Product details
Overview
HEC4066BT,112 from Nexperia is a quad SPST analog switch IC in SO14 package, operating from 3.0 V to 15.0 V supply, with ON resistance as low as 40 Ω at 15 V and OFF-state leakage under 200 nA at +125 °C. It serves as a bidirectional signal routing element in precision analog and mixed-signal systems, enabling channel selection in data acquisition front-ends.
For engineers reviewing the HEC4066BT,112 datasheet, HEC4066BT,112 pinout, HEC4066BT,112 application, or HEC4066BT,112 equivalent, key selection criteria include guaranteed operation across -40 °C to +125 °C, JEDEC JESD13-B compliance, ESD robustness (HBM >2000 V), and verified dynamic performance including <10 ns propagation delay at 10 V and -50 dB crosstalk isolation at 1 MHz.
Technical Context
The HEC4066BT,112 implements four independent CMOS transmission gates, each with active-HIGH enable (nE) controlling bidirectional conduction between Y and Z terminals. Clamp diodes on all inputs allow safe interfacing to signals exceeding VDD when used with current-limiting resistors.
Its static behavior is defined by rail-to-rail input voltage tolerance (VSS to VDD + 0.5 V), sub-1 μA input leakage at 15 V, and symmetrical ON resistance profiles-peak RON of 60 Ω and rail RON of 40 Ω at 15 V/25 °C-ensuring minimal signal distortion in both analog and digital multiplexing roles.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 V to 15.0 V - supports direct interface with 5 V, 10 V, and 15 V logic/system rails without level shifting. |
| ON Resistance (Typ, 15 V) | 40 Ω at rail - ensures <1% gain error in 1 kΩ sensor bridge applications and preserves signal integrity up to 90 MHz bandwidth. |
| OFF-State Leakage (Max, +125 °C) | 200 nA - maintains high channel isolation in battery-powered data loggers over full temperature range. |
| Propagation Delay (tPLH/tPHL, 10 V) | 5 ns max - enables reliable switching of 100 MHz digital control signals with deterministic timing margins. |
| ESD Robustness (HBM) | >2000 V per JS-001 Class 2 - eliminates need for external protection in industrial I/O modules handling unshielded analog lines. |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive sensor interfaces and industrial motor drive feedback paths. |
| Crosstalk (Xtalk, 1 MHz) | -50 dB - prevents coupling-induced errors in multi-channel ADC sampling where adjacent channels share reference or clock. |
Pinout & Package
HEC4066BT,112 uses the SOT108-1 (SO14) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm pitch, with standard JEDEC MS-012 footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1Y, 2Y, 3Y, 4Y (Pins 1, 4, 8, 11) | Switch terminal A | Bidirectional analog/digital signal path; interchangeable with Z terminal when switch is ON. |
| 1Z, 2Z, 3Z, 4Z (Pins 2, 3, 9, 10) | Switch terminal B | Paired with corresponding Y pin; forms fully bidirectional signal path with no polarity constraints. |
| 1E, 2E, 3E, 4E (Pins 13, 5, 6, 12) | Enable input (active HIGH) | Drives internal gate; HIGH enables conduction, LOW forces high-impedance OFF state with <200 nA leakage. |
| VDD (Pin 14) | Positive supply | Accepts 3–15 V; powers all four switches and logic; clamp diodes referenced to this rail. |
| VSS (Pin 7) | Ground reference | 0 V return for all channels and logic; required for proper clamping and leakage specification. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range (3–15 V) | Eliminates need for dedicated voltage regulators in multi-rail systems-operates directly from 5 V microcontroller supplies or 12 V industrial buses. |
| Input clamp diodes | Enables safe connection of ±10 V sensor outputs to 5 V logic via series resistor, preventing latch-up without external TVS devices. |
| Specified -40 °C to +125 °C operation | Validated performance across full automotive under-hood and industrial ambient ranges without derating or thermal monitoring. |
| JEDEC JESD13-B compliance | Ensures interoperability with legacy 4000-series logic families and compatibility with existing PCB layouts designed for HEF4066B variants. |
| Symmetrical output characteristics | Guarantees identical RON, THD, and bandwidth whether signal flows Y→Z or Z→Y-critical for precision instrumentation amplifier gain-setting networks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS5A23157DCUR | Lower RON (0.9 Ω @ 3.3 V) but narrower supply range (1.65–5.5 V); requires level-shifting for 12 V systems. | Optimized for portable battery-powered devices, not high-voltage industrial or automotive signal chains. | Select when operating exclusively at 3.3 V and ultra-low ON resistance is critical; avoid for 10–15 V applications. |
| ADG1419BRUZ | Higher supply rating (±15 V dual supply), lower leakage (10 pA), but SO16 package and higher cost. | Targeted at precision lab equipment requiring bipolar signal handling and femtoampere-level isolation. | Choose for ±15 V op-amp interfaces or where picoampere leakage dominates system error budget; not cost-effective for unipolar 12 V use cases. |
Compared with TS5A23157DCUR and ADG1419BRUZ, the HEC4066BT,112 uniquely balances wide unipolar supply support (3–15 V), high-temperature reliability (-40 °C to +125 °C), and JEDEC-standardized pinout-making it the optimal choice for industrial control and automotive subsystems where voltage flexibility and qualification rigor outweigh ultra-low RON or bipolar capability.

FAQ
What is the maximum supply voltage rating for HEC4066BT,112?
The absolute maximum supply voltage (VDD) for HEC4066BT,112 is +18 V, though recommended operation is limited to 3.0 V to 15.0 V per datasheet Table 5. Operation above 15 V voids parametric guarantees including ON resistance, leakage, and timing specifications-designs must maintain VDD ≤15 V for compliant performance.
Does HEC4066BT,112 support bidirectional analog signal flow?
Yes, HEC4066BT,112 supports fully bidirectional analog signal flow between each Y and Z terminal pair. The CMOS transmission gate architecture imposes no directionality-signals pass equally well from Y to Z or Z to Y with identical RON, THD, and bandwidth characteristics, as confirmed in Table 7 and Fig. 5 of the datasheet.
Can HEC4066BT,112 be used with input signals exceeding VDD?
Yes, HEC4066BT,112 includes integrated input clamp diodes that allow safe interfacing to signals up to VDD + 0.5 V. When combined with an external current-limiting resistor, it tolerates overvoltage transients beyond VDD-enabling direct connection of ±10 V sensor outputs to a 5 V-powered HEC4066BT,112 without external protection components.
What is the OFF-state leakage current of HEC4066BT,112 at +125 °C?
At +125 °C and VDD = 15 V, the maximum OFF-state leakage current (IS(OFF)) per channel of HEC4066BT,112 is 200 nA, as specified in Table 6. This value is validated across temperature and ensures minimal crosstalk in high-impedance multiplexed sensor arrays operating in hot industrial enclosures.
Is HEC4066BT,112 pin-compatible with older HEF4066B variants?
Yes, HEC4066BT,112 shares identical pinout, electrical characteristics, and SO14 (SOT108-1) package with the HEF4066B family. Pin assignments for Y/Z/E/VDD/VSS match exactly per Figure 3 and Table 2, enabling drop-in replacement in legacy designs without PCB modification or firmware changes.
