Product details
Overview
M74HC4852RM13TR from STMicroelectronics is a dual 4:1 analog multiplexer/demultiplexer with injection current protection, designed for signal routing in mixed-signal systems. It features 150 Ω typical ON resistance at 6 V, 8.6 ns propagation delay at 4.5 V, and operates across 2–6 V supply. Its SO-16 package supports automotive (-55°C to +125°C) and industrial applications requiring robust analog channel isolation.
For engineers reviewing the M74HC4852RM13TR datasheet, M74HC4852RM13TR pinout, M74HC4852RM13TR application, or M74HC4852RM13TR equivalent, key selection criteria include ON resistance matching across channels, injection current immunity under overvoltage conditions, switching speed at target VCC, and compatibility with legacy 4052/4852 logic families.
Technical Context
The M74HC4852 implements two independent 4:1 analog switches controlled by shared A/B select lines and a global INH input. Each switch pair (X0–X3/Y0–Y3) routes signals bidirectionally between common terminals (XCOM/YCOM) and four channel I/Os, with latch-up immunity >500 mA per JESD17.
Its C2MOS silicon gate process enables low ICC (2 µA max at 25°C) and high noise immunity (28% VCC min), while the integrated injection current protection circuit limits output voltage shift to ≤1 mV when 1 mA is injected into disabled channels at VCC = 5 V with 3.9 kΩ series resistance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2 V to 6 V - supports single-supply operation across 3.3 V and 5 V logic domains without level shifting. |
| ON Resistance (Typ.) | 150 Ω at VCC = 6 V - ensures minimal signal attenuation and THD impact in audio and sensor front-end paths. |
| Propagation Delay (Typ.) | 8.6 ns at VCC = 4.5 V - enables sub-100 MHz analog switching in data acquisition and test equipment. |
| Injection Current Immunity | VΔOUT ≤ 1 mV at VCC = 5 V, IIN = 1 mA, RS = 3.9 kΩ - eliminates need for external clamping diodes in automotive battery-sensed circuits. |
| ESD Robustness | HBM: 2000 V, MM: 200 V, CDM: 1000 V - meets industrial handling requirements without additional ESD protection circuitry. |
| Operating Temperature | -55°C to +125°C - qualified for under-hood automotive and extended-range industrial control environments. |
Pinout & Package
Package: SO-16 (Small Outline, 16-pin, 3.9 mm body width, 1.27 mm pitch), ECOPACK® compliant, RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 11, 12, 14, 15 | X0–X3, Y0–Y3 | Independent analog I/O channels - eight bidirectional ports grouped as two sets of four, each routed to its COM terminal. |
| 3, 13 | XCOM, YCOM | Common analog terminals - serve as shared input/output nodes for respective X and Y switch banks. |
| 6 | INH | Global inhibit input - high-level assertion disables all switches, forcing high-impedance state on all channels. |
| 7 | NC | No connection - internally unconnected; must remain floating or grounded per layout best practice. |
| 9, 10 | A, B | Binary channel select inputs - define active channel index (0–3) for both X and Y banks simultaneously. |
| 8 | GND | Analog/digital ground reference - shared return path for supply and signal currents; requires low-impedance PCB connection. |
| 16 | VCC | Positive supply rail - powers internal logic and switch biasing; decoupling capacitor (100 nF) required within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Injection current protection | Output voltage shift ≤1 mV under 1 mA injected current - prevents crosstalk and signal corruption when disabled channels experience overvoltage transients. |
| Low ON-resistance mismatch | ΔRON ≤ 18 Ω max at 6 V - maintains amplitude and phase matching across channels in differential or multi-path signal routing. |
| Wide supply range support | Functional operation from 2 V to 6 V - allows direct interface with Li-ion battery systems (2.7–4.2 V), 3.3 V microcontrollers, and legacy 5 V peripherals. |
| High noise immunity | VNIH/VNIL ≥ 28% VCC - rejects fast transient coupling on select/control lines in electrically noisy engine control or motor drive environments. |
| Pin-compatible upgrade path | Direct replacement for CD4052B and M74HC4052 - enables drop-in migration to lower RON and improved injection tolerance without PCB redesign. |
Applications
| Automotive Sensor Multiplexing | Industrial Data Acquisition |
