Product details
Overview
74LV4066DB,118 from Nexperia is a quad SPST analog switch IC with bilateral signal routing capability, active-HIGH enable control per channel, 25 Ω typical ON-resistance at 4.5 V supply, and operation across 1.0–6.0 V supply range. It supports analog/digital signal switching in mixed-signal interfaces requiring low distortion and rail-to-rail voltage handling up to VCC.
For engineers reviewing the 74LV4066DB,118 datasheet, 74LV4066DB,118 pinout, 74LV4066DB,118 application, or 74LV4066DB,118 equivalent, key selection criteria include guaranteed operation down to 1.0 V, -40 °C to +125 °C temperature rating, SO14 package compatibility, and sub-15 ns turn-on/turn-off times at 3.3 V.
Technical Context
The 74LV4066DB,118 implements four independent CMOS transmission gates, each with symmetrical Y/Z terminals enabling bidirectional analog or digital signal flow. Each channel features a dedicated enable input (nE) that controls conduction state without polarity inversion.
Its design integrates clamp diodes on all digital inputs for overvoltage tolerance, supports direct TTL-level interfacing, and maintains low ground bounce (<0.8 V at 3.3 V), making it suitable for noise-sensitive mixed-signal routing where signal integrity and supply flexibility are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0 V to 6.0 V - Enables direct integration into 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V systems without level shifters. |
| ON-Resistance (Typ) | 25 Ω at VCC = 4.5 V - Ensures minimal insertion loss and voltage drop for analog signals up to ±25 mA per switch. |
| Turn-On Time (Typ) | 10 ns at VCC = 3.3 V, CL = 15 pF - Supports high-speed multiplexing of digital control signals and medium-frequency analog waveforms. |
| OFF-State Leakage (Max) | 2.0 μA at VCC = 6.0 V - Maintains signal isolation in battery-powered or high-impedance sensor front-ends. |
| Operating Temperature | -40 °C to +125 °C - Qualified for industrial and extended-temperature embedded applications without derating. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Reduces need for external protection in board-level ESD-prone environments. |
| Switch Capacitance | 8 pF maximum - Limits capacitive loading on source and load nodes, preserving bandwidth in RF-adjacent signal paths. |
Pinout & Package
74LV4066DB,118 is supplied in SO14 (SOT108-1) package: plastic small outline, 14-lead, 3.9 mm body width, 1.27 mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1Y, 4Y, 8Y, 11Y | Switch terminal A (bidirectional) | Independent analog/digital I/O node per channel; interchangeable with Z pin for bilateral routing. |
| 2Z, 3Z, 9Z, 10Z | Switch terminal B (bidirectional) | Paired with corresponding Y pin; forms fully symmetric conductive path when enabled. |
| 13, 5, 6, 12 | Enable inputs (1E–4E) | Active-HIGH logic control: HIGH enables conduction, LOW forces high-impedance OFF-state. |
| 7 | GND | Reference ground for all internal circuitry and signal return path. |
| 14 | VCC | Primary power supply input; powers internal logic and switch transistors; supports 1.0–6.0 V operation. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | Operates from 1.0 V to 6.0 V - eliminates need for separate voltage rails in multi-supply systems. |
| Bilateral signal routing | Fully symmetrical Y/Z terminals - supports analog AC coupling, audio routing, and bidirectional data bus switching. |
| Low ON-resistance flatness | RON(flat) ≤2 Ω at VCC = 6.0 V - minimizes harmonic distortion and amplitude variation across input voltage swing. |
| Input clamp diodes | Enables safe interface to voltages exceeding VCC - allows use with current-limiting resistors for overvoltage-tolerant I/O. |
| High OFF-state attenuation | αOFF(feedthru) ≥50 dB at 1 MHz - suppresses crosstalk and feed-through in precision analog multiplexing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74LVC4066PW,118 | Lower ON-resistance (15 Ω typ @ 3.3 V); narrower supply range (1.65–3.6 V); TSSOP14 only. | Better performance in 3.3 V-only systems; unsuitable for 1.0–1.6 V or 5 V operation. | Select when optimizing for lowest RON in 3.3 V designs and PCB space permits TSSOP14 footprint. |
| SN74LV4066ADBR | Identical electrical specs; SOIC-14 package; Texas Instruments branding and qualification. | No functional difference; TI's documentation and support ecosystem preferred in certain OEM programs. | Choose for dual-sourcing flexibility or TI-aligned design workflows; pinout and timing match exactly. |

FAQ
What is the minimum supply voltage required for guaranteed operation of the 74LV4066DB,118?
The 74LV4066DB,118 is guaranteed to function down to 1.0 V supply voltage, with static characteristics specified from 1.2 V to 5.5 V. At 1.0–1.2 V, operation is functional but ON-resistance becomes highly non-linear, so digital signal routing is recommended over analog use below 1.2 V. The 74LV4066DB,118 maintains valid logic thresholds and switching behavior across this full range.
Does the 74LV4066DB,118 support bidirectional analog signal routing?
Yes, the 74LV4066DB,118 supports true bidirectional analog signal routing via its symmetrical Y and Z terminals per channel. Each switch conducts equally well in either direction when enabled, with matched ON-resistance flatness (≤2 Ω) and low crosstalk (≥60 dB), making it suitable for AC-coupled audio, sensor differential pairs, and bus isolation where signal polarity must be preserved.
What is the maximum allowable switch current for the 74LV4066DB,118?
The absolute maximum switch current for the 74LV4066DB,118 is ±25 mA per channel, as defined in the limiting values table. This applies across the full operating temperature range (-40 °C to +125 °C) and supply voltage range (1.0–6.0 V). Exceeding this value risks permanent damage, and continuous operation near this limit requires thermal derating per the package-specific Ptot derating curves.
How does the 74LV4066DB,118 handle input voltages exceeding VCC?
The 74LV4066DB,118 includes integrated clamp diodes on all digital inputs (enable pins), allowing safe interface to voltages up to VCC + 0.5 V or down to -0.5 V relative to GND. To use this feature, external current-limiting resistors must be added to restrict input clamping current to ≤±20 mA, as specified in the absolute maximum ratings. The 74LV4066DB,118 does not provide overvoltage protection on Y/Z analog terminals.
Is the 74LV4066DB,118 qualified for automotive applications?
No, the 74LV4066DB,118 is not automotive-qualified. Nexperia explicitly states in the revision history and legal disclaimers that unless otherwise stated in the datasheet, products are non-automotive qualified. The 74LV4066DB,118 is rated for industrial temperature range (-40 °C to +125 °C) but has not undergone AEC-Q100 stress testing or automotive-specific qualification. For automotive use, consult Nexperia's automotive-grade alternatives.
