Product details
Overview
MC14069UBFEL 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 for low-power logic inversion. It operates across 3.0–18.0 VDC supply, supports −55 °C to +125 °C ambient range, and features triple diode input protection. It is used in battery-powered instrumentation, industrial control interface buffering, and noise-immune digital signal conditioning.
For engineers reviewing the MC14069UBFEL datasheet, pinout, applications, or equivalent options, key selection criteria include its wide VDD range, high-temperature operation, SOEIAJ-14 package footprint, and compatibility with legacy CD4069UB designs in space-constrained or extended-temperature systems.
Technical Context
The MC14069UBFEL implements six identical CMOS inverter stages, each with complementary MOSFETs configured as a single-stage voltage-controlled switch-no internal level-shifting or feedback networks. Its input stage includes triple diode protection (two clamping diodes plus substrate diode), enabling robust ESD tolerance without external components.
Propagation delay is load-dependent and specified at CL = 50 pF: tPLH/tPHL = 30 ns (VDD = 15 V), 40 ns (10 V), and 65 ns (5 V); rise/fall times follow tTLH/tTHL = 40 ns (15 V), 50 ns (10 V), and 100 ns (5 V). Quiescent current per package is ≤1.0 µA at 25 °C and ≤30 µA at 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 VDC to 18.0 VDC - supports direct interface with 5 V, 12 V, and 15 V logic rails without level shifters. |
| Operating Temperature | −55 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and aerospace subsystem use. |
| Input Protection | Triple diode protection on all inputs - eliminates need for external TVS or series resistors in noisy environments. |
| Output Drive (VDD = 15 V) | Sink: 8.8 mA / Source: −8.8 mA - sufficient to drive two LS-TTL loads or one Schottky TTL load over full temperature range. |
| Propagation Delay (CL = 50 pF) | 30 ns at VDD = 15 V - enables reliable operation up to ~10 MHz toggle frequency in simple gate applications. |
| Quiescent Current | ≤1.0 µA at 25 °C - enables multi-year battery life in always-on sensor nodes or standby logic circuits. |
| Input Capacitance | 7.5 pF max - minimizes capacitive loading on preceding drivers and preserves signal edge integrity. |
Pinout & Package
MC14069UBFEL is housed in a 14-lead SOEIAJ (JEDEC MS-012) surface-mount package (Case 965), 10.5 mm × 5.45 mm × 1.42 mm, with 1.27 mm pitch, Pb-free, RoHS-compliant.
| 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) | Inverted logic outputs; open-drain behavior not supported - outputs are push-pull CMOS. |
| 7 | VSS | Ground reference for all inputs/outputs; primary return path for sink current and quiescent supply. |
| 14 | VDD | Positive supply rail; decoupling capacitor (0.1 µF) required within 5 mm for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| PIN-FOR-PIN REPLACEMENT FOR CD4069UB | Direct drop-in upgrade path for legacy 4000-series designs without PCB or firmware changes. |
| JEDAC UB SPECIFICATION COMPLIANCE | Meets standardized AC/DC electrical limits and test conditions for universal interoperability across CMOS logic families. |
| LOW POWER DISSIPATION | Max 500 mW total package power - enables thermal design without heatsinks in sealed enclosures. |
| ROHS COMPLIANT & PB-FREE | Meets EU Directive 2011/65/EU and JESD204B; compatible with lead-free reflow profiles (peak 260 °C). |
| INPUT VOLTAGE RANGE | −0.5 V to VDD + 0.5 V - allows safe interfacing with overvoltage-tolerant microcontrollers or analog comparators. |
Applications
| Industrial Sensor Interface | Battery-Powered Instrumentation |
|---|---|

Use Value: Identical SOEIAJ-14 footprint and guaranteed VIL/VIH margins prevent redesign or qualification delays. |
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, but narrower VDD range (3–15 V), higher typical propagation delay (100 ns @ 5 V), no AEC-Q100 qualification. | Limited to commercial-temperature (0–70 °C) consumer or lab equipment; lacks triple-diode input protection. | Select only when cost is primary constraint and automotive/industrial temperature or ESD robustness is not required. |
| SN74HC04DR | Higher speed (19 ns @ 5 V), lower VDD range (2–6 V), TTL-compatible inputs, no high-voltage capability. | Restricted to 5 V systems; unsuitable for 12/15 V rails or extended-temperature operation beyond 85 °C. | Choose for high-frequency digital logic in modern 3.3/5 V embedded systems where voltage headroom is limited. |
Compared with CD4069UBM96 and SN74HC04DR, MC14069UBFEL uniquely combines 18 V operation, −55 °C to +125 °C range, triple-diode input protection, and pin-for-pin CD4069UB compatibility-making it the sole option for upgrading legacy high-voltage or harsh-environment designs without layout change.

FAQ
Is MC14069UBFEL still in production?
No, MC14069UBFEL is marked as discontinued by onsemi per the August 2025 datasheet revision. However, Aetrix Electronics maintains active inventory and offers lifecycle management support-including last-time buy planning and cross-reference guidance-to sustain existing designs through end-of-life transitions.
What is the package type and footprint of MC14069UBFEL?
MC14069UBFEL uses the SOEIAJ-14 (JEDEC MS-012) package, also referenced as Case 965, with 1.27 mm lead pitch, 10.5 mm × 5.45 mm body size, and gull-wing leads. Its footprint matches CD4069UB in SOEIAJ-14 and is incompatible with SOIC-14 or TSSOP-14 variants of the same device.
Does MC14069UBFEL support 3.3 V logic levels?
Yes, MC14069UBFEL operates down to 3.0 VDC and meets VIH ≥ 2.0 V and VIL ≤ 1.0 V at VDD = 3.0 V per datasheet Electrical Characteristics - making it compatible with 3.3 V microcontrollers when driven directly, though output VOH will be ~2.95 V (not 3.3 V rail).
Can unused inputs on MC14069UBFEL be left floating?
No. Unused inputs on MC14069UBFEL must be tied to either VDD or VSS to prevent oscillation, increased power consumption, or latch-up. The datasheet explicitly states: "Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD)." Floating inputs risk undefined output states and thermal instability.
What is the maximum capacitive load MC14069UBFEL can drive reliably?
MC14069UBFEL is characterized at CL = 50 pF for timing specifications, but the datasheet confirms reliable operation with loads up to 100 pF while maintaining specified propagation delay and output voltage margins. For loads >100 pF, rise/fall times increase linearly per tTLH/tTHL = (0.40 ns/pF) × CL + 20 ns (at VDD = 15 V), requiring careful signal integrity validation.
