Product details
Overview
MC14069UBD from onsemi is a CMOS hex inverter IC constructed with P-channel and N-channel enhancement-mode MOSFETs in a monolithic structure, delivering six independent single-stage inverters for low-power logic inversion. It operates across 3.0–18.0 VDC supply, supports −55°C to +125°C ambient, and provides 0.05 VDC VOL and 4.95 VDC VOH at 5 VDD - ideal for battery-powered instrumentation and noise-immune industrial control interfaces.
For engineers reviewing the MC14069UBD datasheet, pinout, applications, or equivalent options, key selection criteria include its wide VDD range, triple diode input protection, JEDEC UB compliance, and compatibility with legacy CD4069UB designs in space-constrained SOIC-14 or TSSOP-14 layouts.
Technical Context
The MC14069UBD implements six independent single-stage CMOS inverter stages, each with complementary P/N-channel enhancement-mode transistors enabling rail-to-rail output swing and high noise immunity. Its input structure includes triple diode protection per pin, and it meets JEDEC UB specifications for standardized logic behavior.
Propagation delay ranges from 30 ns to 125 ns (CL = 50 pF, VDD = 5–15 V), while rise/fall times scale linearly with load capacitance - e.g., tTLH/tTHL = (0.40 ns/pF) × CL + 20 ns at 15 VDD. Quiescent current is as low as 0.5 µA per gate at 25°C, supporting ultra-low-static-power system design.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0–18.0 VDC - enables direct interface with diverse power rails including 5 V, 12 V, and 15 V systems without level-shifting. |
| Output Low Voltage (VOL) | 0.05 VDC max at 5 VDD - ensures robust logic '0' margin against noise and threshold drift in downstream CMOS inputs. |
| Output High Voltage (VOH) | 4.95 VDC min at 5 VDD - guarantees full rail-swing output compatible with 5 V TTL and CMOS logic families. |
| Propagation Delay | 30–125 ns (CL = 50 pF, VDD = 5–15 V) - supports medium-speed timing-critical functions like clock buffering and signal conditioning. |
| Input Protection | Triple diode clamping on all inputs - prevents ESD damage up to ±10 mA transient current without external components. |
| Operating Temperature | −55°C to +125°C - qualified for extended industrial and automotive under-hood environments per AEC-Q100 (NLV variant). |
| Quiescent Current | 0.5 µA typical per gate at 25°C - enables multi-gate logic functions in always-on, low-battery applications. |
Pinout & Package
MC14069UBD is available in TSSOP-14 (Case 948G) and SOIC-14 (Case 751A) packages. Both are Pb-free, RoHS-compliant surface-mount packages with 1.27 mm pitch. The TSSOP-14 variant offers reduced footprint (5.0 × 4.4 mm) versus SOIC-14 (8.7 × 4.0 mm), suitable for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 9, 11, 13 | Input (IN1–IN6) | CMOS-compatible logic inputs with triple diode protection; must be tied to VDD or VSS if unused. |
| 2, 4, 6, 10, 12, 14 | Output (OUT1–OUT6) | Push-pull CMOS outputs capable of driving two LPTTL loads; outputs left open when unused. |
| 7 | VSS | Ground reference for all logic stages; requires low-impedance connection to minimize ground bounce. |
| 14 | VDD | Positive supply rail; decoupling capacitor (0.1 µF) recommended adjacent to pin for noise suppression. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 3.0–18.0 VDC operation eliminates need for dedicated voltage regulators in mixed-rail systems. |
| PIN-FOR-PIN Replacement | Direct drop-in replacement for CD4069UB - enables legacy design upgrades without PCB revision. |
| High Noise Immunity | Input thresholds scale with VDD (VIH ≈ 0.5×VDD, VIL ≈ 0.33×VDD), maintaining noise margin across full voltage range. |
| Low Power Dissipation | 500 mW max package power rating with sub-µA quiescent current per gate - extends battery life in portable devices. |
| JEDEC UB Compliance | Meets standardized electrical and mechanical requirements for universal interoperability in industrial logic subsystems. |

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 logic function but rated only to +85°C; no triple diode input protection; higher quiescent current (1 µA/gate typical). | Limited to commercial-temperature applications; lacks ESD hardening for harsh environments. | Select only for cost-sensitive, non-industrial designs where temperature and ESD stress are negligible. |
| 74HC04DR | Narrower VDD range (2–6 V); faster propagation (15 ns typ at 5 V); no input protection diodes; not AEC-Q100 qualified. | Optimized for high-speed 5 V digital systems; unsuitable for 12 V or automotive use. | Choose when speed > 50 MHz clock distribution is required and supply is strictly regulated at 5 V. |
Compared with CD4069UBM96 and 74HC04DR, MC14069UBD uniquely combines extended temperature operation, triple-diode input protection, and 3–18 VDC flexibility - making it the only option for ruggedized, multi-voltage, long-lifecycle industrial and automotive logic interfacing.

FAQ
What is the maximum supply voltage for MC14069UBD?
The MC14069UBD supports a DC supply voltage range of −0.5 V to +18.0 V referenced to VSS. Operation above 18.0 V risks permanent damage per the Absolute Maximum Ratings table. For reliable long-term use, the recommended operating range remains 3.0 V to 18.0 VDC, with performance fully characterized at 5 V, 10 V, and 15 V in the Electrical Characteristics section of the datasheet.
Does MC14069UBD have built-in ESD protection?
Yes, MC14069UBD features triple diode protection on all inputs, as explicitly stated in the datasheet Features section. This internal clamping structure protects against electrostatic discharge events up to ±10 mA transient current per pin, eliminating the need for external TVS diodes in most industrial and automotive applications where moderate ESD stress is expected.
Is MC14069UBD pin-compatible with CD4069UB?
Yes, MC14069UBD is explicitly specified as a pin-for-pin replacement for CD4069UB in the datasheet Features section. Both devices share identical pin assignments (six inverter inputs on odd pins 1/3/5/9/11/13, outputs on even pins 2/4/6/10/12/14, VSS on pin 7, VDD on pin 14), same SOIC-14 and TSSOP-14 footprints, and compatible logic thresholds - enabling drop-in substitution without layout changes.
What is the typical propagation delay of MC14069UBD at 5 V supply?
At VDD = 5 V and CL = 50 pF, the typical propagation delay (tPLH/tPHL) of MC14069UBD is 65 ns, as listed in the Electrical Characteristics table. This value reflects average performance across temperature and process variation; minimum and maximum delays are 30 ns and 125 ns respectively, depending on VDD and temperature conditions.
Can unused inputs on MC14069UBD be left floating?
No, unused inputs on MC14069UBD must never be left floating. The datasheet explicitly states: "Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD)." Floating CMOS inputs can cause excessive current draw, oscillation, increased power consumption, and potential latch-up due to undefined gate voltages - compromising reliability and functionality.
