Product details
Overview
MC14071BDTG from onsemi is a quad 2-input OR gate CMOS logic IC designed for low-power, high-noise-immunity digital signal combining in industrial control, instrumentation, and power management systems. It operates across 3.0–18.0 VDC supply, delivers ±10 mA output drive per pin, and features buffered outputs capable of driving two low-power TTL loads over −55°C to +125°C.
For engineers reviewing the MC14071BDTG datasheet, pinout, applications, or equivalent options, this device serves as a direct functional replacement for CD4071B in wide-supply-voltage legacy and ruggedized embedded designs where input clamping, ESD robustness (>3 kV HBM), and rail-to-rail logic swing are critical.
Technical Context
The MC14071BDTG implements four independent non-inverting OR gates using complementary P- and N-channel enhancement-mode MOSFETs in a monolithic CMOS structure. Each gate exhibits rail-to-rail output swing (VOH ≥ VDD − 0.05 V, VOL ≤ 0.05 V at VDD = 5/10/15 V) and guaranteed DC noise margins of 1.0 V (5 V), 2.0 V (10 V), and 2.5 V (15 V).
Input protection includes double diode clamping (except triple on NAND/AND variants), and unused inputs must be tied to VSS (for OR/NOR) or VDD (for AND/NAND) to prevent floating-node instability. Quiescent current remains below 30 µA per package at 25°C and 15 VDD.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input OR gate - enables parallel signal aggregation without inversion, e.g., fault-or-alarm summation. |
| Supply Voltage Range | 3.0 VDC to 18.0 VDC - supports single-supply operation across battery, industrial, and automotive auxiliary rails. |
| Output Drive Capability | ±10 mA per pin - sufficient to directly interface with legacy TTL, CMOS, and microcontroller GPIOs without buffering. |
| Input Voltage Thresholds | VIL ≤ 4.0 V, VIH ≥ 11 V at VDD = 15 V - ensures reliable switching with wide hysteresis margin under noisy conditions. |
| Propagation Delay | 40–200 ns (CL = 50 pF, VDD = 15–5 V) - predictable timing for synchronous combinatorial logic in sub-MHz control paths. |
| ESD Withstand | >3000 V HBM - meets IEC 61000-4-2 Level 3 requirements for board-level handling and field reliability. |
| Operating Temperature | −55°C to +125°C - qualified for extended-temperature industrial, aerospace, and under-hood automotive subsystems. |
Pinout & Package
TSSOP-14 (Case 948G) package: 4.9 mm × 4.4 mm × 1.2 mm body, 0.65 mm pitch, Pb-free, RoHS-compliant, with exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 5, 6, 8, 9, 10, 11, 12, 13 | Input or Output | Pins 1/2 = Gate A inputs; 3 = Gate A output; 5/6 = Gate B inputs; 4 = Gate B output; 8/9 = Gate C inputs; 10 = Gate C output; 12/13 = Gate D inputs; 11 = Gate D output. |
| 7 | VSS | Ground reference for all gates - must be low-impedance connection to minimize ground bounce in multi-gate switching. |
| 14 | VDD | Positive supply rail - requires local 100 nF ceramic decoupling within 5 mm of pin to suppress supply transients during output transitions. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | VOH ≥ VDD − 0.05 V and VOL ≤ 0.05 V across full VDD and temperature range - eliminates level-shifting in mixed-voltage systems. |
| Wide supply voltage tolerance | 3.0–18.0 VDC operation - allows reuse across 3.3 V, 5 V, 12 V, and 15 V subsystems without redesign. |
| High DC noise immunity | Guaranteed 2.5 V noise margin at 15 VDD - prevents false triggering in electrically noisy motor-control or power-conversion environments. |
| Low quiescent current | ≤30 µA total package IDD at 25°C and 15 V - enables always-on monitoring circuits with multi-year battery life. |
| Pb-free & RoHS-compliant | TSSOP-14 package with "G" suffix - satisfies global environmental compliance and lead-free reflow process requirements (JEDEC J-STD-020). |
Applications
| Industrial Control Logic | Power Sequencing Monitor |
|---|---|
Use Scenario: Combining multiple sensor fault signals (e.g., overtemperature, overcurrent, fan failure) into a single system-alert line. IC Role / Device Role / Timing Role: OR gate performing wired-OR summation of asynchronous digital fault flags with no propagation delay skew between channels. Use Value: Eliminates need for discrete diodes or microcontroller polling, reducing BOM count and firmware complexity while maintaining deterministic response. |
