Product details
Overview
MC14069UBDG from onsemi is a hex inverter IC built with CMOS P-channel and N-channel enhancement-mode transistors in a monolithic structure, delivering six independent single-stage inverters. It operates across 3.0–18.0 VDC supply, supports −55°C to +125°C ambient, and achieves propagation delays as low as 30 ns (at VDD = 15 V, CL = 50 pF), making it suitable for low-power logic buffering and signal inversion in industrial control panels.
For engineers reviewing the MC14069UBDG datasheet, pinout, applications, or equivalent options, key selection criteria include its wide supply range, triple diode input protection, JEDEC UB compliance, Pb-free SOIC-14 packaging, and compatibility with TTL load driving requirements.
Technical Context
The MC14069UBDG implements six identical CMOS inverter stages, each with high-impedance inputs and rail-to-rail output swing. Its design minimizes propagation delay through single-stage architecture and leverages complementary MOSFET pairs for low quiescent current (≤1.0 µA at 25°C, VDD = 15 V) and high noise immunity.
Input protection includes triple diode clamping per pin, and unused inputs must be tied to VSS or VDD to prevent floating states. The device meets JEDEC UB specifications and supports AEC-Q100-compliant variants via NLV prefix, though MC14069UBDG itself is industrial-grade.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 VDC to 18.0 VDC - enables operation across battery-powered, industrial, and legacy 5/12/15 V systems without level-shifting. |
| Propagation Delay (tPLH/tPHL) | 30 ns max at VDD = 15 V, CL = 50 pF - ensures timing-critical signal inversion with predictable latency in clock distribution or enable paths. |
| Output Drive Capability | Sinks up to 8.8 mA / sources up to −4.2 mA at VDD = 15 V - directly drives two low-power TTL loads or one low-power Schottky TTL load over full temperature range. |
| Input Protection | Triple diode clamping on all inputs - prevents ESD-induced latch-up and transient damage in noisy industrial environments. |
| Quiescent Current (IDD) | 1.0 µA max at VDD = 15 V, TA = 125°C - sustains ultra-low standby power in always-on monitoring circuits. |
| Operating Temperature | −55°C to +125°C - qualified for under-hood automotive ancillaries, motor drive control logic, and harsh-environment PLC modules. |
Pinout & Package
MC14069UBDG is housed in a 14-pin SOIC-14 (Case 751A) package with standard 1.27 mm pitch, 8.55–8.75 mm body width, and Pb-free finish. Pin 1 is index-marked; Pin 7 = VSS (GND); Pin 14 = VDD (supply).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN 1 | Input of first inverter stage - high-impedance CMOS node requiring explicit tie-high or tie-low if unused. |
| 2 | OUT 1 | Inverted output of first stage - rail-to-rail swing (VOL ≤ 0.05 V, VOH ≥ 14.95 V at VDD = 15 V) compatible with TTL thresholds. |
| 3 | IN 2 | Input of second inverter stage - electrically isolated from other inputs; shares no internal coupling. |
| 4 | OUT 2 | Inverted output of second stage - independently buffered; capable of driving capacitive loads up to 50 pF within spec. |
| 5 | IN 3 | Input of third inverter stage - protected by triple diode clamp; withstands −0.5 V to VDD + 0.5 V transient excursions. |
| 6 | OUT 3 | Inverted output of third stage - matches electrical characteristics of OUT1/OUT2; supports parallel fan-out. |
| 7 | VSS | Ground reference for all logic and substrate - must be low-impedance connection to minimize ground bounce in multi-gate switching. |
| 8 | OUT 4 | Inverted output of fourth stage - identical AC/DC specs to other outputs; usable as buffer or phase-inversion node. |
| 9 | IN 4 | Input of fourth inverter stage - same input capacitance (Cin = 7.5 pF max) and voltage thresholds (VIL/VIH) as IN1–IN3. |
| 10 | OUT 5 | Inverted output of fifth stage - supports dynamic current (IOL/IOH) matching full-load TTL interface requirements. |
| 11 | IN 5 | Input of fifth inverter stage - immune to noise spikes due to high input threshold ratio (VIH/VIL ≈ 4× at VDD = 5 V). |
| 12 | OUT 6 | Inverted output of sixth stage - final gate in array; electrically identical to others; no shared internal nodes. |
| 13 | IN 6 | Input of sixth inverter stage - requires external termination if unused; floating state risks increased IDD and instability. |
