is a device feature rather than unlimited energy handling, use appropriate upstream attenuation or limiting for high-energy faults. The 28-pin SOIC package provides accessible gull-wing leads, but thermal performance and exposed-heat behavior still depend on the PCB copper and switching frequency.
Do not treat ±15 V as an unconditional absolute-maximum rating or assume that overvoltage protection permits unlimited fault energy. Verify the positive and negative supply limits, input limits, control-pin levels, and power-off behavior in the manufacturer data sheet. Also confirm that the selected replacement uses the same control logic and pin functions; the supplied web excerpt confirms a replacement relationship for ADG507AKR but does not provide every electrical comparison.
