Product details
Overview
M74HC4051RM13TR from STMicroelectronics is a single 8-channel analog multiplexer/demultiplexer with bidirectional CMOS switches, logic-level translation (0–6 V digital control ↔ ±6 V analog signal), 70 Ω typical ON resistance at 4.5 V supply, and 15 ns typical propagation delay. It operates across 2–12 V supply range (VCC–VEE) and is used in precision analog signal routing for data acquisition systems.
For engineers reviewing the M74HC4051RM13TR datasheet, M74HC4051RM13TR pinout, M74HC4051RM13TR application, or M74HC4051RM13TR equivalent, key selection criteria include analog input voltage range (±6 V), ON resistance matching (ΔRON ≤ 15 Ω at 4.5 V/–4.5 V), inhibit-controlled channel disable, and SOP-16 package compatibility with PCB layout constraints.
Technical Context
The device implements eight digitally controlled analog switches using silicon gate C2MOS technology, with built-in level shifting to interface 5 V TTL/CMOS logic with ±6 V analog signals. The INH pin provides global channel disable, while A/B/C address inputs select one of eight bidirectional paths between COM and channels 0–7.
It supports dual-supply operation (VCC ≥ 2 V, VEE ≤ 0 V, VCC–VEE ≤ 12 V), enabling rail-to-rail analog signal handling. Switch characteristics are specified across –55 °C to +125 °C, with low crosstalk (–50 dB) and feedthrough attenuation (–50 dB), ensuring signal integrity in multi-channel analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channel count | 8 bidirectional analog switches with common terminal (COM) |
| ON resistance (RON) | 50 Ω typ at VCC=6 V, VEE=–6 V - enables low-loss signal routing in sensor interfaces |
| Analog input range | ±6 V peak - supports full-range bipolar signal conditioning without external level shifters |
| Propagation delay (tpd) | 13 ns typ at VCC=6 V - suitable for multiplexed ADC sampling up to ~30 MSPS effective rate |
| Supply range (VCC–VEE) | 2 V to 12 V - allows flexible biasing for mixed-signal systems with varying analog rails |
| Logic compatibility | 74-series 4051 pin/function compatible - simplifies legacy design upgrades and footprint reuse |
| Quiescent current (ICC) | 4 μA max at TA=25 °C - enables ultra-low-power operation in battery-backed data loggers |
Pinout & Package
SOP-16 surface-mount package (JEDEC MS-012AC, 3.9 mm × 9.9 mm body, 1.27 mm pitch), RoHS-compliant and ECOPACK® certified.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 3 (COM) | Common analog I/O terminal | Bidirectional path shared across all 8 channels; connects to ADC input or DAC output |
| 6 (INH) | Inhibit control input | High-level assertion disables all switches - critical for fault-safe signal isolation |
| 7 (VEE) | Negative analog supply | Establishes lower analog rail; required for ±6 V input range; tied to GND for unipolar use |
| 9–11 (A, B, C) | Binary channel select inputs | 3-bit address selects one of eight channels (0–7); TTL/CMOS compatible thresholds |
| 1–2, 4–5, 12–15 (0–7) | Independent analog I/O terminals | Each serves as source/sink for analog signals; matched RON ensures channel uniformity |
| 8 (GND) | Digital ground reference | Reference for control logic; separate from analog return paths in mixed-signal layouts |
| 16 (VCC) | Positive supply voltage | Powers internal logic and switch drivers; decoupling required within 1 cm of pin |
Key Features
| Feature | Design Value |
|---|---|
| Logic-level translation | Enables 0–6 V digital control signals to route ±6 V analog signals without external level shifters |
| Low ON-resistance mismatch | ΔRON ≤ 15 Ω (typ) at VCC=4.5 V/VEE=–4.5 V - preserves gain accuracy across channels in PGA designs |
| High noise immunity | VNIH/VNIL = 28 % VCC (min) - prevents false switching in electrically noisy industrial environments |
| Low distortion | 0.018 % THD+N at VCC=6 V/VEE=–6 V - maintains fidelity in audio and precision instrumentation paths |
| Fast enable/disable timing | tPZL/tPLZ = 15/28 ns (typ) at VCC=6 V - minimizes dead time during channel switching in real-time control loops |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD74HC4051M96 | Higher RON (80 Ω typ at 4.5 V), no VEE pin - requires unipolar analog signals only | Limited to 0–5 V analog ranges; unsuitable for bipolar sensor interfaces | Select when cost sensitivity outweighs need for ±6 V operation and board space permits external level shifters |
| ADG1408YRUZ | Lower RON (4.7 Ω typ), ±15 V rating, but 5 V-only logic interface and higher ICC (200 μA) | Requires level-shifter for MCU interfacing; better for high-precision, low-RON needs | Choose for medical-grade low-distortion (<0.001 %) and high-voltage (±15 V) applications where power budget allows |
Compared with CD74HC4051M96 and ADG1408YRUZ, the M74HC4051RM13TR uniquely balances ±6 V analog support, 50 Ω RON, and 4 μA quiescent current in SOP-16 - making it optimal for space-constrained, battery-powered industrial DAQ where bipolar signal integrity and low standby power are co-priorities.

FAQ
What is the maximum allowable analog signal voltage swing for M74HC4051RM13TR?
The device supports analog input voltages from VEE – 0.5 V to VCC + 0.5 V. With VCC = 6 V and VEE = –6 V, the absolute maximum analog swing is –6.5 V to +6.5 V peak. For reliable operation, ST specifies ±6 V peak as the functional range per Table 9, confirmed by sine wave distortion and bandwidth tests at those levels.
Can M74HC4051RM13TR operate with VEE tied to GND?
Yes - connecting VEE to GND configures the device for unipolar operation (0 V to VCC analog range). In this mode, the analog input range becomes 0 to VCC, and the level-shifting circuitry adapts accordingly. All DC and AC specifications in Tables 6–9 include GND-referenced VEE test conditions.
Is the INH pin active-high or active-low?
The INH pin is active-high: when INH = HIGH (≥ VIHC), all eight analog switches are turned OFF regardless of A/B/C address states. When INH = LOW (≤ VILC), channel selection proceeds normally. This behavior is explicitly defined in Table 3 (Truth table) and Figure 5 (Functional diagram).
Does M74HC4051RM13TR support hot insertion or live signal switching?
No - the device lacks explicit hot-swap protection. Switching while analog signals are present may cause transient currents exceeding ±25 mA (absolute max IT), risking latch-up or accelerated wear. ST recommends asserting INH before changing analog connections and verifying VI/O stays within VEE – 0.5 V to VCC + 0.5 V during transitions.
