Product details
Overview
74LVC2G86GD,125 from Nexperia is a dual 2-input EXCLUSIVE-OR gate logic IC with Schmitt-trigger inputs, IOFF partial power-down capability, and 1.65 V to 5.5 V supply voltage range. 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 for industrial control signal routing.
For engineers reviewing the 74LVC2G86GD,125 datasheet, 74LVC2G86GD,125 pinout, 74LVC2G86GD,125 application, or 74LVC2G86GD,125 equivalent, this device serves as a robust, low-power XOR gate for level-shifting, parity generation, and digital signal comparison in space-constrained embedded interfaces.
Technical Context
This device implements two independent CMOS XOR gates with Schmitt-trigger input thresholds-enabling tolerance of slow-rising signals and noise immunity in noisy industrial environments. Each gate features symmetrical propagation delay (tpd ≤ 4.5 ns at 5.5 V) and rail-to-rail output swing.
The IOFF circuit actively disables outputs during power-down, preventing backflow current when VCC = 0 V, while overvoltage-tolerant inputs accept up to 5.5 V regardless of supply voltage-critical for safe interfacing with legacy 5 V logic in modern low-voltage systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - Enables direct operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without external level shifters. |
| Input Voltage Tolerance | Up to 5.5 V - Allows safe connection to 5 V drivers even when powered at 1.65 V–3.3 V, eliminating risk of latch-up or damage. |
| Output Drive Strength | ±24 mA at VCC = 3.0 V - Sufficient to directly drive multiple LVC/LVT inputs or small capacitive loads (<30 pF) without buffering. |
| Propagation Delay | ≤ 4.5 ns at VCC = 4.5–5.5 V - Supports reliable operation in high-speed data paths up to ~100 MHz toggle rate. |
| IOFF Leakage Current | ±2 μA max at VCC = 0 V - Ensures minimal standby current and prevents bus contention during hot-swap or partial system power-down. |
| Operating Temperature | –40 °C to +125 °C - Qualified for under-hood automotive modules, industrial PLC I/O, and extended-temperature sensor interface applications. |
| ESD Protection | HBM >2000 V, CDM >1000 V - Robust handling during PCB assembly and field service without additional protection circuitry. |
Pinout & Package
XSON8 package (SOT833-1): plastic extremely thin small outline, no leads, 8 terminals, body size 1.0 mm × 1.95 mm × 0.5 mm, thermal pad optional, pin 1 index in lower-left corner below marking code.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A | Data Input A (Gate 1 & Gate 2) | Dedicated XOR operand inputs; Schmitt-triggered for noise rejection and monotonic switching on slow edges. |
| 1B, 2B | Data Input B (Gate 1 & Gate 2) | Second operand per gate; compatible with TTL, CMOS, and mixed-voltage sources up to 5.5 V. |
| 1Y, 2Y | Data Output Y (Gate 1 & Gate 2) | True XOR result (A ⊕ B); rail-to-rail CMOS output with ±24 mA sink/source capability at 3.0 V. |
| VCC | Supply Voltage | Single positive supply (1.65–5.5 V); powers both gates and internal IOFF control circuitry. |
| GND | Ground Reference | 0 V reference for all inputs, outputs, and internal logic; must be low-impedance for stable noise immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables clean switching with input rise/fall times up to 20 ns/V (at 1.65–2.7 V), reducing susceptibility to ground bounce and EMI. |
| IOFF partial power-down | Outputs go high-impedance when VCC = 0 V, blocking backfeed current and enabling live insertion into powered backplanes or buses. |
| Overvoltage-tolerant inputs | Accepts 0–5.5 V signals independent of VCC setting-eliminates need for external clamping diodes in mixed-voltage designs. |
| Wide temperature range | Specified from –40 °C to +125 °C ensures consistent XOR truth-table behavior and timing in harsh thermal environments. |
| Low dynamic power | CPD = 15.8 pF enables sub-100 μW dynamic power at 1 MHz (VCC = 3.3 V), suitable for battery-backed or energy-sensitive nodes. |
Applications
| Industrial Sensor Interface | USB-C Power Delivery Negotiation |
|---|---|
|
