Product details
Overview
74HC4066PW,112 from Nexperia is a quad SPST analog switch IC designed for bidirectional signal routing in mixed-signal systems. It features four independent switches with active-HIGH enable inputs (1E–4E), low ON resistance (35 Ω typical at 9 V), ±25 mA switch current rating, and operation across -40 °C to +125 °C - used in audio multiplexing, sensor interface conditioning, and test equipment signal path control.
For engineers reviewing the 74HC4066PW,112 datasheet, 74HC4066PW,112 pinout, 74HC4066PW,112 application, or 74HC4066PW,112 equivalent, key selection criteria include guaranteed 9 V supply compatibility, TSSOP14 package thermal performance, channel-to-channel isolation (-60 dB at 1 MHz), and CMOS-level input compatibility with rail-to-rail analog signal handling up to VCC.
Technical Context
The 74HC4066PW,112 implements four independent bilateral analog switches using standard CMOS transmission gate architecture. Each switch connects Yn and Zn terminals when its corresponding enable input (nE) is HIGH, with no polarity dependence - supporting AC/DC signals within GND–VCC range. Input clamping diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors.
Switch behavior is defined by static RON characteristics that vary with input voltage (Vis) and supply level: RON(peak) = 32 Ω (typ) at VCC = 9 V and Vis = VCC–GND, while RON(rail) drops to 20 Ω (typ) at Vis = GND or VCC. Dynamic performance includes 10 ns max propagation delay (VCC = 9 V) and -3 dB bandwidth of 200 MHz under 50 Ω load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0 V to 10.0 V - supports wide-range digital logic and analog signal swing without level-shifting circuitry |
| ON Resistance (RON) | 35 Ω typical at VCC = 9.0 V - enables low-insertion-loss signal routing for audio and precision sensor paths |
| Switch Current | ±25 mA per channel - sufficient for driving DAC outputs, op-amp feedback networks, or LED bias paths |
| Isolation (OFF-state) | -50 dB at 1 MHz - suppresses crosstalk between inactive channels in multi-channel data acquisition |
| Propagation Delay | 10 ns max at VCC = 9.0 V - ensures timing integrity in high-speed digital control of analog signal chains |
| Operating Temperature | -40 °C to +125 °C - qualified for automotive under-hood, industrial PLC I/O, and harsh-environment instrumentation |
| ESD Protection | HBM >2000 V, CDM >1000 V - reduces risk of field failure during board assembly and system integration |
Pinout & Package
TSSOP14 (SOT402-1) plastic thin shrink small outline package: 14-lead, 4.4 mm body width, 0.65 mm pitch, 1.20 mm max height - optimized for high-density PCB layouts with improved thermal dissipation over SO14.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1Y, 2Y, 3Y, 4Y | Analog I/O terminal (Y-side) | Bidirectional signal port paired with corresponding Z terminal; interchangeable as input or output |
| 1Z, 2Z, 3Z, 4Z | Analog I/O terminal (Z-side) | Complementary port to Y terminal; forms fully symmetric analog switch path |
| 1E, 2E, 3E, 4E | Enable input (active HIGH) | Controls ON/OFF state of respective switch; TTL-compatible threshold not required (CMOS logic) |
| VCC | Positive supply rail | Power source for internal logic and switch conduction; must be decoupled locally with 100 nF ceramic capacitor |
| GND | Ground reference | Common return for all analog and digital currents; requires low-impedance connection to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Bidirectional analog switching | Enables flexible signal routing without directionality constraints - ideal for shared bus architectures and reconfigurable test fixtures |
| Low and flat ON resistance | RON variation <3 Ω across Vis range at VCC = 9 V - preserves signal amplitude accuracy in precision measurement front-ends |
| Input clamp diodes | Permits safe overvoltage tolerance up to VCC + 0.5 V with external current limiting - eliminates need for discrete protection components |
| High OFF-state isolation | -60 dB crosstalk between enabled and disabled switches at 1 MHz - maintains channel independence in multi-signal systems |
| JEDEC-compliant packaging | SOT402-1 footprint compatible with automated SMT placement and reflow profiles - supports high-yield manufacturing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT4066PW,112 | TTL-compatible input thresholds (VIH = 2.0 V min); identical RON, timing, and package | Required when driving from legacy 5 V TTL logic without level shifters | Select 74HCT4066PW,112 only if system uses 5 V TTL signaling; otherwise 74HC4066PW,112 offers wider VCC range and lower static power |
| TS5A23157DCUR | Lower RON (0.9 Ω typ at 4.5 V), but rated only to 5.5 V VCC and -40 °C to +85 °C | Not suitable for 9 V analog rails or extended temperature industrial use | Choose TS5A23157DCUR only for low-voltage, high-speed consumer applications where ultra-low RON justifies reduced voltage/temp margin |
Compared with 74HCT4066PW,112 and TS5A23157DCUR, the 74HC4066PW,112 uniquely balances 9 V operation, 125 °C rating, and proven robustness in industrial signal routing - making it the default choice when wide supply range and extended temperature capability are mandatory.

FAQ
What is the maximum supply voltage rating for the 74HC4066PW,112?
The 74HC4066PW,112 supports a maximum supply voltage of +11.0 V (absolute maximum) with recommended operation up to 10.0 V. Operating at 9.0 V yields optimal ON resistance (35 Ω typical) and bandwidth (200 MHz), making the 74HC4066PW,112 suitable for high-fidelity analog routing where headroom above 5 V is required.
Does the 74HC4066PW,112 support bidirectional analog signal flow?
Yes, the 74HC4066PW,112 provides fully bidirectional signal conduction between each Y–Z pair. There is no designated input or output terminal - either Yn or Zn may serve as source or sink depending on system topology. This symmetry is inherent to its CMOS transmission gate structure and confirmed in the functional diagram and pin description tables of the official Nexperia datasheet for 74HC4066PW,112.
How does the 74HC4066PW,112 handle input voltages exceeding VCC?
The 74HC4066PW,112 integrates input clamp diodes on all control (nE) and analog (Y/Z) pins. When voltages exceed VCC + 0.5 V or fall below GND – 0.5 V, these diodes conduct - but only safely if external current-limiting resistors restrict clamp current to ≤±20 mA. This feature allows direct interfacing to higher-voltage sensors or legacy buses without added protection circuitry, as specified in the 74HC4066PW,112 limiting values table.
What is the thermal performance of the TSSOP14 package used by the 74HC4066PW,112?
The 74HC4066PW,112 in SOT402-1 (TSSOP14) has a total power dissipation limit of 500 mW at Tamb ≤ 81 °C, derating linearly at 7.3 mW/K above that temperature. Its 4.4 mm body width and exposed pad-free construction provide better thermal resistance than SO14 but less than QFN variants - making it appropriate for moderate-power analog switching in space-constrained industrial PCBs where airflow is limited.
Can the 74HC4066PW,112 be used with 3.3 V logic control signals?
Yes - the 74HC4066PW,112 accepts CMOS-level inputs, so a 3.3 V HIGH signal meets VIH requirements across its full VCC range (2.0–10.0 V). At VCC = 5 V, VIH(min) = 3.15 V; at VCC = 9 V, VIH(min) = 6.3 V. Therefore, 3.3 V control is valid only when VCC ≤ 5.0 V. For 9 V operation, level-shifting or 74HCT4066PW,112 (TTL-compatible) is required - confirming precise voltage domain matching is essential for reliable 74HC4066PW,112 use.
