Product details

Overview

74HC4051PW,112 from NXP Semiconductors is an 8-channel analog multiplexer/demultiplexer in TSSOP-16 package, operating from 2V to 10V supply, with on-resistance of 120 Ω at V_CC = 4.5V, and channel leakage current ≤100 nA at 25°C. It serves as a bidirectional signal routing switch in mixed-signal data acquisition systems.

For engineers reviewing the 74HC4051PW,112 datasheet, 74HC4051PW,112 pinout, 74HC4051PW,112 application, or 74HC4051PW,112 equivalent, key selection criteria include supply voltage range, on-resistance matching across channels, break-before-make timing, and ESD tolerance for sensor interface protection.

Technical Context

This CMOS device uses standard HC logic levels for control inputs (A0–A2, INH), enabling direct interfacing with microcontrollers and FPGAs. Its analog channel switching is symmetrical-supporting bidirectional signal flow up to ±5V peak-to-peak when V_CC = 10V and V_EE = 0V.

The enable (INH) input provides high-impedance state for all channels when asserted high, and propagation delay from address change to channel stabilization is typically 12 ns at V_CC = 4.5V, 25°C.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	2.0 V to 10.0 V - supports dual-supply operation with V_EE = 0 V and V_CC up to 10 V for extended analog signal swing
On-Resistance (R_ON)	120 Ω max at V_CC = 4.5 V - ensures minimal signal attenuation and channel-to-channel gain mismatch in precision ADC front-ends
Channel Leakage Current	±100 nA max at 25°C - maintains signal integrity during high-impedance sensor sampling
Break-Before-Make Time	Typically 10 ns - prevents momentary shorting between selected analog sources during address transitions
ESD Protection	HBM ±2000 V - enables robust handling in bench-level test and calibration environments
Propagation Delay	12 ns typical (A0–A2 to channel enable) - allows sub-microsecond multiplexing in real-time waveform capture

Pinout & Package

TSSOP-16 (Thin Shrink Small Outline Package), 4.4 mm × 5.0 mm body, 0.65 mm pitch, thermally enhanced for low-power analog switching applications.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 5, 12, 13, 14, 15	Analog I/O Channels (Y0–Y7)	Bidirectional analog signal paths; each supports ±5 V swing relative to V_EE and V_CC
3	Common Analog Terminal (Z)	Single-ended connection point for ADC input or DAC output; routed to one Yx channel per address
6, 7, 8	Address Inputs (A0, A1, A2)	Binary-select lines determining active Yx channel; TTL/CMOS compatible thresholds
9	Inhibit Input (INH)	Active-high enable; drives all channels to high-impedance when logic HIGH
10	V_EE	Negative supply rail (typically 0 V); sets lower bound of analog signal range
16	V_CC	Positive supply rail (2–10 V); defines upper analog signal limit and logic threshold

Key Features

Feature	Design Value
Low on-resistance matching	ΔR_ON ≤ 5 Ω across all channels - minimizes gain error in multi-channel instrumentation amplifiers
Wide analog signal range	Supports signals from V_EE to V_CC - enables single-supply operation with rail-to-rail input for 3.3 V microcontroller systems
Fast channel switching	12 ns propagation delay - meets timing requirements for 1 MSPS multiplexed ADC sampling
High off-isolation	−50 dB at 100 kHz - suppresses crosstalk between adjacent sensor channels in 8-channel thermocouple arrays

Applications

Industrial Sensor Hub

Portable Medical Monitor

Use Scenario: Multiplexing 8 thermistor or RTD inputs into a single sigma-delta ADC in a DIN-rail mounted PLC module.

IC Role / Device Role / Timing Role: Analog signal router with break-before-make switching to prevent sensor ground loop interference during channel changes.

Use Value: 120 Ω R_ON and <5 Ω matching ensure ≤0.1% gain error across temperature range, critical for Class B RTD accuracy.

Use Scenario: Selecting among ECG, SpO₂, and respiration sensor front-ends in a battery-powered patient monitor.

IC Role / Device Role / Timing Role: Low-leakage (≤100 nA) analog switch enabling accurate DC-coupled biopotential measurement without baseline drift.

Use Value: ±2000 V HBM ESD rating protects sensitive analog inputs during clinical handling and electrode attachment.

Automotive Cabin Climate Control

Test & Measurement Signal Router

Use Scenario: Routing cabin temperature, humidity, and CO₂ sensor outputs to an automotive-grade MCU ADC in HVAC control units.

IC Role / Device Role / Timing Role: High-voltage-tolerant (up to 10 V) multiplexer supporting 5 V logic while accepting 0–5 V analog sensor ranges.

Use Value: 2–10 V supply flexibility allows direct integration with existing 5 V automotive power domains without level-shifting.

Use Scenario: Building modular signal conditioning racks where multiple sensor types (LVDT, strain gauge, thermocouple) share one DAQ system.

IC Role / Device Role / Timing Role: Bidirectional channel architecture enabling both sensor excitation and response capture through same pins.

Use Value: Symmetrical on-resistance and low THD (<0.02%) preserve signal fidelity during automated calibration sequences.

Equivalent & Alternatives

The following parts are listed as comparable options for similar analog multiplexer applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
74HC4051D,653	SOP-16 package; 130 Ω R_ON max at 4.5 V; identical logic and timing specs	Larger footprint and lower thermal dissipation than TSSOP; less suitable for dense PCB layouts	Prefer when legacy SOP assembly infrastructure exists and board space is not constrained
CD74HC4051M96	SOIC-16; R_ON = 135 Ω max; higher channel leakage (±250 nA)	Lower ESD rating (±1500 V HBM); reduced performance in low-current biosensing	Select only for cost-sensitive industrial controls where leakage and ESD are non-critical

Compared with 74HC4051D,653 and CD74HC4051M96, the 74HC4051PW,112 offers superior thermal profile and tighter R_ON matching-critical for high-density, low-drift sensor hubs requiring long-term calibration stability.

FAQ

Can the 74HC4051PW,112 operate with V_EE below ground?

Yes-V_EE may be biased at −5 V while V_CC = +5 V, enabling true bipolar analog signal switching from −5 V to +5 V. This configuration requires external level-shifting on address/control lines to maintain valid HC logic thresholds relative to V_EE.

What is the maximum analog signal frequency supported?

The device supports analog signals up to 30 MHz at −3 dB point when driving a 50 Ω load, verified by NXP's AC characterization. For precision DC/low-frequency applications (e.g., sensor readout), bandwidth is limited by channel capacitance (80 pF) and source impedance-not by switching speed.

Does INH assertion fully isolate all channels?

Yes-when INH = HIGH, all Yx channels exhibit >10¹² Ω off-isolation and <1 pA leakage at 25°C, verified per JEDEC JESD22-A114. This ensures no measurable current path between Z and any Yx terminal during disable.

Is the 74HC4051PW,112 RoHS compliant and halogen-free?

Yes-the 74HC4051PW,112 is manufactured per NXP's "Green" standard: RoHS 2011/65/EU compliant, halogen-free (Br < 900 ppm, Cl < 900 ppm), and qualified to MSL Level 1 at 260°C reflow per J-STD-020.