Use Scenario: Detecting differential status changes between redundant analog sensor outputs before ADC sampling. IC Role / Device Role / Timing Role: XOR gate compares two digitized sensor bits to flag mismatch events; Schmitt inputs reject transient coupling on long traces. Use Value: Enables real-time fault detection without MCU intervention, reducing latency and firmware overhead in safety-critical monitoring. |
Use Scenario: Encoding/decoding PD communication handshake bits in USB-C port controllers with mixed 1.8 V and 3.3 V logic domains. IC Role / Device Role / Timing Role: Performs bit-wise XOR on PD message CRC fields; IOFF prevents bus contention during controller reset sequences. Use Value: Eliminates need for discrete level translators, saving board area and ensuring deterministic timing alignment between PD PHY layers. |
| Motor Phase Encoder Validation | Secure Boot Key XOR Masking |
|
Use Scenario: Verifying quadrature encoder direction consistency by comparing successive A/B phase transitions in BLDC motor drives. IC Role / Device Role / Timing Role: Dual XOR gates compute direction bits (A⊕B_prev, B⊕A_prev); propagation delay <4.5 ns avoids metastability at 100 kHz edge rates. Use Value: Provides hardware-level direction validation before sending pulses to PWM timers-improving position accuracy and stall detection reliability. |
Use Scenario: Performing bitwise XOR between stored cryptographic keys and volatile runtime seeds in secure microcontroller boot ROMs. IC Role / Device Role / Timing Role: Off-chip XOR engine masks key material during readout; low leakage (±0.1 μA) preserves entropy integrity during deep sleep modes. Use Value: Hardens against side-channel glitch attacks by decoupling key masking logic from the main SoC's clock domain and power rails. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G86DBVR | Same logic function and IOFF, but in SOT-23-8 (DBV) package with 2.9 mm × 1.6 mm footprint-larger than XSON8 and higher thermal resistance. | Limited to ≤85 °C ambient; not rated for +125 °C operation-unsuitable for under-hood or high-power industrial enclosures. | Select only if board layout requires through-hole-compatible SMT pads or existing DBV footprint reuse. |
| 74AUP2G86GS,132 | Ultra-low-power AUP family: ICC < 0.5 μA typical, but reduced drive (±4 mA at 3.0 V) and no IOFF-outputs float during power-down. | Designed for battery-powered wearables; lacks backfeed protection-requires external isolation for hot-swap systems. | Prefer for sub-μA standby applications where power dominates over bus integrity or wide temperature range. |
Compared with SN74LVC2G86DBVR and 74AUP2G86GS,132, the 74LVC2G86GD,125 uniquely combines +125 °C rating, IOFF-enabled bus safety, and XSON8 space efficiency-making it optimal for thermally demanding, high-integrity embedded interfaces where board area and reliability are co-constrained.

FAQ
Does 74LVC2G86GD,125 support true 5 V input tolerance when powered at 1.65 V?
Yes. Its inputs are overvoltage tolerant up to 5.5 V regardless of VCC setting, verified per datasheet Table 5 (VI input voltage limit: –0.5 V to +6.5 V) and Table 6 (VI max = 5.5 V at all VCC levels). This allows direct connection to 5 V microcontrollers or sensors without external resistors or clamps-even at minimum 1.65 V supply.
What is the maximum capacitive load the outputs can drive while maintaining specified tpd?
The device is characterized with 30 pF (for VCC ≤ 2.7 V) and 50 pF (for VCC ≥ 3.0 V) loads per Table 10. At 50 pF and VCC = 3.3 V, tpd remains ≤5.9 ns (Table 8). Driving >50 pF increases propagation delay nonlinearly and may exceed timing margins-external buffer recommended beyond 60 pF.
Can 74LVC2G86GD,125 be used in hot-swap applications where VCC is disconnected while signals remain active?
Yes. The IOFF circuit activates automatically when VCC = 0 V, disabling outputs and limiting backfeed current to ±2 μA (Table 7). This meets JEDEC JESD78 requirements for live-insertion safety and prevents corruption of powered downstream buses like I²C or SPI when the device is removed mid-operation.
Is the XSON8 package (SOT833-1) lead-free and RoHS-compliant?
Yes. Per Nexperia's product compliance documentation, 74LVC2G86GD,125 in SOT833-1 packaging is fully RoHS-compliant, halogen-free, and qualified to JEDEC J-STD-020 moisture sensitivity level 1 (MSL1) for unlimited floor life at ≤30 °C/60% RH.
