Product details
Overview
MC74LVX86DR2 from onsemi is a quad 2-input XOR gate in SOIC-14 package, designed for level-shifting logic interfaces between 3.0 V and 5.0 V systems. It delivers 5.8 ns typical propagation delay at 3.3 V, supports 5 V-tolerant inputs up to 6.5 V, and operates across −40°C to +85°C with <2 µA quiescent current.
For engineers reviewing the MC74LVX86DR2 datasheet, pinout, applications, or equivalent options, key selection criteria include input voltage tolerance, propagation delay matching across gates, output drive capability (±25 mA), and compatibility with LVX-family logic families in mixed-voltage digital systems.
Technical Context
The MC74LVX86DR2 implements four independent CMOS XOR gates with balanced tPLH/tPHL delays and low output skew (<1.5 ns). Its 5 V-tolerant inputs use internal clamping diodes and enable direct connection to legacy 5 V buses without external level shifters.
All gates share a common VCC (Pin 14) and GND (Pin 7) supply, with no internal power-down control-power-down protection is achieved via input diode current limiting (±20 mA) and guaranteed latchup immunity (>300 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 2.0 V to 3.6 V - Enables operation in 2.5 V/3.3 V systems while maintaining full 5 V input tolerance. |
| Input Voltage Tolerance | −0.5 V to +6.5 V - Allows safe interfacing with 5 V TTL/CMOS signals without external protection. |
| tPD (Typ) | 5.8 ns at VCC = 3.3 V, CL = 15 pF - Ensures timing-critical XOR functions (e.g., parity generation, error detection) meet sub-6 ns budget. |
| IOL/IOH | ±25 mA per output - Supports driving standard 50 Ω transmission lines or fan-out to ≥10 LS-TTL loads. |
| ICC (Max) | 2.0 µA at TA = 25°C - Minimizes standby power in battery-backed or always-on logic subsystems. |
| Operating Temp | −40°C to +85°C - Qualified for industrial-grade embedded control and communications equipment. |
| ESD HBM | >2000 V - Meets IEC 61000-4-2 Level 2 for robust handling in manufacturing and field service. |
Pinout & Package
MC74LVX86DR2 is packaged in SOIC-14 NB (Case 751A), 8.75 mm × 4.00 mm body, 1.27 mm pitch, with gull-wing leads and Pb-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 10, 13 | A0–A3 (Data Input A) | First input of each XOR gate; 5 V-tolerant, accepts 0–6.5 V swing. |
| 2, 5, 12, 9 | B0–B3 (Data Input B) | Second input of each XOR gate; identical voltage tolerance and loading as A inputs. |
| 3, 6, 11, 8 | O0–O3 (Output) | CMOS push-pull outputs; rail-to-rail swing, ±25 mA drive, low noise (VOLP ≤ 0.5 V). |
| 7 | GND | Ground reference for all logic and power paths; must be low-impedance for noise control. |
| 14 | VCC | Positive supply (2.0–3.6 V); powers all four gates; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| 5 V–Tolerant Inputs | Enables direct connection to 5 V microcontrollers, FPGAs, or legacy peripherals without external level translators. |
| Balanced Propagation Delays | Ensures consistent timing across all four XOR gates-critical for synchronous parity checking and data path alignment. |
| Low Dynamic Output Noise | VOLP ≤ 0.5 V (typ 0.3 V) minimizes crosstalk in dense PCB layouts with adjacent high-speed signals. |
| Latchup Immunity | Exceeds 300 mA - Guarantees robustness against transient overvoltage events in noisy industrial environments. |
| Pb-Free & RoHS Compliant | Meets global environmental regulations; compatible with lead-free reflow profiles (J-STD-020, peak 260°C). |
Applications
| Parity Generation | Error Detection in Serial Links |
|---|---|
|
Use Scenario: Generating even/odd parity bits for 4-bit data words in UART or SPI peripheral interfaces. IC Role / Device Role / Timing Role: Performs bitwise XOR across parallel data lanes with deterministic 5.8 ns delay per bit. Use Value: Enables real-time parity calculation without pipeline stalls; low ICC supports always-on monitoring in low-power modes. |
