Product details
Overview
HEF4069UBT/AUJ from Nexperia is a hex unbuffered CMOS inverter IC operating from 3.0 V to 15.0 V, featuring six independent inverting gates with clamp diodes on all inputs for overvoltage interface protection, symmetrical output drive, and specified operation from −40 °C to +125 °C - used in oscillator circuits, analog amplifiers, and logic-level translation.
For engineers reviewing the HEF4069UBT/AUJ datasheet, HEF4069UBT/AUJ pinout, HEF4069UBT/AUJ application, or HEF4069UBT/AUJ equivalent, key selection considerations include supply voltage range (3–15 V), propagation delay (15–90 ns depending on VDD and load), input clamping capability, SO14 package compatibility, and −40 °C to +125 °C industrial temperature rating.
Technical Context
The HEF4069UBT/AUJ implements six identical unbuffered inverter stages using standard CMOS technology, each with input clamp diodes enabling safe interfacing to voltages exceeding VDD when used with current-limiting resistors. Its static operation supports zero-static-power latching and stable DC logic levels across full temperature and supply ranges.
Dynamic behavior is characterized by VDD-dependent propagation delays (e.g., typ. 15 ns at 15 V/50 pF) and transition times governed by load capacitance, with typical dynamic power dissipation modeled as PD = 22000 × fi + Σ(fo × CL) × VDD² (μW) at 15 V. Input leakage remains ≤ ±1.0 μA at 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 V to 15.0 V - supports single-rail operation across 5 V, 10 V, and 15 V logic systems without level shifters. |
| Operating Temperature | −40 °C to +125 °C - qualified for extended industrial environments including motor control and power supply monitoring. |
| Propagation Delay (tPHL/tPLH) | 15 ns (typ.) at 15 V/50 pF - enables reliable timing in crystal oscillators and relaxation oscillators up to ~10 MHz. |
| Input Clamp Diodes | Integrated on all six inputs - permits direct connection to signals > VDD when series current-limiting resistors are used. |
| Output Drive Capability | ±2.4 mA (min) at 15 V, VO = 1.5 V / 13.5 V - sufficient to drive multiple CMOS loads or small capacitive nodes without buffering. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - meets JEDEC JS-001/JS-002 Class 2/C3 for robust handling in automated assembly. |
| Static Power Dissipation | < 1.0 μA IDD (typ.) at 25 °C, < 30.0 μA at 125 °C - enables ultra-low-quiescent-current standby modes in battery-backed systems. |
Pinout & Package
HEF4069UBT/AUJ is supplied in the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | 1A–6A | Six independent logic inputs; each includes internal clamp diodes to VSS and VDD for overvoltage tolerance. |
| 2, 4, 6, 8, 10, 12 | 1Y–6Y | Six complementary inverted outputs; symmetrical rise/fall characteristics support clean square-wave generation. |
| 7 | VSS | Ground reference (0 V); must be low-impedance connection to minimize noise coupling between inverters. |
| 14 | VDD | Positive supply rail; decoupling capacitor (e.g., 100 nF) required near pin for stable high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Unbuffered Inverter Architecture | Enables use as analog amplifier (bias point set via feedback resistor) or linear oscillator stage - not possible with buffered logic gates. |
| Wide-Voltage Parametric Ratings | Guaranteed performance at 5 V, 10 V, and 15 V allows reuse across legacy and modern industrial control rails without redesign. |
| JEDEC JESD13-B Compliance | Ensures interoperability with other industry-standard CMOS logic families and predictable timing margins in mixed-voltage systems. |
| High Noise Immunity | Typical VIH/VIL thresholds at 80 %/20 % of VDD provide >3 V noise margin at 15 V supply - critical in electrically noisy motor drives. |
| Standardized Output Characteristics | Matched rise/fall times and drive strength across all six channels simplify timing analysis in multi-stage oscillator or delay networks. |
Applications
| Oscillator Circuits | Analog Signal Conditioning |

IC Role / Device Role / Timing Role: Robust logic buffer with high noise immunity and ESD-hardened inputs. Use Value: 2000 V HBM ESD rating and >3 V noise margin at 15 V ensure reliable operation in high-noise industrial cabinets without added protection circuitry. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4069UBM96 (TI) | Same pinout, identical unbuffered architecture, but rated only to +85 °C and lacks JESD13-B compliance. | Not suitable for automotive under-hood or industrial high-temp control cabinet use above 85 °C. | Select CD4069UBM96 only if ambient temperature stays ≤85 °C and JEDEC compliance is not required. |
| 74HC04PW,118 (Nexperia) | Buffered architecture, higher speed (typ. 7 ns @ 5 V), but no input clamp diodes and narrower 2–6 V supply range. | Cannot interface directly to voltages > VDD; unsuitable for analog amplifier or overvoltage-tolerant designs. | Choose 74HC04PW,118 only for high-speed digital inversion where supply is strictly 5 V and overvoltage protection is handled externally. |
Compared with CD4069UBM96 and 74HC04PW,118, the HEF4069UBT/AUJ uniquely combines industrial temperature range (−40 °C to +125 °C), input clamp diodes, and JEDEC compliance - making it the only option among the three for unbuffered, high-temp, overvoltage-tolerant inverter applications.

FAQ
What is the maximum supply voltage rating for HEF4069UBT/AUJ?
The absolute maximum supply voltage (VDD) for HEF4069UBT/AUJ is +18 V, but the recommended operating range is 3.0 V to 15.0 V per datasheet Table 4. Operation above 15 V voids parametric guarantees and risks accelerated aging; sustained use at 18 V is limited to transient conditions only.
Can HEF4069UBT/AUJ be used as an analog amplifier?
Yes, HEF4069UBT/AUJ can operate in linear mode as an analog inverting amplifier when biased with a high-value feedback resistor (e.g., 560 kΩ), as shown in Figure 11 of the datasheet. Its unbuffered structure and transfer characteristics (Fig. 6) enable usable gain - though precision and bandwidth are limited compared to dedicated op-amps.
Does HEF4069UBT/AUJ support operation at −40 °C to +125 °C?
Yes, HEF4069UBT/AUJ is fully specified and tested for operation across −40 °C to +125 °C ambient temperature (Table 4, Ordering Information). This rating applies to the SO14 (SOT108-1) package variant and is validated per JEDEC JESD13-B requirements.
What is the purpose of the input clamp diodes in HEF4069UBT/AUJ?
The input clamp diodes in HEF4069UBT/AUJ protect against voltages exceeding VDD or falling below VSS. When used with external current-limiting resistors, they allow safe interfacing to signals up to VDD + 0.5 V or down to VSS − 0.5 V - enabling direct connection to higher-voltage sensors or legacy logic without level-shifting circuitry.
Is HEF4069UBT/AUJ pin-compatible with CD4069UB?
Yes, HEF4069UBT/AUJ is pin-compatible with CD4069UB in SO14 packaging: both share identical pin 1–14 assignments (six inputs, six outputs, VSS, VDD). However, HEF4069UBT/AUJ offers superior temperature range (−40 °C to +125 °C vs. −40 °C to +85 °C), tighter parametric specs, and JEDEC JESD13-B compliance not found in standard CD4069UB variants.
