MPC507APG4 - 8-Channel Differential Analog Multiplexer | TI
부품 번호: MPC507APG4 ✓ 활성MPC507APG4 개요
An analog multiplexer is an interface IC that connects multiple analog inputs to a shared output under digital control. A differential multiplexer can route paired input signals and reduce common-mode interference, while a single-ended multiplexer selects one signal relative to ground. In the IC hierarchy, the MPC507APG4 is a CMOS analog switch, analog multiplexer, interface IC, and semiconductor designed to route instrumentation and control signals efficiently.
Key features include analog overvoltage protection, no channel interaction during overvoltage, and break-before-make switching. The supported analog signal range reaches ±15 V, while standby power is 7.5 mW typical. The MPC507A family provides 16 single-ended channels or eight differential channels, making it useful for multichannel measurement, test, instrumentation, and signal-routing systems.
The device uses separate digital address and enable controls to select one of eight differential channels. Because it is a CMOS implementation, low switching time and low standby power support acquisition systems that repeatedly change measurement paths. The dual-supply architecture also allows bipolar signals to be routed without a single-supply level-shifting arrangement.
Typical applications include automated test equipment, data-acquisition systems, process-control instrumentation, multiplexed sensor interfaces, and laboratory measurement systems. Engineers should account for the relatively high 1.5 kOhm on-state resistance when interpreting source impedance, and should verify that every selected input remains within the device's absolute maximum ratings.
Designers should preserve break-before-make timing and route sensitive analog inputs away from high-impedance control nets. Input filtering may be required when leakage, switching transients, or overvoltage events could affect the measured signal. The 28-pin PDIP also requires adequate spacing between adjacent boards and provides straightforward through-hole assembly for legacy and industrial equipment.
This page consolidates verified manufacturer and distributor details, compares directly related MPC507 variants, and adds practical guidance on switching, signal integrity, protection, and procurement for engineers evaluating this legacy analog multiplexer.

Automated Test Equipment
The MPC507APG4 is suitable for routing multiple test points to a shared measurement front end because it provides eight differential channels, break-before-make operation, and switching times of 200 ns Ton and 250 ns Toff. A test system can use the digital address and enable controls to connect one of eight paired inputs to downstream instrumentation without cross-connecting channels during a transition. The ±15 V analog signal range supports many externally generated test signals, while the overvoltage-protection feature adds resilience when a test node is unintentionally driven beyond the normal input level. Designers should still validate absolute maximum conditions, external source impedance, and the 1.5 kOhm maximum on-state resistance before assigning high-precision measurements to the selected channel.
추천
Data Acquisition Systems
The MPC507APG4 can concentrate eight differential measurement channels onto one shared analog path in a data-acquisition system. Differential operation helps preserve the relationship between paired sensor outputs and can reduce common-mode pickup, while the alternative single-ended configuration provides up to 16 addressed inputs. The 200 ns turn-on and 250 ns turn-off times allow the switching network to operate between successive acquisitions when the downstream amplifier and converter settling times are adequate. Break-before-make behavior prevents unintended channel overlap, and 7.5 mW typical standby power is useful in compact multi-channel systems. Practical designs should include settling time, leakage, source impedance, and the 1.5 kOhm maximum on-resistance in the error budget.
추천
Process-Control Instrumentation
The MPC507APG4 fits process-control systems that must sample several sensor or actuator lines using a shared measurement or drive circuit. Its dual +5 V to ±22 V supply capability and ±15 V analog range accommodate bipolar industrial signals, while eight differential channels reduce the number of wiring paths to the controller. The overvoltage-protection characteristic and absence of channel interaction during an overvoltage improve robustness when field wiring is exposed to transients or incorrect conditions. Break-before-make switching keeps adjacent channels isolated during address changes. Installation should still include appropriate external protection because the device's internal protection does not eliminate the need for surge, clamp, or fusing requirements imposed by the field wiring.
추천
Laboratory Measurement Systems
The MPC507APG4 can select among eight differential sources in a laboratory measurement system while preserving a controlled measurement sequence. Its 200 ns Ton and 250 ns Toff times provide fast path selection, and the break-before-make characteristic helps avoid accidental connection of two driven outputs. The ±15 V signal range is useful for bipolar sensor and instrumentation signals, and the 28-pin PDIP package is convenient for laboratory or legacy instrument construction. Because the maximum on-state resistance is 1.5 kOhm, high-impedance buffers may be required near sensitive sources. Designers should also account for channel leakage, switch-induced transients, and amplifier settling after every address change.

Multiplexed Sensor Interfaces
The MPC507APG4 is applicable to multichannel sensor front ends where several paired sensor outputs must be routed to one amplifier or converter. Differential channel support is useful for bridge, current, and instrumentation-style outputs because it carries both halves of each measurement together. The device's analog overvoltage protection and no-interaction behavior provide additional robustness during connection faults, while the 1.5 kOhm maximum on-state resistance must be included when calculating effective source impedance. For high-impedance sensors, add a suitable low-input-capacitance buffer and verify leakage against the required accuracy. The break-before-make transition also prevents two sensor channels from being unintentionally tied together during selection.
추천
Legacy Control Signal Routing
The MPC507APG4 can route low-frequency control and status signals in legacy industrial equipment that uses through-hole analog multiplexing. Sixteen single-ended channels or eight differential channels provide flexibility where one controller must monitor several command, feedback, or interlock lines. The dual-supply operation supports bipolar control voltages, and the 28-pin PDIP package is compatible with conventional through-hole assembly and repair practices. Break-before-make switching ensures that address transitions do not momentarily join two independently driven signals. Engineers should verify input overvoltage levels, supply tolerances, logic thresholds, and output capacitance for the specific controller. Where two controlled sources can differ substantially, include external isolation or protection rather than relying solely on internal overvoltage handling.

설계 노트
Include the selected switch's maximum 1.5 kOhm on-state resistance in the complete source-impedance calculation. For a high-impedance sensor, the switch resistance, amplifier bias current, leakage, and cable capacitance can dominate measurement error. Place a low-input-impedance buffer close to the MPC507APG4 when the connected source has high impedance, and verify that downstream settling is complete after the 200 ns Ton or 250 ns Toff interval.
Do not treat the overvoltage-protection feature as permission to apply arbitrary voltages. Check the manufacturer absolute maximum ratings, supply limits, and analog input conditions before energizing unused or externally connected channels. The normal specified analog signal range is ±15 V, and dual supplies may extend to ±22 V. Incorrect sequencing or exceeding the input limits can still damage the device or invalidate a measurement.
Place analog input and output routing away from digital address and enable traces to minimize switching crosstalk. Use a continuous ground plane, decouple each supply rail near the device, and route sensitive differential pairs together with consistent geometry. The through-hole 28-pin PDIP requires adequate board spacing and lead-bend clearance, particularly in densely populated legacy control systems.
Account for switch capacitance and downstream filter settling when switching rapidly between channels. If the measurement path includes a sampling switch or amplifier with a long time constant, add an acquisition delay after the address change. The break-before-make architecture prevents direct channel overlap, but it does not eliminate the transient caused by moving charge between the old and new path.
