MPC508AP Descripción general
An analog multiplexer is an analog switch that routes one of several input signals to a common output. The MPC508AP belongs to the analog switch and multiplexer hierarchy, which supports signal acquisition, test systems, instrumentation, data conversion, and channel selection. Its 8:1 configuration reduces the number of external connections required when multiple sensors or measurement channels must share one downstream converter.
The principal verified features include an 8-channel single-ended input arrangement, a ±15 V analog signal range, 70 Vpp input overvoltage protection, break-before-make switching, and typical standby power of 7.5 mW. The overvoltage-protection architecture allows analog inputs to exceed the supply rails without disturbing other channels, a useful property in systems where a fault or transients may occur on an external signal line. The DIP-16 package also supports through-hole prototyping and replacement in designs designed around the original footprint.
The MPC508AP is distinct from a digital multiplexer because its switch path is intended to preserve analog signal fidelity rather than implement logic-level selection. Its CMOS implementation, protected inputs, and multiple analog channels make it suitable for data-acquisition front ends, automated test equipment, instrumentation, and signal-routing systems. The exact dynamic resistance, channel capacitance, leakage, propagation delay, supply-current, and logic-threshold values are not present in the supplied verified data and must be confirmed from the manufacturer datasheet before final design release.
A typical circuit places the selected input at the multiplexer output and connects that output to an ADC, amplifier, or measurement instrument. The system should provide suitable supply rails, observe the control-signal sequencing requirements, and account for analog input limits and off-channel behavior. The DIP package is mechanically straightforward, but users should follow the manufacturer’s pin and layout guidance rather than infer connections from generic DIP conventions.
This product data combines the verified Texas Instruments product identity, distributor listing information, datasheet references, and application-oriented guidance. It intentionally distinguishes documented parameters from unavailable technical fields rather than estimating them, helping engineers evaluate the MPC508AP for new designs and replacement planning.

Aplicaciones típicas
MPC508AP es adecuado para 6 aplicacións: Multichannel Data Acquisition, Automated Test Equipment, Industrial Sensor Interface, Instrumentation Signal Conditioning, Legacy 16-Bit Control Systems, Analog Signal Routing.
Multichannel Data Acquisition
The MPC508AP fits a data-acquisition front end that must route one of eight single-ended analog inputs to a shared ADC or measurement channel. Its 8:1 architecture reduces wiring and converter count while preserving a straightforward analog signal path. The verified 70-Vpp input overvoltage capability can improve robustness when inputs originate from external equipment, although system designers must still control fault current and confirm settling behavior. The 1.5-kOhm dynamic-resistance figure should be checked against source impedance and acquisition timing.
Recomendado
Automated Test Equipment
MPC508AP is useful in automated test equipment where multiple test points must be selected without duplicating the front-end measurement chain. The eight single-ended inputs can be routed to one instrument channel, while 70-Vpp overvoltage protection helps isolate the selector from unexpected test-signal excursions. The device’s break-before-make behavior is important when adjacent channels carry different voltages. Instrument designers should verify control timing, leakage, settling, and the exact pin map against the Texas Instruments datasheet before production release.
Recomendado
Industrial Sensor Interface
The MPC508AP can select among multiple industrial sensor lines when the system uses a common amplifier or converter. Its ±15 V analog signal range accommodates many legacy industrial signals, and the protected-input architecture is attractive when sensor wiring can experience transients or fault voltages. The eight-channel single-ended format is suitable for multiplexed pressure, temperature, position, or level signals. Designers should add appropriate input conditioning and verify that 1.5-kOhm switch resistance does not degrade sensor accuracy or conversion speed.
Recomendado
Instrumentation Signal Conditioning
MPC508AP provides analog channel selection ahead of shared signal-conditioning circuitry in instrumentation systems. By presenting one of eight single-ended inputs to a common amplifier or ADC, it can simplify front-panel routing and reduce component count. The CMOS implementation and 70-Vpp protection are useful for laboratory systems where input sources may be operator-connected. The part should be paired with input attenuation, clamping, and settling analysis because the verified data does not specify all leakage, bandwidth, and transition-time values.
Recomendado
Legacy 16-Bit Control Systems
The MPC508AP is compatible with the type of through-hole, multi-channel analog interface commonly found in legacy industrial and educational control systems. Its 16-pin PDIP package supports conventional prototyping and repair, while the eight single-ended inputs provide channel selection for external sensors or test points. System integrators should account for the device’s reported 1.5-kOhm dynamic resistance and ensure that control logic meets the manufacturer’s voltage specifications. The DIP package also makes inspection and replacement easier in through-hole assemblies.
Recomendado
Analog Signal Routing
MPC508AP can serve as a general analog signal-routing element when one of several external sources must be selected for downstream processing. The 8:1 single-ended arrangement is useful for programmable instrumentation and test fixtures, while 70-Vpp overvoltage protection adds resilience to input faults. Break-before-make switching helps prevent unintended channel-to-channel connection during changes. Because the supplied data does not include complete on-resistance, capacitance, and timing curves, engineers should validate bandwidth and insertion-loss requirements experimentally before using it in precision signal paths.

Notas de diseño
Treat the MPC508AP as an analog switch, not as a digital multiplexer. The verified 1.5-kOhm dynamic resistance can create a source-load interaction with the selected sensor or ADC input, so calculate the resulting divider, settling time, and acquisition aperture before committing to the channel count. Keep the selected trace short, use a suitable return path, and place any input filtering close to the protected analog pins. Exact on-resistance, capacitance, and settling values are not supplied here, so obtain them from the manufacturer datasheet.
Do not substitute the 70-Vpp input-protection rating for a complete external fault-protection design. The manufacturer describes the internal protection as allowing inputs to exceed the supply rails while preserving other channels, but external wiring, source impedance, current limiting, and downstream clamp requirements still depend on the system. Confirm the control-pin levels and power sequencing in the official pinout. A generic DIP-16 drawing must not be used because channel-select and supply assignments are specific to this multiplexer.
For a new through-hole implementation, preserve the verified PDIP-16 footprint and follow the Texas Instruments package drawing exactly. Route analog inputs and the common output away from digital control traces, clocks, and switching-power nodes. Place any protection, filtering, or buffer components near the connector or selected channel rather than at the far side of the board. Because the supplied data does not include a complete pinout or recommended layout, consult the manufacturer datasheet before finalizing routing and grounding.
