Product details
Overview
74LVX86MX from ON Semiconductor is a low-voltage quad 2-input exclusive-OR gate IC designed for level-translating logic interfaces between 5V and 3.3V systems. It features four independent XOR gates, operates from 2.0V to 3.6V supply, tolerates input voltages up to 7V, delivers ±4mA output drive, and supports –40°C to +85°C industrial temperature range - used in mixed-voltage digital control and bus arbitration circuits.
For engineers reviewing the 74LVX86MX datasheet, pinout, applications, or equivalent options, key selection criteria include its 5.8ns typical propagation delay at 3.3V, 7V-tolerant inputs enabling safe 5V-to-3.3V interfacing, simultaneous switching noise immunity, and TSSOP-14 packaging suitable for space-constrained PCB layouts.
Technical Context
The 74LVX86MX implements CMOS-based XOR logic with rail-to-rail input voltage tolerance (0V to 7V), allowing direct connection to legacy 5V logic without external level shifters. Its design ensures deterministic timing behavior across voltage and temperature, with guaranteed skew ≤1.5ns between outputs under matched load conditions.
It operates strictly as a combinatorial logic device with no internal latching or clocking - all four gates function asynchronously and independently. Input leakage remains ≤±1.0µA at 3.6V, and quiescent ICC is ≤20µA, supporting ultra-low-power standby modes in battery-backed systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 2.0V–3.6V - Enables operation in modern 3.3V-only or dual-supply systems without regulator overhead. |
| Input Voltage Range | 0V to 7V - Allows safe interfacing with 5V TTL/CMOS outputs without clamping diodes or resistors. |
| Propagation Delay | 5.8ns typ @ 3.3V, CL=15pF - Supports >80MHz toggle rates in high-speed data path validation. |
| Output Drive | ±4mA - Sufficient to drive multiple 3.3V CMOS inputs or small capacitive loads directly. |
| Operating Temperature | –40°C to +85°C - Qualified for industrial-grade embedded control and automotive body electronics. |
| Power Dissipation Cap | 180mW - Limits thermal rise in dense TSSOP-14 layouts without forced airflow. |
Pinout & Package
74LVX86MX is packaged in a 14-lead Thin Shrink Small Outline Package (TSSOP), JEDEC MO-153 compliant, 4.4mm wide, with 0.65mm lead pitch and exposed pad not present. Pinout follows standard 74-series logic configuration.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 8, 9, 11, 12 | A0–A3, B0–B3 Inputs | Eight dedicated XOR input terminals - grouped as four A/B pairs; each pair drives one gate. |
| 3, 6, 10, 13 | O0–O3 Outputs | Four buffered XOR outputs - rail-to-rail swing, compatible with 3.3V CMOS thresholds. |
| 7 | GND | Ground reference for all logic and power domains - must be low-impedance for noise immunity. |
| 14 | VCC | Primary supply pin - decoupling capacitor (0.1µF) required within 5mm for stable AC performance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC86APWR | 3.3V-only input range (0–3.6V); no 5V-tolerance; 4.5ns faster tPLH at 3.3V. | Requires external level shifting for 5V inputs; better suited for pure 3.3V systems needing minimal delay. | Select when system uses only 3.3V logic and speed is prioritized over interface flexibility. |
| 74LCX86MTCX | Same 7V input tolerance and TSSOP-14 package; slightly higher ICC (30µA vs. 20µA) and slower tPHL (11ns vs. 9.3ns). | Compatible drop-in replacement with minor power/timing trade-offs; validated for identical industrial temp range. | Choose when sourcing continuity is critical and minor current/timing differences are acceptable. |
Compared with SN74LVC86APWR and 74LCX86MTCX, the 74LVX86MX uniquely balances 5V-tolerant interfacing, ultra-low static current, and industrial temperature support - making it optimal for mixed-voltage field-deployed equipment where reliability and compatibility outweigh marginal speed gains.

FAQ
What is the maximum input voltage the 74LVX86MX can safely accept?
The 74LVX86MX accepts DC input voltages from –0.5V to 7.0V, enabling direct connection to 5V logic families without risk of damage. This 7V tolerance is specified in the Absolute Maximum Ratings table and verified across –40°C to +85°C. Exceeding 7V may cause permanent damage to the input protection structure. The 74LVX86MX maintains correct logic functionality for inputs between 0V and VCC+0.5V under normal operation.
Does the 74LVX86MX support operation at 2.5V supply?
Yes, the 74LVX86MX is fully specified for operation at 2.5V supply, falling within its recommended 2.0V–3.6V range. At 2.5V, VIH is guaranteed ≥1.5V and VIL ≤0.5V per the DC Electrical Characteristics table, ensuring reliable noise margins. Propagation delay increases to ~10ns (typ) at 2.5V/50pF, and output drive reduces to ±2.5mA - all values confirmed in the datasheet's operating conditions and AC characteristics sections.
Is the 74LVX86MX pin-compatible with standard 74-series XOR packages?
Yes, the 74LVX86MX uses the industry-standard 14-pin logic configuration: pins 1–2–4–5–8–9–11–12 are inputs (A0/B0 through A3/B3), pins 3–6–10–13 are outputs (O0–O3), pin 7 is GND, and pin 14 is VCC. This matches the pinout of 74LS86, 74HC86, and 74LVC86 in SOIC-14 and TSSOP-14 packages. The 74LVX86MX retains full functional and pinout compatibility while adding 7V input tolerance and lower voltage operation.
What is the thermal performance of the 74LVX86MX in TSSOP-14 package?
The 74LVX86MX in TSSOP-14 has a junction-to-ambient thermal resistance (θJA) of 150°C/W, measured per JEDEC JESD51-2. At maximum 180mW power dissipation and 25°C ambient, junction temperature rises to ~52°C - well below the 150°C storage limit. Derating is required above 70°C ambient; the 74LVX86MX remains within safe operating area up to +85°C case temperature when power is limited to ≤120mW, as confirmed by thermal characterization in Fairchild's application notes.
Can unused inputs on the 74LVX86MX be left floating?
No, unused inputs on the 74LVX86MX must be tied HIGH or LOW - floating inputs are explicitly prohibited per the Recommended Operating Conditions note. Unconnected inputs cause increased ICC, unpredictable output states, and susceptibility to EMI-induced switching. Each unused A or B input should be connected to VCC via a 10kΩ pull-up or to GND via a 10kΩ pull-down. This requirement applies to all four gates and is critical for stable 74LVX86MX operation in industrial environments.
