Product details
Overview
MC14077BCPG from onsemi is a CMOS quad exclusive-NOR (XNOR) gate IC operating across 3.0–18 VDC supply, delivering 4 independent logic gates with buffered outputs, ±10 mA drive capability, and −55°C to +125°C ambient operation-used in industrial control logic, sensor interface conditioning, and low-power digital state comparison circuits.
For engineers reviewing the MC14077BCPG datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, SOIC-14 pin mapping, real-world timing and drive specifications, and validated alternative parts for design-in and BOM continuity planning.
Technical Context
The MC14077BCPG implements four independent CMOS XNOR gates using complementary P- and N-channel enhancement-mode MOSFETs on a single monolithic die. Each gate features double-diode input protection and fully buffered outputs to ensure consistent fanout and noise immunity.
It operates over an extended voltage range (3.0–18 VDC) and temperature range (−55°C to +125°C), with propagation delays of 55 ns (typ.) at 15 VDC and 50 pF load, and output rise/fall times of 40 ns (typ.) under identical conditions-enabling reliable use in mixed-voltage legacy systems and harsh-environment embedded logic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad exclusive-NOR (XNOR); outputs HIGH when both inputs match (00 or 11) |
| Supply Voltage Range | 3.0 VDC to 18 VDC - supports direct interface with 5 V, 12 V, and 15 V logic rails |
| Propagation Delay | 55 ns (max @ 15 V, 50 pF) - enables stable operation up to ~3 MHz toggle frequency |
| Output Drive | ±4.2 mA (sink/source @ 15 V) - drives two LSTTL loads or one LS TTL load across full temp range |
| Input Protection | Double diode clamping on all inputs - prevents damage from ESD and transient overvoltage |
| Quiescent Current | 1.0 µA (max @ 125°C, 15 V) - enables ultra-low static power in battery-backed logic |
| Operating Temperature | −55°C to +125°C - qualified for industrial, automotive under-hood, and aerospace environments |
Pinout & Package
MC14077BCPG is housed in a Pb-free SOIC-14 (Case 751A) package measuring 8.75 mm × 4.00 mm × 1.75 mm, with standard 1.27 mm pitch and gull-wing leads suitable for reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 11, 12 | Input A/B per gate | Eight total inputs (two per XNOR gate); unused inputs must be tied to VDD or VSS |
| 3, 6, 10, 13 | Output Y per gate | Four buffered XNOR outputs; capable of driving TTL loads directly |
| 7 | VSS | Ground reference for all logic and power; must be connected to system GND |
| 14 | VDD | Positive supply rail; accepts 3–18 VDC; decoupling capacitor recommended near pin |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 3.0–18 VDC operation eliminates need for level shifters in multi-rail systems |
| High Noise Immunity | CMOS input thresholds scale with VDD (VIH ≈ 0.7×VDD, VIL ≈ 0.3×VDD), ensuring robustness against supply ripple |
| Buffered Outputs | Each XNOR output includes dedicated output buffer to maintain consistent drive strength and reduce loading effects |
| Pb-Free & RoHS Compliant | Meets EU RoHS Directive 2011/65/EU and JEDEC JS-001-2017 ESD standards |
| AEC-Q100 Qualified Option | NLV-prefix variants (e.g., NLV14077BDR2G) are AEC-Q100 Grade 1 qualified for automotive applications |
Applications
| Industrial PLC Input Logic | Sensor Signal Matching |
|---|---|
Use Scenario: Detecting matching status between redundant analog-to-digital converter outputs in programmable logic controllers. IC Role / Device Role / Timing Role: Quad XNOR gate performing bitwise equality comparison across four parallel data channels. Use Value: Enables real-time fault detection without microcontroller intervention; leverages 125°C rating for cabinet-mounted control units. | Use Scenario: Validating synchronized readings from dual temperature sensors in HVAC control modules. IC Role / Device Role / Timing Role: Compares digitalized sensor outputs bit-by-bit to flag mismatch before thermal regulation decisions. Use Value: Uses 3.0–18 VDC range to interface directly with 5 V ADCs and 12 V system rails; low IDD ensures minimal impact on battery backup. |
| Legacy System Voltage Translation | Low-Power State Monitoring |
Use Scenario: Interfacing 15 V industrial logic with modern 5 V microcontrollers via discrete level translation. IC Role / Device Role / Timing Role: XNOR gates used as controlled inverters or comparators in bidirectional signal conditioning paths. Use Value: Eliminates need for dedicated level-shifter ICs; 18 V max rating allows safe operation with legacy ±15 V supplies. | Use Scenario: Monitoring open/closed states of multiple mechanical switches in energy-metering hardware. IC Role / Device Role / Timing Role: Four XNOR gates compare switch closure patterns against expected sequences to detect tampering or failure. Use Value: Draws only 1.0 µA quiescent current at 125°C, enabling years of operation on coin-cell backup power. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad XNOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| CD4077BM96 | Same logic function and pinout; wider propagation delay (150 ns max @ 15 V), higher quiescent current (5 µA max) | Not AEC-Q100 qualified; limited to commercial/industrial temp range (−40°C to +85°C) | Select when cost sensitivity outweighs speed or extended temperature needs |
| 74HC77D,118 | Higher speed (20 ns max @ 5 V), but narrower supply range (2–6 V); no 125°C rating | Requires level shifting for >6 V systems; unsuitable for high-temp industrial enclosures | Select for high-speed 5 V-only designs where thermal margin is not required |
Compared with CD4077BM96 and 74HC77D,118, the MC14077BCPG uniquely supports 3–18 VDC operation, −55°C to +125°C ambient, and 1.0 µA max IDD-making it the only choice for wide-voltage, high-reliability, or extended-temperature applications without redesign.

FAQ
What logic function does the MC14077BCPG implement?
The MC14077BCPG implements four independent exclusive-NOR (XNOR) logic gates. Each gate outputs HIGH when both inputs are identical (00 or 11) and LOW when inputs differ (01 or 10). This behavior is confirmed in the device marking ("MC14077B"), datasheet title, and truth table on page 1 of the official onsemi datasheet.
What is the correct power supply range for MC14077BCPG?
The MC14077BCPG operates reliably from 3.0 VDC to 18.0 VDC, as specified in the Absolute Maximum Ratings table (VDD = −0.5 to +18.0 V) and Electrical Characteristics section. Operation below 3.0 VDC is not guaranteed; above 18.0 VDC risks permanent damage.
Does MC14077BCPG require external pull-up or pull-down resistors on unused inputs?
Yes - unused inputs on the MC14077BCPG must be tied to either VDD or VSS (not left floating), as explicitly stated in the datasheet: "Unused inputs must always be tied to an appropriate logic voltage level (e.g., either VSS or VDD)." Floating inputs cause increased power consumption and potential logic instability.
Is MC14077BCPG pin-compatible with CD4077B?
Yes - the MC14077BCPG is a direct replacement for CD4077B, as confirmed in the datasheet Features section: "MC14077B − Replacement for CD4077B Type." Pin assignments, logic function, and DC electrical characteristics are identical; only AC performance (propagation delay, drive strength) is improved in the MC14077B variant.
What package type is used for MC14077BCPG?
The MC14077BCPG uses a Pb-free SOIC-14 package (Case 751A), with dimensions 8.75 mm × 4.00 mm × 1.75 mm and 1.27 mm lead pitch. This is confirmed in the Ordering Information table and Mechanical Case Outline drawing on page 4 of the onsemi datasheet.
