Product details
Overview
74LV4066N,112 from NXP Semiconductors (formerly Philips) is a quad bilateral analog switch IC designed for low-voltage signal routing in mixed-signal systems. It features four independent SPST switches with active-HIGH enable inputs, 25 Ω typical ON-resistance at 4.5 V, 8 pF maximum switch capacitance, and operation from 1.0 V to 6.0 V supply. It is used in audio signal switching, sensor multiplexing, and digital I/O isolation circuits.
For engineers reviewing the 74LV4066N,112 datasheet, 74LV4066N,112 pinout, 74LV4066N,112 application, or 74LV4066N,112 equivalent, this page delivers verified functional specifications, DIP14 package details, temperature-rated performance (−40 °C to +125 °C), TTL-input compatibility at 2.7–3.6 V, and real-world crosstalk/switching metrics including −60 dB inter-channel isolation and 10 ns turn-on time at 3.3 V.
Technical Context
The 74LV4066N,112 implements four independent CMOS transmission gates controlled by separate enable inputs (1E–4E), each supporting bidirectional analog/digital signal flow between Y and Z terminals. Its Si-gate low-voltage architecture ensures rail-to-rail analog conduction with minimal distortion (<0.04% sine-wave THD at 1 kHz).
It operates across a wide voltage range (1.0–6.0 V) while maintaining specified timing: 10 ns turn-on and 13 ns turn-off at VCC = 3.3 V, CL = 15 pF. The device meets IEC 60134 limiting values and supports industrial-grade ambient operation up to +125 °C in the DIP14 package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.0 V to 6.0 V - Enables direct interface with 1.2 V, 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| ON-Resistance (Typ) | 25 Ω at VCC = 4.5 V - Ensures low insertion loss and minimal signal attenuation for analog signals up to 180 MHz bandwidth. |
| Switch Capacitance | 8 pF max - Limits capacitive loading on driven nodes, preserving signal integrity in high-speed multiplexing. |
| Turn-On Time | 10 ns at VCC = 3.3 V, CL = 15 pF - Supports fast channel selection in data acquisition and real-time control loops. |
| Crosstalk Attenuation | −60 dB at 1 MHz - Prevents signal coupling between enabled and disabled channels in multi-sensor systems. |

| 1E, 2E, 3E, 4E | Enable input (active HIGH) | Drives switch ON when logic HIGH (VIH ≥2.0 V at VCC=2.7–3.6 V); no external pull-up required. |
| VCC | Positive supply | Single power rail powers all four switches and logic; decoupling capacitor recommended at pin 14. |
| GND | Ground reference | Common return for analog signals and digital control; must be low-impedance to minimize ground bounce. |
Key Features

FAQ
What is the maximum operating supply voltage for the 74LV4066N,112?
The 74LV4066N,112 supports a maximum supply voltage of +7.0 V under absolute maximum ratings, but its recommended operating range is 1.0 V to 6.0 V. Operation above 6.0 V risks exceeding safe power dissipation limits and may degrade long-term reliability. For sustained use, VCC should remain ≤6.0 V per Table 5 in the datasheet.
Does the 74LV4066N,112 support bidirectional analog signal switching?
Yes, the 74LV4066N,112 supports true bidirectional analog switching on all four channels. Each switch consists of a CMOS transmission gate connecting pins nY and nZ; signal flow direction is determined solely by external circuitry-not by internal polarity-enabling flexible routing in both directions without performance penalty.
Can the 74LV4066N,112 be used with 5 V logic inputs while powered at 3.3 V?
No-the 74LV4066N,112 does not tolerate 5 V inputs when VCC = 3.3 V. Its absolute maximum input voltage is VCC + 0.5 V (i.e., 3.8 V). Applying 5 V violates the limiting value in Table 5 and risks permanent damage. Use level-shifting circuitry or select a 5 V-tolerant variant like 74LVT4066 if interfacing with 5 V controllers.
What is the typical ON-resistance flatness specification for the 74LV4066N,112?
The 74LV4066N,112 exhibits ON-resistance flatness of ≤5 Ω (typical) across the signal range when VCC = 2.0 V, improving to ≤3 Ω at VCC = 4.5 V (Table 8). This tight flatness ensures minimal harmonic distortion and consistent gain in audio and precision analog paths, especially critical in AC-coupled applications.
Is the 74LV4066N,112 RoHS compliant and lead-free?
Yes, the 74LV4066N,112 is RoHS compliant and lead-free. As a NXP product manufactured post-2006, it conforms to Directive 2011/65/EU and uses lead-free matte tin terminations on its DIP14 package (SOT27-1). Full compliance documentation is available in NXP's official product change notices and material declarations.
