Product details
Overview
MPC507APG4 from Texas Instruments is an 8-channel differential CMOS analog multiplexer with ±15V analog signal range, 1.5kΩ typical on-resistance, 70VPP analog overvoltage protection, break-before-make switching, and –40°C to +85°C operating temperature. It serves as a fault-tolerant signal routing device in industrial data acquisition systems interfacing external sensors with ±15V supplies.
For engineers reviewing the MPC507APG4 datasheet, MPC507APG4 pinout, MPC507APG4 application, or MPC507APG4 equivalent, key selection criteria include differential channel count, ±15V rail-to-rail analog handling, 70VPP overvoltage tolerance, 0.6µs maximum access time, and SOIC-28 package compatibility with legacy test equipment designs.
Technical Context
The MPC507APG4 implements dielectrically isolated CMOS switch architecture with integrated overvoltage clamps that isolate faulted inputs without disturbing active channels. Its 3-bit address decoder (A0–A2) and enable-controlled differential pair selection (Out A/Out B) support precise channel routing under ±15V dual-supply operation.
Break-before-make timing (25–80ns) prevents momentary shorting between differential pairs during switching, while 5pF channel output capacitance and 0.1pF input-to-output capacitance minimize crosstalk in high-impedance sensor interfaces. The device maintains <10nA off-state leakage across full temperature range and supports TTL-compatible digital control with 0.8V/4.0V logic thresholds.
Key Specifications

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG507AKRZ | ±15V rating, 400Ω RON, no overvoltage protection, SOIC-28 | Better on-resistance but lacks 70VPP fault tolerance; requires external clamping | Select when lowest RON dominates over fault resilience |
| MPC507AU | Identical electrical specs, same SOIC-28 package, RoHS-compliant NiPdAu finish | Same pinout and functionality; differs only in tape-and-reel packaging (1K vs 20-unit tube) | Choose MPC507APG4 for tube delivery; MPC507AU for reel-based SMT production |
Compared with ADG507AKRZ and MPC507AU, the MPC507APG4 uniquely combines 70VPP overvoltage immunity with industry-standard SOIC-28 footprint-enabling drop-in replacement in legacy designs where transient robustness is non-negotiable.

FAQ
What is the maximum analog input voltage the MPC507APG4 can withstand without damage?
The MPC507APG4 supports continuous analog input voltages up to ±20V beyond its ±15V supply rails and withstands 70VPP transient overvoltages. This is achieved via integrated overvoltage clamps that isolate faulted inputs without disrupting other channels or causing latch-up. Absolute maximum ratings specify ±33V analog overvoltage with 2µA off-leakage, confirmed in the SBFS018A datasheet Figure 8 curves.
Does the MPC507APG4 support single-ended signal routing?
No, the MPC507APG4 is exclusively an 8-channel differential analog multiplexer-each channel consists of matched A/B input pairs and corresponding A/B outputs. It does not support single-ended configurations. For single-ended applications, Texas Instruments specifies the MPC506A series (e.g., MPC506APG4), which provides 16 independent single-ended channels in the same SOIC-28 package.
What is the purpose of the VREF pin on the MPC507APG4?
The VREF pin (Pin 12) on the MPC507APG4 serves as a reference node for internal level-shifting circuitry used in digital input protection and decoder operation. Per the SBFS018A datasheet, VREF should be left open for standard TTL-compatible operation with 0.8V/4.0V logic thresholds. Connecting VREF to +10V enables MOS-drive mode with 6.0V logic-high threshold, but this configuration is rarely used in modern designs.
How does the MPC507APG4 handle power loss on one supply rail?
When either +VSUPPLY or –VSUPPLY fails, the MPC507APG4's dielectrically isolated CMOS process prevents latch-up and allows analog inputs to present a 1kΩ resistive path to ground-protecting external signal sources from short circuits. While signal feedthrough may occur during rail loss, the device remains undamaged and resumes normal operation upon supply restoration, as verified in the Absolute Maximum Ratings and Functional Description sections of SBFS018A.
Is the MPC507APG4 pin-compatible with earlier MPC507A variants?
Yes, the MPC507APG4 is fully pin-compatible and functionally identical to the original MPC507A and MPC507AU variants, sharing the same SOIC-28 (DW) package, pinout, electrical specifications, and thermal characteristics. The "PG4" suffix denotes Texas Instruments' standard tape-and-reel packaging variant with NiPdAu lead finish and MSL Level-2 rating-no circuit or layout changes are required for migration.