Use Scenario: Detecting bit-flip errors in RS-485 or CAN FD transceiver receive paths using checksum comparison. IC Role / Device Role / Timing Role: Compares transmitted vs. received nibbles; output toggles only on mismatch. Use Value: Sub-6 ns response ensures error flag assertion meets tight timing budgets in deterministic industrial networks. |
| Address Decoding | Programmable Logic Glue |
|
Use Scenario: Selecting memory-mapped peripherals in 3.3 V microcontroller systems interfacing with 5 V address latches. IC Role / Device Role / Timing Role: Combines chip-select and address bits to generate unique decode signals. Use Value: 5 V-tolerant inputs eliminate level-shifter ICs, reducing BOM count and board area in space-constrained designs. |
Use Scenario: Implementing custom combinational logic (e.g., state machine enable conditions) in FPGA-adjacent control planes. IC Role / Device Role / Timing Role: Provides fast, predictable XOR function for glue logic where programmable resources are constrained. Use Value: Pin-and-function compatibility with 74-series logic simplifies legacy design migration and reduces validation effort. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC86AD | Wider VCC range (1.65–5.5 V); lower tPD (4.2 ns typ); no 5 V input tolerance above VCC. | Requires external clamping for >3.6 V inputs; better suited for single-supply 3.3 V systems with strict speed needs. | Select when operating exclusively at 3.3 V and maximum speed is critical; avoid if interfacing with 5 V buses. |
| 74AHC86D | Higher VCC max (5.5 V); higher ICC (40 µA); 5 V tolerant only up to VCC + 0.5 V (not 6.5 V). | Limited 5 V interface margin; higher static power disfavors battery-powered applications. | Choose for cost-sensitive industrial controls where 5 V bus voltage stays within 5.0 V ±5% and power budget allows. |
Compared with SN74LVC86AD and 74AHC86D, the MC74LVX86DR2 uniquely combines 6.5 V input tolerance with ultra-low ICC and industrial temperature range-making it optimal for mixed-voltage systems requiring long-term reliability and minimal standby power.

FAQ
What is the maximum input voltage the MC74LVX86DR2 can tolerate?
The MC74LVX86DR2 supports DC input voltages from −0.5 V to +6.5 V regardless of VCC level-enabling direct connection to 5 V logic without external protection. This specification is validated per the Absolute Maximum Ratings table in the official onsemi datasheet (Rev. 5, May 2024), and applies to all A0–A3 and B0–B3 pins.
Does the MC74LVX86DR2 support operation at 2.5 V VCC?
Yes, the MC74LVX86DR2 is fully specified for VCC from 2.0 V to 3.6 V, including 2.5 V operation. At 2.5 V, VIH is guaranteed ≥1.5 V and VOL ≤0.1 V (IOL = 4 mA), ensuring reliable noise margins and compatibility with 2.5 V logic families-per the Recommended Operating Conditions and DC Electrical Characteristics tables.
Is the MC74LVX86DR2 pin-compatible with standard 74-series XOR gates?
Yes, the MC74LVX86DR2 uses the industry-standard SOIC-14 pinout for quad 2-input XOR gates (e.g., 74LS86, 74HC86), with identical pin assignments for inputs (A0–A3, B0–B3), outputs (O0–O3), VCC (Pin 14), and GND (Pin 7)-confirmed in the Pin Assignment diagram and Function Table of the onsemi datasheet.
What is the typical propagation delay of the MC74LVX86DR2 at 3.3 V?
The MC74LVX86DR2 achieves a typical propagation delay (tPD) of 5.8 ns at VCC = 3.3 V, CL = 15 pF, as measured per AC Electrical Characteristics (page 3 of datasheet Rev. 5). This value is consistent across all four gates and reflects the average of tPLH and tPHL under defined test conditions.
Does the MC74LVX86DR2 require external pull-up or pull-down resistors on unused inputs?
No, unused inputs on the MC74LVX86DR2 may be tied directly to VCC or GND-no external resistors needed. The device features built-in power-down protection and input leakage current ≤±1.0 µA (at Vin = 5.5 V or GND), eliminating floating-input risk and simplifying layout per the "Power Down Protection Provided on Inputs" feature statement.
