Product details
Overview
MC14001UBCP from onsemi is a quad 2-input NOR gate CMOS logic IC designed for low-power, high-noise-immunity digital systems. It operates across 3.0–18 VDC supply, delivers ±10 mA output drive per pin, features double diode input protection, and is pin-for-pin compatible with CD4001UB. It is widely used in industrial control sequencers and battery-powered instrumentation.
For engineers reviewing the MC14001UBCP datasheet, pinout, applications, or equivalent options, key selection considerations include its wide VDD range, rail-to-rail output swing, guaranteed 125°C operation, and compatibility with legacy CD4000-series designs.
Technical Context
The MC14001UBCP implements four independent 2-input NOR gates using complementary MOS (CMOS) P- and N-channel enhancement-mode transistors on a single monolithic die. Each gate exhibits true inverting non-buffered logic behavior with symmetrical propagation delays (tPLH/tPHL) and matched rise/fall times under defined load conditions.
Its input structure includes double diode protection against ESD and transient overvoltage, and it requires unused inputs to be tied to VSS (not floating). The device supports linear applications such as oscillator circuits due to its predictable threshold characteristics and stable transfer curves across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input NOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4001BE | Same logic function and pinout, but wider package (PDIP-14), higher quiescent current (1.5 μA typ), no AEC-Q100 qualification | Not suitable for surface-mount production or automotive-grade reliability requirements | Select only for through-hole prototyping or legacy repair where SOIC footprint is unavailable |
| 74HC02N | Narrower VDD range (2–6 V), faster propagation (15 ns typ), lower drive (±4 mA), no extended temperature support | Limited to 5 V systems; unsuitable for 12/15 V industrial rails or extreme ambient conditions | Prefer for high-speed 5 V digital systems where power efficiency is secondary to speed |
Compared with CD4001BE and 74HC02N, the MC14001UBCP uniquely balances wide-voltage operation, ultra-low static power, extended temperature resilience, and surface-mount compatibility-making it optimal for modern industrial and battery-constrained designs where robustness and longevity are critical.

FAQ
What is the maximum supply voltage rating for MC14001UBCP?
The MC14001UBCP has an absolute maximum DC supply voltage (VDD) rating of +18.0 V, with a recommended operating range of 3.0 VDC to 18 VDC. Exceeding 18.0 V may cause permanent damage. This wide range allows MC14001UBCP to interface directly with 5 V, 12 V, and 15 V system rails without regulation, simplifying power architecture in multi-voltage designs.
Does MC14001UBCP require external pull-up or pull-down resistors on unused inputs?
No - MC14001UBCP does not require external pull-up or pull-down resistors on unused inputs. Per the datasheet, all unused inputs must be tied directly to either VSS (for NOR gates) or VDD (for NAND gates) to prevent floating states and undefined logic behavior. The device lacks internal weak pull-ups/pull-downs, so hard-wiring is mandatory for reliable operation.
Is MC14001UBCP pin-compatible with CD4001UB devices?
Yes - MC14001UBCP is explicitly specified as a pin-for-pin replacement for CD4001UB devices in the onsemi datasheet. Both share identical pin assignments, logic function, electrical specifications, and SOIC-14 packaging. This compatibility enables drop-in substitution in existing CD4000-series designs without PCB or firmware modifications.
What is the typical quiescent supply current of MC14001UBCP at 10 VDC and 25°C?
The typical quiescent supply current (IDD) of MC14001UBCP is 0.5 μA at VDD = 10 VDC and TA = 25°C, with a maximum of 1.0 μA across the full temperature range. This ultra-low static power consumption makes MC14001UBCP especially valuable in always-on or battery-operated systems where minimizing standby current is essential to extending operational lifetime.
Can MC14001UBCP be used in oscillator applications?
Yes - the onsemi datasheet explicitly lists "Linear and Oscillator Applications" among the key features of MC14001UBCP. Its well-defined voltage transfer characteristics, stable threshold behavior, and ability to operate as a Schmitt-trigger inverter (when configured with feedback) make MC14001UBCP suitable for constructing RC relaxation oscillators, clock generators, and timing circuits without additional active components.
