Product details
Overview
MC14023BDR2 from onsemi is a triple 3-input NAND gate CMOS logic IC designed for low-power, high-noise-immunity digital control functions in industrial and automotive systems. It operates across a 3.0–18.0 VDC supply range, delivers ±10 mA output drive per pin, and supports ambient temperatures from −55 °C to +125 °C - enabling use in battery-powered instrumentation and harsh-environment sensor interface circuits.
For engineers reviewing the MC14023BDR2 datasheet, pinout, applications, or equivalent options, key selection criteria include its triple-gate architecture, SOIC-14 package compatibility, wide-voltage rail tolerance, and AEC-Q100-qualified variants (NLV prefix) for automotive signal conditioning and discrete logic consolidation tasks.
Technical Context
The MC14023BDR2 implements three independent 3-input NAND gates using complementary MOS (CMOS) P- and N-channel enhancement-mode transistors on a single monolithic die. Each gate features buffered outputs and double-diode input protection (excluding triple-diode variants like MC14011B).
It is pin-for-pin compatible with CD4000-series B-suffix devices and shares identical switching timing behavior with other MC140xxB family members - including propagation delays of 40–200 ns (VDD = 15–5 V, CL = 50 pF) and rise/fall times scalable by load capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Triple 3-input NAND gate - provides three independent combinational logic blocks per package for compact Boolean expression implementation. |
| Supply Voltage Range | 3.0 VDC to 18.0 VDC - supports direct interface with 3.3 V, 5 V, 12 V, and 15 V system rails without level-shifting. |
| Output Drive Capability | ±10 mA per pin - sufficient to drive two low-power TTL loads or one low-power Schottky TTL load across full temperature range. |
| Input Voltage Thresholds | VIL ≤ 4.0 V, VIH ≥ 11 V at VDD = 15 V - ensures >2.5 V DC noise margin under worst-case conditions for robust noise immunity. |
| Quiescent Current | ≤1.0 µA per package at 15 V - enables ultra-low standby power in always-on monitoring circuits. |
| Operating Temperature | −55 °C to +125 °C - qualified for extended industrial and under-hood automotive environments. |
| ESD Withstand | >3000 V HBM - protects against handling damage during assembly and field service. |
Pinout & Package
MC14023BDR2 is housed in a Pb-free SOIC-14 (Case 751A) package measuring 8.75 mm × 3.90 mm × 1.75 mm, with 1.27 mm pitch and gull-wing leads suitable for reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6, 8, 9, 10, 12, 13 | Input terminals (IN1A–IN3C) | Nine dedicated inputs assigned to three 3-input NAND gates - each gate uses three consecutive pins (e.g., Pins 1/2/5 for Gate A). |
| 3, 4, 11 | Output terminals (OUTA–OUTC) | Three buffered NAND outputs - Pin 3 = OUTA, Pin 4 = OUTB, Pin 11 = OUTC - electrically isolated and capable of sourcing/sinking ±10 mA. |
| 7 | VSS (Ground) | Common reference node for all logic levels and internal substrate bias - must be connected to system ground plane. |
| 14 | VDD (Supply) | Primary power rail connection - accepts 3.0–18.0 VDC; decoupling capacitor (0.1 µF) required within 10 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 3.0–18.0 VDC operation eliminates need for separate voltage regulators in mixed-rail systems. |

Applications
| Industrial Control Logic | Automotive Sensor Interface |
|---|---|
|
Use Scenario: Discrete safety interlock verification in PLC I/O modules where three independent sensor inputs must all be asserted before enabling actuator output. IC Role / Device Role / Timing Role: Triple NAND gate performs real-time AND-logic (via NAND-NAND inversion) across three channels with sub-200 ns propagation delay. Use Value: Eliminates microcontroller polling overhead and reduces BOM count versus discrete transistor-based solutions. |
Use Scenario: Combining throttle position, coolant temperature, and intake air pressure signals to trigger engine fault indicator when all exceed thresholds simultaneously. IC Role / Device Role / Timing Role: Configured as active-low enable gate driving LED driver or CAN transceiver enable pin with 125 °C thermal rating. Use Value: Enables deterministic hardware-level fault detection independent of firmware execution cycles. |
