Product details
Overview
M74HCT4051RM13TR from STMicroelectronics is a single 8-channel analog multiplexer/demultiplexer with TTL-compatible digital control, ±6V analog input range, 70Ω typical on-resistance at 4.5V supply, 13ns typical propagation delay, and TSSOP-16 package. It enables bidirectional signal routing in mixed-signal systems where ±5V analog signals interface with 5V TTL logic.
For engineers reviewing the M74HCT4051RM13TR datasheet, M74HCT4051RM13TR pinout, M74HCT4051RM13TR application, or M74HCT4051RM13TR equivalent, key selection criteria include analog voltage range (±6V), on-resistance matching (≤180Ω max over temp), inhibit-controlled channel disable, and TSSOP-16 thermal performance for space-constrained PCB layouts.
Technical Context
The device integrates eight bidirectional analog switches with built-in level shifting to accept ±6V analog signals while operating from 0–6V digital control inputs. VEE pin supports negative rail connection for true bipolar analog operation, and INH input disables all channels simultaneously with TTL-level compatibility.
Its C2MOS silicon gate process delivers low quiescent current (4µA typ. at 25°C) and low distortion (0.02% THD at 9V supply), with AC performance validated at 120MHz bandwidth (common-to-switch path) and −50dB feedthrough attenuation at 1MHz when switched off.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range (VCC–VEE) | 2V to 12V - supports dual-rail analog operation down to ±1V or single-supply up to 12V headroom |
| On-Resistance (RON) | 70Ω typ. @ 4.5V/0V; 50Ω typ. @ 9V - ensures minimal analog signal attenuation and channel-to-channel matching ≤45Ω |
| Propagation Delay (tpd) | 13ns typ. @ 25°C - enables fast switching in data acquisition and sample-and-hold timing paths |
| Analog Input Range | ±6V peak - allows direct interfacing with industrial sensors, audio line-level signals, and op-amp outputs |
| Logic Compatibility | VIH = 2.0V min., VIL = 0.8V max. - fully interoperable with standard 5V TTL and HCT-series logic families |
| Quiescent Current (ICC) | 4µA max. @ 25°C - reduces system power budget in battery-operated or always-on monitoring circuits |
| THD @ 1kHz | 0.02% typ. @ 9V supply - preserves signal fidelity in precision instrumentation and audio routing |
Pinout & Package
TSSOP-16 package: 4.9 × 6.4 mm body, 0.65 mm pitch, 1.2 mm height, lead-free, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–4, 12–15 | Channel Inputs/Outputs (0–7) | Bidirectional analog terminals; each connects to COM when selected; supports ±6V swing |
| 3 | COM (Common I/O) | Shared analog path for all 8 channels; must be routed with controlled impedance for high-frequency signals |
| 6 | INH (Inhibit) | Active-high TTL-compatible enable/disable control; pulls all switches open when high |
| 7 | VEE | Negative supply rail for analog section; sets lower bound of analog input range (e.g., –6V when VCC = 0V) |
| 8 | GND | Digital ground reference; separate from analog return unless system design mandates single-point tie |
| 9–11 | A, B, C (Select Inputs) | 3-bit binary address for channel selection; TTL-compatible thresholds ensure robust noise margin |
| 16 | VCC | Positive supply for digital control logic and switch biasing; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Level-shifted digital control | Accepts 0–6V logic inputs while routing ±6V analog signals - eliminates external level translators |
| Low crosstalk (−50dB) | Minimizes signal coupling between unselected channels - critical for multi-channel sensor multiplexing |
| Fast enable/disable (11–68ns) | Reduces channel settling time during dynamic reconfiguration - improves throughput in scanning ADC systems |
| ESD-protected I/O | Integrated protection against ±20mA diode current - enhances reliability in handling and board-level ESD events |
| Wide bandwidth (120MHz) | Supports RF sampling, video switching, and high-speed test equipment signal routing without roll-off |

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 (120Ω typ. @ 4.5V), no VEE pin - requires GND-referenced analog signals only | Limited to unipolar 0–VCC analog ranges; unsuitable for ±6V or true bipolar sensor interfaces | Select when cost sensitivity outweighs bipolar range need and layout allows GND-referenced analog domain |
| ADG1408YRUZ | Lower RON (4.7Ω typ.), ±15V analog range, but requires ±15V supplies and SPI control instead of parallel address lines | Requires external level shifters for TTL control; better for high-precision, low-leakage metrology vs. general-purpose routing | Choose for sub-1Ω RON matching and ultra-low leakage (<1pA), accepting added supply complexity and serial interface overhead |
Compared with CD74HC4051M96 and ADG1408YRUZ, the M74HCT4051RM13TR uniquely balances TTL compatibility, ±6V analog range, and TSSOP-16 footprint-making it optimal for industrial PLCs and portable DAQ where dual-rail analog routing and minimal BOM count are prioritized.

FAQ
Can M74HCT4051RM13TR operate with VCC = 3.3V and VEE = –3.3V?
No. The device requires VCC – VEE ≥ 2V and VCC ≤ 5.5V per recommended conditions. At VCC = 3.3V, VEE must be ≥ –2.2V (e.g., –2V) to maintain 5.3V total supply. Operation at ±3.3V violates absolute maximum rating (VCC – VEE ≤ 13V is allowed, but VCC must not exceed 5.5V). Use only within 4.5–5.5V VCC and –6V to 0V VEE.
What is the maximum continuous current through a single channel?
The absolute maximum switch-through current (IT) is ±25mA. For reliable operation, limit steady-state current to ≤20mA per channel to avoid exceeding RON thermal drift and maintain distortion specs. Exceeding this risks parametric shift above 85°C ambient.
Does the INH pin require a pull-down resistor in normal operation?
No. INH has internal TTL-compatible input structure with defined VIH/VIL thresholds. When driven actively low by a microcontroller GPIO or logic gate, no external pull-down is needed. However, if left floating during power-up, an external 10kΩ pull-down is recommended to prevent undefined channel states.
How does crosstalk performance change with frequency?
Crosstalk between switches remains ≤−50dB up to 1MHz (sine wave test); above 1MHz, capacitive coupling increases, degrading isolation. For >10MHz signals, layout separation and guard traces around COM and channel pins are essential to maintain measured −50dB performance.
