onsemi MC14011BCPG

Overview

MC14011BCPG from onsemi is a quad 2-input NAND gate CMOS logic IC designed for low-power, high-noise-immunity digital control and signal conditioning. It operates across a 3.0–18 VDC supply range, delivers ±10 mA output drive per pin, and features double diode input protection. It is widely used in industrial control panels, battery-powered instrumentation, and legacy automotive body electronics where wide-voltage tolerance and latch-up immunity are critical.

For engineers reviewing the MC14011BCPG datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, SOIC-14 package mapping, temperature-rated switching performance (tPLH/tPHL ≤ 200 ns at VDD = 5 V), confirmed input voltage thresholds (VIH = 3.5 V min at 5 V), and two validated alternative parts with documented functional and packaging differences.

Technical Context

The MC14011BCPG implements four independent 2-input NAND gates using complementary MOS (CMOS) P- and N-channel enhancement-mode transistors on a single monolithic die. Its logic function is non-inverting with respect to NAND truth table behavior, and all outputs are buffered to improve fan-out capability and reduce propagation delay variation under load.

It supports operation from −55 °C to +125 °C ambient, requires unused inputs tied to VSS or VDD (VDD for NAND), and incorporates built-in ESD protection exceeding 3 kV HBM. The device is Pb-free, RoHS-compliant, and pin-for-pin compatible with CD4011B-series devices.

FAQ

What is the maximum operating temperature for MC14011BCPG?

The MC14011BCPG is rated for continuous operation from −55 °C to +125 °C ambient temperature. This specification is guaranteed per the Absolute Maximum Ratings table in the official onsemi datasheet (Rev. 13, November 2025), and applies to the SOIC-14 package variant with Pb-free finish. Derating is not required below 125 °C, and the device maintains full logic functionality and parametric compliance across this full range. MC14011BCPG achieves this via monolithic CMOS construction with optimized oxide thickness and junction isolation.

Does MC14011BCPG require external pull-up resistors on its inputs?

No, MC14011BCPG does not require external pull-up resistors on its inputs. As a CMOS device, it has extremely high input impedance (>10¹² Ω), and inputs are internally protected with double diode clamps. Unused inputs must be tied to either VDD or VSS-specifically to VDD for NAND gates like MC14011BCPG-to prevent floating states and potential shoot-through current. Pull-ups are unnecessary and would degrade noise margin and increase static power.

Is MC14011BCPG pin-compatible with CD4011B-series devices?

Yes, MC14011BCPG is explicitly specified as a pin-for-pin replacement for corresponding CD4000-series B-suffix devices, including CD4011B. The pin assignments-VDD (14), VSS (7), and identical input/output mapping for all four NAND gates-are identical. However, MC14011BCPG offers superior performance: tighter propagation delay (200 ns vs. 300 ns max), lower quiescent current (0.25 µA vs. 1 µA), and guaranteed operation to +125 °C, unlike most CD4011B variants.

What is the recommended decoupling for MC14011BCPG?

The recommended decoupling for MC14011BCPG is a 0.1 µF X7R ceramic capacitor placed between VDD (pin 14) and VSS (pin 7), with physical placement within 5 mm of the IC body and low-inductance traces. This mitigates supply rail noise generated during output transitions, especially critical when driving capacitive loads >50 pF or operating near the 125 °C upper limit. A bulk 10 µF tantalum or aluminum electrolytic capacitor may be added at the board-level power entry point, but is not required per gate.

Can MC14011BCPG drive a standard LED directly?

MC14011BCPG can drive a standard 2 mA indicator LED directly only in sink configuration (LED anode to VDD, cathode to output), provided VDD ≤ 5 V and the LED forward voltage is ≤ 2.0 V. At VDD = 5 V, the output sink current is guaranteed ≥0.64 mA (min) at VOL = 0.4 V, which is insufficient for typical 5 mA LEDs. For reliable LED drive, an external NPN transistor or dedicated LED driver is recommended. MC14011BCPG is not intended as a power-output device.