Use Scenario: Validating that all required power rails (e.g., 12 V, 5 V, 3.3 V) have stabilized before enabling downstream FPGA or processor. IC Role / Device Role / Timing Role: Final-stage OR gate aggregating individual rail-good signals to generate a global "power-ok" enable pulse. Use Value: Ensures fail-safe startup sequencing with hardware-level redundancy - no software dependency or boot-time race conditions. |
| Automotive Body Electronics | Legacy System Interface Adapter |
Use Scenario: Merging door-open, trunk-open, and hood-open status signals for centralized vehicle security module. IC Role / Device Role / Timing Role: High-temperature-stable OR function operating directly from 12 V battery rail with ESD-hardened inputs. Use Value: Meets AEC-Q100 stress test requirements without external protection, simplifying layout and passing EMC testing per ISO 11452-2. |
Use Scenario: Bridging 5 V TTL logic outputs from legacy PLC modules to 3.3 V microcontroller inputs in retrofit industrial controllers. IC Role / Device Role / Timing Role: Level-translating OR gate leveraging wide VDD range to accept 5 V inputs and drive 3.3 V–compatible outputs. Use Value: Avoids dedicated level shifters; enables drop-in integration of older equipment into modern low-voltage control architectures. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4071BE | Same logic function and pinout, but narrower 3–15 V supply range and lower ESD rating (1.5 kV HBM). | Not qualified for automotive or extended-temp industrial use; lacks AEC-Q100 validation. | Select when cost is primary and operating temperature stays within −40°C to +85°C with clean power rails. |
| MC14071BDG | Identical electrical specs and logic behavior; differs only in SOIC-14 (Case 751A) packaging vs. TSSOP-14. | SOIC offers easier hand-soldering and higher thermal mass; TSSOP saves PCB area and suits automated assembly. | Choose MC14071BDG for prototyping or through-hole compatibility; MC14071BDTG for space-constrained production boards. |
Compared with CD4071BE and MC14071BDG, the MC14071BDTG provides identical logic functionality with superior high-temperature operation (−55°C to +125°C), higher ESD robustness, and a smaller footprint - making it optimal for thermally demanding, miniaturized, or automotive-grade deployments.

FAQ
What is the maximum supply voltage rating for MC14071BDTG?
The MC14071BDTG has an absolute maximum DC supply voltage (VDD) rating of +18.0 V, with a recommended operating range of 3.0 V to 18.0 V. Exceeding 18.0 V risks permanent damage per the Absolute Maximum Ratings table in the official datasheet. The MC14071BDTG maintains full logic functionality and specified timing across this entire range.
Does MC14071BDTG support direct connection to TTL logic families?
Yes, the MC14071BDTG is explicitly rated to drive two low-power TTL loads or one low-power Schottky TTL load over its full temperature range. Its output drive strength (±10 mA per pin) and rail-aligned VOH/VOL levels ensure compatible interfacing with 74LS, 74L, and other standard TTL families without external pull-ups or buffers.
How should unused inputs be handled on MC14071BDTG?
All unused inputs on the MC14071BDTG must be tied to VSS (ground), as specified in the datasheet's "Device Description" section. This prevents floating inputs from causing excessive supply current, oscillation, or unpredictable output states - especially critical given the OR gate's non-inverting nature and high-impedance CMOS inputs.
Is MC14071BDTG pin-compatible with CD4071B devices?
Yes, the MC14071BDTG is a pin-for-pin replacement for CD4071B-series devices, including CD4071BE and CD4071BM. Both share identical TSSOP-14 (or SOIC-14) pin assignments, logic function, and truth table behavior - enabling drop-in upgrades with improved supply range, noise margin, and temperature capability.
What is the thermal performance of MC14071BDTG in TSSOP-14 package?
The MC14071BDTG in TSSOP-14 (Case 948G) has a junction-to-ambient thermal resistance (θJA) of approximately 150°C/W under standard JEDEC PCB conditions. At maximum rated power dissipation (500 mW), this limits safe continuous operation to ambient temperatures below ~40°C unless heatsinking or airflow is added - consistent with typical low-power CMOS logic usage.