| Low-Power Remote Monitoring | Legacy System Logic Retrofit |
|
Use Scenario: Battery-operated environmental sensor node requiring multi-condition wake-up (e.g., motion + humidity + light threshold met) before RF transmission. IC Role / Device Role / Timing Role: NAND gate array acts as ultra-low-quiescent-current combinatorial arbiter - draws ≤1 µA in sleep state. Use Value: Extends coin-cell battery life beyond 5 years by avoiding MCU wake-ups for simple Boolean checks. |
Use Scenario: Replacing obsolete CD4023BE in legacy test equipment where PCB layout cannot be modified. IC Role / Device Role / Timing Role: Pin-compatible drop-in replacement with identical SOIC-14 footprint and identical truth table behavior. Use Value: Restores production continuity without redesign, requalification, or firmware changes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar triple 3-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4023BE | Same logic function and pinout but narrower 3–15 V supply range; higher quiescent current (10 µA typical); no AEC-Q100 variant. | Limited to commercial/industrial temp range (−40 °C to +85 °C); not qualified for automotive under-hood use. | Select when cost sensitivity outweighs extended temperature or automotive qualification needs. |
| 74HC10DR | Higher speed (tPD ≈ 10 ns @ 5 V), lower VCC range (2–6 V), and CMOS-compatible but TTL-input thresholds - not directly interchangeable at 12 V. | Requires level-shifting for 12 V systems; unsuitable for wide-supply applications without external regulation. | Choose only for 5 V-only designs demanding faster switching than MC14023BDR2's 40–200 ns range. |
Compared with CD4023BE and 74HC10DR, MC14023BDR2 uniquely balances ultra-wide supply voltage support, extended temperature capability, and automotive-grade reliability - making it optimal for mixed-voltage industrial controllers and under-hood automotive subsystems where robustness trumps raw speed.

FAQ
What logic function does the MC14023BDR2 implement?
The MC14023BDR2 implements three independent 3-input NAND gates in a single SOIC-14 package. Each gate outputs the logical NAND of its three inputs - i.e., LOW only when all three inputs are HIGH. This configuration supports compact implementation of AND, OR, and invert functions via De Morgan's theorem, and is widely used in safety-critical interlocks and sensor fusion logic where deterministic hardware-level decision-making is required.
What is the maximum supply voltage rating for MC14023BDR2?
The MC14023BDR2 has an absolute maximum DC supply voltage (VDD) rating of +18.0 V, with operational specification guaranteed from 3.0 V to 18.0 V. Operation above 18.0 V risks permanent damage per the Absolute Maximum Ratings table. For reliable long-term performance, design margins should maintain VDD ≤ 17.5 V under transient conditions, especially in automotive 12 V systems with load-dump spikes.
Is MC14023BDR2 pin-compatible with CD4023BE?
Yes, MC14023BDR2 is pin-for-pin compatible with CD4023BE, sharing identical SOIC-14 pin assignments, logic truth tables, and functional behavior. However, MC14023BDR2 extends the operating voltage range to 18 V (vs. 15 V max for CD4023BE), improves noise margin, and offers AEC-Q100-qualified variants - making it a direct, enhanced replacement in legacy designs where board space and layout cannot be altered.
Does MC14023BDR2 require external pull-up or pull-down resistors on unused inputs?
Yes - all unused inputs on MC14023BDR2 must be tied to either VDD or VSS (ground) to prevent floating nodes that cause excessive current draw, oscillation, 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)." Leaving inputs unconnected violates CMOS design rules and may compromise device reliability and EMC performance in production systems.
What is the output drive capability of MC14023BDR2 at 12 V supply?
At VDD = 12 V, the MC14023BDR2 guarantees ±4.2 mA output sink/source current per pin (IOL/IOH) while maintaining VOL ≤ 1.5 V and VOH ≥ 10.5 V. This allows direct driving of LEDs (with series resistor), small relays (via buffer transistor), or multiple 74LVC-series inputs. Exceeding ±10 mA per pin - the absolute maximum rating - risks permanent damage regardless of duty cycle or thermal management.