| 14 | VDD | Positive supply rail - decoupling capacitor (≥0.1 µF ceramic) required within 10 mm for stable high-speed operation. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 3.0–18.0 VDC operation allows direct integration into mixed-voltage systems (e.g., 3.3 V microcontroller I/O interfacing with 12 V sensor conditioning). |
| Single-Stage Inverter Architecture | Minimizes propagation delay variation across temperature and voltage - critical for synchronous logic timing budgets in real-time controllers. |
| Pb-Free SOIC-14 Packaging | RoHS-compliant lead finish and JEDEC-standard footprint enable drop-in replacement in legacy PCBs without requalification. |
| Triple Diode Input Protection | Provides robust ESD immunity (per human-body model) and transient suppression - reduces need for external TVS diodes in field-deployed equipment. |
| Pin-for-Pin Compatibility with CD4069UB | Enables seamless migration from legacy CD4000-series designs without layout changes or firmware updates. |
Applications
| Industrial PLC I/O Conditioning | Automotive Body Control Module Logic |

Equivalent & Alternatives
The following parts are listed as comparable options for similar hex inverter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4069UBM96 | Same pinout and function but wider propagation delay (160 ns typical at 5 V), higher quiescent current (5 µA), and narrower supply range (3–15 V). | Not rated for 125°C operation; unsuitable for under-hood automotive or high-temp industrial use. | Select only for cost-sensitive, room-temperature legacy replacements where timing slack exists. |
| 74HC04DR | Higher speed (19 ns max at 4.5 V), lower VDD range (2–6 V), and no triple-diode input protection. | Requires level-shifting for >6 V systems; lacks robustness in electrically noisy environments. | Prefer for high-speed 3.3/5 V digital systems; avoid in mixed-voltage or ESD-prone industrial settings. |
Compared with CD4069UBM96 and 74HC04DR, MC14069UBDG uniquely balances wide supply tolerance (3–18 V), high-temperature operation (−55°C to +125°C), and integrated input protection - making it the optimal choice for ruggedized, multi-rail, and long-lifecycle embedded systems.

FAQ
What is the maximum operating temperature for MC14069UBDG?
The MC14069UBDG is rated for an ambient temperature range of −55°C to +125°C, verified per its Maximum Ratings table and supported by electrical characterization data across that full span. This makes MC14069UBDG suitable for under-hood automotive modules, motor drive control boards, and outdoor industrial enclosures where thermal extremes occur.
Does MC14069UBDG require external pull-up or pull-down resistors on unused inputs?
Yes - unused inputs on MC14069UBDG must be explicitly tied to either VSS or VDD. Leaving them floating can cause elevated quiescent current, erratic output behavior, or localized heating due to partial conduction in the CMOS pair. The datasheet mandates this practice to ensure stable operation and reliability of MC14069UBDG in production systems.
Is MC14069UBDG pin-compatible with CD4069UB?
Yes - MC14069UBDG is explicitly specified as a pin-for-pin replacement for CD4069UB, sharing identical SOIC-14 pinout, logic function, and DC electrical characteristics. This compatibility is confirmed in the "Features" section of the onsemi datasheet and validated across supply voltages from 3.0 V to 18.0 V, making MC14069UBDG a direct upgrade path.
What load types can MC14069UBDG drive directly?
MC14069UBDG is characterized to drive two low-power TTL loads or one low-power Schottky TTL load across its full rated temperature range (−55°C to +125°C). Its output drive strength (up to 8.8 mA sink at VDD = 15 V) supports direct interfacing with 74LS, 74ALS, and similar families without external buffers - a key capability documented in the "Features" and "Electrical Characteristics" sections for MC14069UBDG.
How does the triple diode protection on MC14069UBDG inputs improve system robustness?
The triple diode protection on each MC14069UBDG input provides enhanced ESD immunity and transient voltage clamping, limiting input excursions to −0.5 V to VDD + 0.5 V. This design prevents latch-up and gate oxide damage during handling or field operation - reducing failure rates in industrial environments where cable disconnection events or inductive kickback may occur near MC14069UBDG signal lines.
