Product details
Overview
74LVC2G86GM,125 from Nexperia is a dual 2-input XOR gate logic IC with Schmitt-trigger inputs, IOFF partial power-down capability, and 1.65 V to 5.5 V supply operation. It supports mixed-voltage translation between 3.3 V and 5 V systems, delivers ±24 mA output drive at 3.0 V, and operates across –40 °C to +125 °C. Used in level-shifting interfaces for industrial control I/O expansion.
For engineers reviewing the 74LVC2G86GM,125 datasheet, 74LVC2G86GM,125 pinout, 74LVC2G86GM,125 application, or 74LVC2G86GM,125 equivalent, key selection criteria include its dual XOR function with IOFF protection, Schmitt-trigger noise immunity, wide VCC range, and XQFN8 (SOT902-2) package compatibility with high-density PCB layouts.
Technical Context
This device implements two independent CMOS XOR gates with identical truth tables (L/L→L, L/H→H, H/L→H, H/H→L). Each gate features Schmitt-trigger inputs enabling robust operation with slow-rising signals and high noise immunity in noisy industrial environments.
The IOFF circuit actively disables outputs during power-down, blocking backflow current when VCC = 0 V - critical for hot-swap and partial-power-down system architectures. Input overvoltage tolerance up to 5.5 V allows safe interfacing with 5 V logic while powered from 1.65–3.3 V rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct interface with both 1.8 V, 2.5 V, 3.3 V, and 5 V logic families without level shifters. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - sufficient to drive multiple standard CMOS/TTL loads or moderate capacitive bus lines. |
| Propagation Delay | 0.8 ns (min) to 4.5 ns (max) at VCC = 4.5–5.5 V - supports >200 MHz toggle rates in high-speed digital control paths. |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - ensures negligible current flow during power sequencing or standby, preventing bus contention. |
| Input Thresholds | VIL ≤ 0.3VCC, VIH ≥ 0.7VCC - provides rail-to-rail input compatibility and predictable switching across full VCC range. |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets industrial-grade ESD robustness requirements per JS-001/JS-002 standards. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive modules, motor drives, and industrial PLC I/O stages. |
Pinout & Package
XQFN8 package (SOT902-2): plastic ultra-thin quad flat no-lead; 8 terminals; body size 1.4 × 1.2 × 0.5 mm; wettable flank leads for automated optical inspection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A | Gate A/B input A | Primary data input for XOR Gate 1 or Gate 2; accepts 0–5.5 V regardless of VCC. |
| 1B, 2B | Gate A/B input B | Secondary data input for XOR Gate 1 or Gate 2; Schmitt-triggered for noise rejection. |
| 1Y, 2Y | Gate A/B output | CMOS push-pull output; active-drive and active-pull; IOFF disables both states when VCC = 0. |
| GND | Ground reference | 0 V return path for all internal logic and output drivers; must be low-impedance for signal integrity. |
| VCC | Supply voltage | Primary power rail (1.65–5.5 V); powers both gates and IOFF control circuitry. |
Key Features
| Feature | Design Value |
|---|---|
| Dual independent XOR gates | Two fully isolated logic functions in one die - reduces board space vs. discrete gates and simplifies routing. |
| Schmitt-trigger inputs | Input hysteresis ≥ 0.3 V at VCC = 3.3 V - rejects noise on slow edges (e.g., mechanical switch debouncing, sensor outputs). |
| IOFF partial power-down | Outputs go high-impedance when VCC = 0 V - prevents backfeeding into powered subsystems during hot-plug or sleep modes. |
| Overvoltage-tolerant inputs | Inputs withstand 5.5 V regardless of VCC setting - enables 5 V signal reception while operating at 1.8 V or 2.5 V. |
| JEDEC-compliant voltage ranges | Validated per JESD8-7 (1.65–1.95 V), JESD8-5 (2.3–2.7 V), JESD8C (2.7–3.6 V), JESD36 (4.5–5.5 V) - guarantees interoperability across legacy and modern logic families. |
Applications
| Industrial I/O Expansion | Motor Control Feedback |
