Product details
Overview
MC14069UBFELG 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, noise-immune control interfaces, and legacy industrial logic systems requiring high noise immunity and minimal quiescent current.
For engineers reviewing the MC14069UBFELG datasheet, pinout, applications, or equivalent options, this page provides verified package mapping (SOEIAJ-14), confirmed electrical parameters at 5/10/15 VDD, propagation delay values (30–125 ns), output drive capability (±0.36–8.8 mA), and direct functional alternatives for legacy design continuity.
Technical Context
The MC14069UBFELG implements six identical single-stage CMOS inverters with complementary MOSFET pairs per gate, enabling rail-to-rail output swing and symmetrical rise/fall times. Its input stage includes triple diode protection for ESD robustness, and unused inputs must be tied to VSS or VDD to prevent floating node instability.
Propagation delay scales linearly with load capacitance (e.g., tPHL = 0.26 ns/pF × CL + 17 ns at VDD = 15 V), and total supply current combines dynamic (frequency-dependent) and quiescent components (IDD/6 per gate). The device meets JEDEC UB specifications and is Pb-free/RoHS compliant.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 3.0 VDC to 18.0 VDC - Enables operation across wide-battery and industrial supply rails without level-shifting. |
| Operating Temperature | −55 °C to +125 °C - Qualified for extended industrial and under-hood automotive environments. |
| Propagation Delay (CL = 50 pF) | 30 ns (VDD = 15 V) - Supports reliable timing in medium-speed digital control loops up to ~10 MHz. |
| Output Drive (Sink/Source) | ±0.36 mA to ±8.8 mA - Sufficient to directly drive two LSTTL loads or one LS Schottky TTL load. |
| Quiescent Current (Per Package) | 0.0005 A at 5 V, 0.0015 A at 15 V - Enables ultra-low standby power in always-on sensor nodes. |
| Input Capacitance | 5.0–7.5 pF - Minimizes capacitive loading on preceding stages in cascaded logic networks. |
| Input Protection | Triple diode clamping on all inputs - Provides robustness against ±10 mA transient overcurrent per pin. |

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, identical logic function, but rated only to +85 °C and lacks triple diode protection. | Not suitable for extended temperature or high-ESD environments; requires external clamping for robustness. | Select when cost is primary constraint and operating temperature remains ≤85 °C. |
| 74HC04DR | Higher speed (11 ns @ 5 V), narrower supply range (2–6 V), and no extended temperature rating. | Requires level-shifting for 12/15 V systems; unsuitable for industrial or automotive ambient conditions. | Select only for 5 V-only, high-speed digital systems where temperature stays below +70 °C. |
Compared with MC14069UBFELG, CD4069UBM96 offers lower cost but reduced ruggedness and temperature range, while 74HC04DR delivers faster switching at the expense of voltage flexibility and environmental qualification - making MC14069UBFELG the sole choice for wide-supply, high-noise, extended-temperature legacy upgrades.

FAQ
Is MC14069UBFELG still in active production?
No, MC14069UBFELG is marked as discontinued by onsemi per the August 2025 datasheet revision. However, Aetrix Electronics maintains strategic inventory and supports last-time buys, cross-referencing, and obsolescence mitigation for legacy designs dependent on this part.
What is the package type and lead count of MC14069UBFELG?
MC14069UBFELG uses the SOEIAJ-14 package (Case 965), a 14-lead surface-mount gull-wing package with 1.27 mm pitch and Pb-free finish. Its dimensions are 9.90–10.50 mm × 5.10–5.45 mm × 1.42 mm max height.
Can MC14069UBFELG replace CD4069UB in an existing design?
Yes, MC14069UBFELG is explicitly specified as a pin-for-pin replacement for CD4069UB, with identical pinout, logic function, and JEDEC UB compliance - enabling direct substitution without PCB or firmware changes.
What is the maximum output drive capability of MC14069UBFELG at 15 V supply?
At VDD = 15 V, MC14069UBFELG delivers up to 8.8 mA sink current (IOL) and −8.8 mA source current (IOH), sufficient to drive one low-power Schottky TTL load or two standard low-power TTL loads across the full −55 °C to +125 °C range.
Does MC14069UBFELG require external pull-up or pull-down resistors on unused inputs?
Yes - unused inputs on MC14069UBFELG must be tied directly to either VSS or VDD. Leaving them floating risks increased supply current, erratic switching, and potential device damage due to undefined CMOS gate states.
