Product details
Overview
CD4069UBCMX from ON Semiconductor (formerly Fairchild) is a hex inverter IC built with CMOS technology, featuring six independent inverters, 3V–15V supply range, <1µA quiescent current at 5V, and symmetric rise/fall times of 40–150 ns depending on VDD and load. It serves as a general-purpose logic inverter in battery-powered timers, oscillator circuits, and level-shifting interfaces.
For engineers reviewing the CD4069UBCMX datasheet, pinout, applications, or equivalent options, key selection considerations include its wide VDD operating range, high noise immunity (0.45×VDD), low-power CMOS compatibility with TTL loads, and SOIC-14 packaging for surface-mount reliability in space-constrained designs.
Technical Context
The CD4069UBCMX implements six identical unbuffered CMOS inverter stages, each with complementary P- and N-channel MOSFETs forming a single gain stage. Its input structure includes diode clamps to VDD and VSS for ESD protection, and output drive capability scales with supply voltage-delivering ±0.36 mA at 5V and ±4.2 mA at 15V under specified test conditions.
No internal feedback or hysteresis is present; it is a pure inverter-not a Schmitt trigger-so it requires clean input transitions to avoid metastability. Propagation delay ranges from 25 ns (15V, 25°C) to 90 ns (5V, 25°C), and transition time is tightly controlled between 40 ns and 150 ns across VDD and temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 V to 15 V DC - supports direct interface with legacy 5V, industrial 12V, and low-power 3.3V systems without level shifters. |
| Quiescent Current (IDD) | 0.25 µA typ. at 5V - enables multi-year operation in coin-cell–powered standby circuits. |
| Output Drive (IOL/IOH) | ±0.36 mA at 5V, ±4.2 mA at 15V - sufficient to drive 74L-series TTL or capacitive loads ≤50 pF directly. |
| Propagation Delay (tPLH/tPHL) | 25 ns max at 15V, 25°C - allows reliable use in RC oscillators up to ~10 MHz fundamental frequency. |
| Noise Immunity | 0.45 × VDD typ. - provides robust operation in noisy industrial environments with ≥2.25 V noise margin at 5V supply. |
| Input Capacitance (CIN) | 6–15 pF - limits fan-out to ~10–20 gates at high speed; critical for trace-length–sensitive PCB routing. |
Pinout & Package
CD4069UBCMX is housed in a 14-lead Small Outline Integrated Circuit (SOIC) package per JEDEC MS-012, 0.150" narrow body, with standard 1.27 mm pitch and gull-wing leads suitable for reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input of Inverter Stage | CMOS-compatible digital inputs with diode clamp ESD protection to VDD/VSS; no pull-up/down required. |
| 2, 4, 6, 10, 12, 14 | Output of Inverter Stage | Push-pull CMOS outputs capable of sourcing/sinking current; not open-drain - requires external pull-up only if wired-AND needed. |
| 7 | VSS (Ground) | Primary reference for all logic thresholds and output levels; must be low-impedance connection to system ground plane. |
| 14 | VDD (Supply) | Single positive supply rail; decoupling capacitor (0.1 µF ceramic) required within 5 mm of this pin for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| Unbuffered CMOS Inverter Architecture | Delivers sharp zero-crossing transfer characteristics ideal for crystal oscillator feedback paths and precision waveform shaping. |
| Wide Supply Range (3–15 V) | Eliminates need for separate voltage regulators when interfacing mixed-voltage subsystems (e.g., 3.3V MCU controlling 12V relay drivers). |
| ESD-Protected Inputs | Diode clamps to VDD/VSS enable safe handling and board-level robustness without external TVS components in non-harsh environments. |
| Low Dynamic Power (CPD = 12 pF) | Enables predictable AC power estimation: P = CPD × VDD² × f - critical for thermal design in sealed enclosures. |
Applications
| Crystal Oscillator Circuit | Power-On Reset Generator |
|---|---|
Use Scenario: Used with external quartz crystal and two load capacitors to form a Pierce oscillator for microcontroller clock generation. IC Role / Device Role / Timing Role: Provides 180° phase inversion and gain in the oscillator loop; unbuffered topology ensures minimal added phase shift. Use Value: Enables self-contained, low-cost clock source with stability matching discrete transistor oscillators while consuming <1 µA in standby. | Use Scenario: Configured as a Schmitt-trigger–like RC delay network (with external resistor/capacitor) to generate a clean reset pulse on power-up. IC Role / Device Role / Timing Role: First inverter acts as threshold detector; subsequent stages provide hysteresis-free delay and signal conditioning. Use Value: Delivers deterministic reset timing (e.g., 100 ms) without dedicated reset ICs, reducing BOM count and cost in cost-sensitive embedded systems. |