|---|---|
|
Use Scenario: Adding isolated digital input channels to PLC base units using mixed-voltage field sensors (5 V encoders, 3.3 V limit switches). IC Role / Device Role / Timing Role: Level-translating XOR gate performing parity validation and signal conditioning before FPGA/CPU sampling. Use Value: Eliminates external level shifters; Schmitt inputs suppress EMI-induced glitches on long cable runs. |

IC Role / Device Role / Timing Role: Real-time XOR comparator generating direction pulse stream synchronized to encoder clock edge. Use Value: Sub-5 ns propagation delay ensures accurate direction detection at >100 kRPM; IOFF prevents encoder line contention during controller reset. |
| USB-C Power Delivery Logic | Secure Boot Signal Integrity |
|
Use Scenario: Validating CC line state transitions during USB-C port negotiation where 5 V CC signaling occurs alongside 3.3 V MCU logic. IC Role / Device Role / Timing Role: Dual XOR used as controlled inverter and status comparator for CC1/CC2 line arbitration logic. Use Value: Overvoltage-tolerant inputs accept 5 V CC signals directly; wide VCC range matches MCU supply without additional regulators. |
Use Scenario: Generating tamper-detect signatures by XORing redundant boot strap pins in secure microcontroller initialization sequences. IC Role / Device Role / Timing Role: Hardware-based XOR combiner producing deterministic signature bits prior to cryptographic verification. Use Value: Low ICC (<4 μA) minimizes static power impact on battery-backed security modules; –40 °C to +125 °C rating ensures reliability in extended temperature deployments. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G86DBVR | Same logic function and IOFF, but in SOT-23-8 (SOT23-8) package; 2.9 × 2.8 × 1.45 mm body; higher thermal resistance (θJA = 278 °C/W). | Less suitable for ultra-dense layouts; requires larger pad clearance; lower max ambient due to thermal limits. | Select when board assembly uses legacy SOT-23 tooling and thermal budget permits. |
| 74AUP2G86GS,132 | Ultra-low-power variant (ICC < 0.9 μA typ); same XSON8 (SOT1203) footprint; reduced drive (±4 mA at 3.0 V); slower tpd (max 11.3 ns at 3.3 V). | Better for always-on sensor nodes; insufficient for driving >15 pF loads or >10 MHz clocks. | Select only when sub-μA static current is mandatory and speed/load requirements are relaxed. |
Compared with SN74LVC2G86DBVR, 74LVC2G86GM,125 offers 40% smaller footprint and 3× better thermal performance; versus 74AUP2G86GS,132, it trades 2.7× higher ICC for 2.4× faster propagation and 6× stronger drive - making it optimal for timing-critical industrial interfaces.

FAQ
Does 74LVC2G86GM,125 support true bidirectional level shifting?
No - it is a unidirectional logic gate with overvoltage-tolerant inputs, not a dedicated level shifter. Inputs accept 0–5.5 V regardless of VCC, but outputs swing only between GND and VCC. For true bidirectional translation (e.g., I²C), a dedicated bus switch or auto-directional translator is required.
Can the IOFF feature be used with VCC = 1.65 V and inputs at 5 V?
Yes - IOFF activates only when VCC = 0 V. At VCC = 1.65 V, the device operates normally: inputs tolerate 5 V, outputs swing 0–1.65 V, and IOFF remains inactive. IOFF is not a voltage-level detector; it responds solely to VCC absence.
What is the maximum capacitive load this device can drive reliably at 10 MHz?
At VCC = 3.3 V and 10 MHz toggle rate, CPD = 15.8 pF/gate implies ~0.17 mW dynamic power per gate. With ±24 mA drive, it can reliably drive ≤30 pF loads (including trace + probe capacitance) while maintaining <1 ns skew and <5% overshoot per Nexperia's recommended test conditions.
Is the XQFN8 (SOT902-2) package RoHS and REACH compliant?
Yes - Nexperia confirms full compliance with EU RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006 for the 74LVC2G86GM,125 in SOT902-2 packaging, including lead-free terminations and halogen-free molding compound, with full material declarations available upon request.
