Product details
Overview
MC74LVX86DTR2G from onsemi is a quad 2-input XOR gate IC operating at 2.0–3.6 V supply, delivering 5.8 ns typical propagation delay at 3.3 V, 5 V-tolerant inputs for mixed-voltage interfacing, and low 2 µA max quiescent current - used in digital logic level translation and parity generation circuits within industrial control and communications interface modules.
For engineers reviewing the MC74LVX86DTR2G datasheet, pinout, applications, or equivalent options, this page provides verified functional role, TSSOP-14 package mapping, AC/DC electrical specs, noise immunity data, and validated alternative options for 3.3 V logic design and voltage-level bridging tasks.
Technical Context
The MC74LVX86DTR2G implements four independent XOR logic functions using advanced CMOS technology with input structures rated to 6.5 V, enabling safe connection to 5 V signal sources while powered from 3.3 V. Its balanced tPLH/tPHL delays ensure minimal skew between outputs.
It features power-down protection on all inputs, latch-up immunity exceeding 300 mA, and ESD robustness >2000 V HBM - critical for reliable operation in noisy industrial environments and hot-plug-capable interfaces where input floating or overvoltage transients may occur.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0–3.6 V - supports standard 3.3 V systems without level shifters |
| tPD (Typ) | 5.8 ns at VCC = 3.3 V, CL = 15 pF - enables high-speed data path timing in serial interface logic |
| Input Voltage Tolerance | −0.5 to +6.5 V - allows direct interfacing with 5 V microcontrollers or legacy peripherals |
| ICC (Max) | 2 µA at TA = 25°C - ensures ultra-low static power in battery-backed or always-on logic stages |
| VOL (Max) | 0.44 V at IOL = 4 mA, VCC = 3.0 V - guarantees clean low-level output drive into standard CMOS loads |
| VOLP (Max) | 0.5 V - limits switching noise coupling to adjacent signals in dense PCB layouts |
| Operating Temp | −40°C to +85°C - qualified for extended temperature industrial and automotive under-hood applications |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A0 | First input of Gate 0 - accepts 5 V-tolerant logic signal |
| 2 | B0 | Second input of Gate 0 - paired with A0 for XOR function O0 |

| 5 | B1 | Second input of Gate 1 - supports independent XOR evaluation |
| 6 | O1 | Output of Gate 1 - matches O0 timing and drive strength |
| 7 | GND | Ground reference - must be low-impedance return for all four gates |
| 8 | O2 | Output of Gate 2 - shares same VCC/GND rails but no internal coupling |
| 9 | B3 | Second input of Gate 3 - pin 9 is B3 per Figure 1 and PIN ASSIGNMENT diagram |
| 10 | A3 | First input of Gate 3 - swapped order vs. A2/B2 due to physical layout |

Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC86APWR | Same 3.3 V VCC range, 4.5 ns tPD (typ), but only 3.6 V max input tolerance | Lacks 5 V-tolerant inputs - requires external clamping or level shifters for 5 V signal sources | Select when full 5 V input tolerance is unnecessary and faster propagation is prioritized |
| 74AHC86PW,118 | Wider VCC range (2–5.5 V), 6.5 ns tPD (typ), higher drive (±8 mA), no 5 V-tolerant input spec | Requires matching VCC to input voltage domain; not suitable for mixed-voltage interfacing | Choose for single-supply 5 V systems needing higher output current and broader voltage flexibility |
Compared with SN74LVC86APWR and 74AHC86PW,118, the MC74LVX86DTR2G uniquely combines 5 V input tolerance with 3.3 V operation and ultra-low ICC - making it the only option among the three that eliminates external level-shifting components in 3.3 V/5 V boundary applications.

FAQ
What is the maximum input voltage rating for MC74LVX86DTR2G?
The MC74LVX86DTR2G supports DC input voltages from −0.5 V to +6.5 V, enabling safe interfacing with 5 V logic sources while operating from a 3.3 V supply. This 5 V–tolerant feature is explicitly specified in the Maximum Ratings table and confirmed in the device description - no external clamping diodes are required when connecting to 5 V microcontrollers or sensors.
Does MC74LVX86DTR2G support operation at 2.5 V supply?
Yes, MC74LVX86DTR2G is fully specified for operation at VCC = 2.0 V to 3.6 V, including 2.5 V. The Recommended Operating Conditions table confirms 2.0 V minimum, and DC Electrical Characteristics (e.g., VIH, VOL) are guaranteed across this full range - making it suitable for 2.5 V FPGA I/O banks and low-power microcontroller interfaces.
Is MC74LVX86DTR2G pin-compatible with standard 74-series XOR gates?
MC74LVX86DTR2G is pin- and function-compatible with industry-standard 74LVC86 and 74HC86 in TSSOP-14 packages. The pin assignment (A0/B0/O0/A1/B1/O1/GND/O2/B2/A2/B3/A3/VCC) matches the conventional 14-pin XOR layout - verified against the Logic Diagram, PIN ASSIGNMENT diagram, and ordering information in the datasheet.
What is the thermal performance of MC74LVX86DTR2G in TSSOP-14 package?
The MC74LVX86DTR2G in TSSOP-14 (Case 948G) has a maximum power dissipation of 833 mW at TA = 25°C, with thermal resistance θJA = 150°C/W (typical). Its −40°C to +85°C operating range and low 2 µA quiescent current minimize self-heating - allowing reliable operation in sealed enclosures without forced airflow or heatsinking.
How does MC74LVX86DTR2G handle unpowered or floating inputs?
MC74LVX86DTR2G includes power-down protection on all inputs, preventing back-current flow and latch-up when VCC = 0 V or inputs float above GND. This is explicitly stated in the Features list and supported by the ±20 mA input diode current rating (IIK) - ensuring robust behavior during power sequencing, hot-swap events, or partial system resets.