|---|---|
|
Use Scenario: Routing multiple thermistor, pressure, or position sensor outputs to a single ADC input in an engine control unit. IC Role / Device Role / Timing Role: Dual analog MUX providing isolated, low-distortion signal selection under wide temperature and voltage variation. Use Value: Injection current protection eliminates external diode networks needed to clamp sensor faults exceeding battery voltage, reducing BOM count and board area. |
Use Scenario: Scanning 8-channel analog inputs (e.g., RTDs, strain gauges) in a programmable logic controller (PLC) analog input module. IC Role / Device Role / Timing Role: Bidirectional analog switch enabling sequential sampling with <10 ns timing uncertainty between channels. Use Value: 150 Ω ON resistance at 6 V ensures <0.1% gain error across full-scale 0–10 V inputs when driving 10 kΩ ADC input impedance. |
| Consumer Audio Signal Routing | Test Equipment Channel Selection |
|
Use Scenario: Selecting between four microphone inputs or four line-level sources in a smart speaker or AV receiver. IC Role / Device Role / Timing Role: Low-noise analog MUX with <1 mV crosstalk under dynamic overvoltage - preserves SNR in AC-coupled audio paths. Use Value: 215 Ω typical RON at 3 V minimizes insertion loss in 3.3 V-powered portable audio subsystems without requiring gain compensation. |
Use Scenario: Configuring signal paths between DUT, stimulus source, and measurement instrument in automated test equipment (ATE). IC Role / Device Role / Timing Role: Fast-switching analog selector enabling <10 ns channel-to-channel transition for high-throughput parametric testing. Use Value: 8.6 ns tPD at 4.5 V allows stable settling before 100 MS/s sampling, supporting accurate characterization of RF and high-speed digital components. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 4:1 analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4052BE | Higher RON (1200 Ω typ. at 5 V), no injection current protection, slower tPD (>100 ns) | Limited to low-frequency (<10 kHz), low-voltage (<5 V) applications without overvoltage risk | Select only if cost sensitivity outweighs performance and robustness requirements; verify thermal derating above 70°C. |
| M74HC4052RM13TR | Same pinout but lacks injection current protection circuitry; RON = 170 Ω typ. at 6 V; identical temp range | Suitable where fault conditions are controlled and external clamping is acceptable | Prefer when system-level protection already exists and lowest possible RON is not critical; avoids premium for injection hardening. |
Compared with CD4052BE and M74HC4052RM13TR, the M74HC4852RM13TR delivers superior fault resilience and speed at modest RON trade-off, making it optimal for automotive and uncontrolled industrial signal routing where reliability trumps marginal cost savings.

FAQ
What is the maximum allowable voltage across the analog switch when enabled?
The M74HC4852 supports up to 1.2 V static or dynamic voltage across the switch (VI/O) when ON. Exceeding this may increase VCC current draw due to conduction through internal parasitic paths, though device reliability remains unaffected unless absolute maximum ratings (–0.5 V to VCC + 0.5 V) are violated.
Can the INH pin be left unconnected in normal operation?
No. The INH pin must be actively driven to logic low (≤0.5 V) to enable switching. Leaving it floating risks undefined behavior due to CMOS input sensitivity; tie to GND via 10 kΩ resistor if permanently enabled, or drive from MCU GPIO for dynamic control.
Is the M74HC4852RM13TR suitable for bidirectional analog signal routing?
Yes. All analog I/O pins (X0–X3, Y0–Y3, XCOM, YCOM) are fully bidirectional with symmetrical RON and capacitance. Signal flow direction is determined solely by external circuit topology, not internal architecture - confirmed by functional diagram and I/O equivalent circuit in datasheet Figure 3.
How does injection current protection function without external components?
The protection uses internal clamping structures that limit current flow from overvoltage-disabled channels into the substrate, preventing forward-biasing of parasitic junctions. This reduces output voltage perturbation on enabled channels to ≤1 mV, eliminating need for external Schottky diodes and series resistors typically used in legacy designs.