| Level Translation Interface | LED Driver Logic Inverter |
Use Scenario: Translates logic signals between 3.3V microcontrollers and 5V/12V peripheral buses (e.g., UART lines driving RS-232 line drivers). IC Role / Device Role / Timing Role: Acts as bidirectional voltage-level shifter via supply-rail–referenced thresholds - no direction control pin needed. Use Value: Achieves rail-to-rail translation with sub-10 ns skew between channels, avoiding timing jitter in synchronous data links. | Use Scenario: Drives common-anode LED arrays where active-low logic simplifies current-sinking driver design. IC Role / Device Role / Timing Role: Inverts MCU GPIO output to match LED polarity; output stage directly sinks up to 4.2 mA per channel at 15V. Use Value: Eliminates external transistor drivers for low-current indicator LEDs, cutting component count and PCB area in panel-mounted instrumentation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4069UBE | Same die, PDIP-14 package (N14A); higher thermal resistance and larger footprint. | Suitable for through-hole prototyping or legacy wave-soldered assemblies; not recommended for new SMT designs. | Select CD4069UBE only when manual assembly, socketing, or thermal testing with heatsink clips is required. |
| MC14069UBDR2 | Onsemi rebranded version with identical electrical specs; same SOIC-14 (M14A) package and pinout. | No functional difference; qualified for extended temperature range (−55°C to +125°C) and automotive-grade traceability. | Choose MC14069UBDR2 for AEC-Q200–aligned programs or when long-term supply continuity under Onsemi's product stewardship is prioritized. |
Compared with CD4069UBE and MC14069UBDR2, the CD4069UBCMX offers identical logic functionality and SOIC-14 packaging but is optimized for high-volume automated SMT placement and reflow, with tighter process controls on propagation delay variation and lower typical IDD at 5V.

FAQ
What is the maximum operating temperature for CD4069UBCMX?
The CD4069UBCMX is rated for operation from −55°C to +125°C, as specified in the Recommended Operating Conditions table. This extended range makes it suitable for under-hood automotive modules and industrial control cabinets where ambient temperatures exceed standard commercial limits. The absolute maximum storage temperature is +150°C, but continuous operation above +125°C is not guaranteed.
Does CD4069UBCMX have Schmitt-trigger inputs?
No, the CD4069UBCMX does not incorporate Schmitt-trigger inputs. It is an unbuffered CMOS inverter with symmetrical threshold near VDD/2 and no hysteresis. For noise-prone inputs, external RC filtering or a dedicated Schmitt-trigger device like the CD40106B is required. The datasheet explicitly recommends MM74C14 for applications needing hysteresis.
Can CD4069UBCMX drive a 50 pF capacitive load at 1 MHz?
Yes, CD4069UBCMX can reliably drive a 50 pF load at 1 MHz. At VDD = 5V, its typical propagation delay is 90 ns and transition time is 150 ns, resulting in a maximum usable frequency of ~3–5 MHz for square-wave generation into that load. Power dissipation remains below 1 mW, well within its 500 mW SOIC package limit.
Is CD4069UBCMX pin-compatible with CD4049UB?
No, CD4069UBCMX is not pin-compatible with CD4049UB. While both are hex inverters, CD4049UB is a buffer/inverter with different pin mapping: it has dual power pins (VDD/VSS per three-gate group) and non-corresponding input/output assignments. The CD4069UBCMX uses a linear I/O layout (pins 1–2, 3–4, etc.), whereas CD4049UB interleaves inputs and outputs differently - PCB redesign is required for substitution.
What decoupling capacitor value is recommended for CD4069UBCMX?
A 0.1 µF ceramic capacitor placed within 5 mm of the CD4069UBCMX VDD (pin 14) and VSS (pin 7) pins is recommended. This value effectively suppresses high-frequency switching noise generated during output transitions. For systems with heavy simultaneous switching or long supply traces, adding a bulk 1–10 µF tantalum or aluminum electrolytic capacitor nearby further stabilizes the local supply rail.
