Product details
Overview
74LVC1G86FX4-7 from Diodes Incorporated is a single 2-input XOR gate in a 6-pin X2-DFN1409-6 chip-scale package, operating from 1.65V to 5.5V supply, delivering ±24mA output drive at 3.3V, with 5.5V-tolerant inputs and IOFF partial-power-down protection. It performs the Boolean function Y = A ⊕ B and is used for voltage-level shifting and signal isolation in portable computing and consumer electronics.
For engineers reviewing the 74LVC1G86FX4-7 datasheet, 74LVC1G86FX4-7 pinout, 74LVC1G86FX4-7 application, or 74LVC1G86FX4-7 equivalent, key selection criteria include its 1.65–5.5V VCC range, 5.5V input tolerance, IOFF-enabled power-down isolation, and sub-1.4mm × 0.9mm footprint for space-constrained logic interfacing.
Technical Context
This device implements a positive-logic exclusive OR function (Y = A·B̅ + Ā·B) using CMOS technology, supporting mixed-voltage signal translation between 1.8V, 2.5V, 3.3V, and 5V domains. Its IOFF circuit actively disables outputs during power-down, preventing back-current flow when VCC = 0V.
Input thresholds scale with VCC (e.g., VIH ≥ 0.7×VCC at 4.5–5.5V), and propagation delay is specified down to 1.9ns at 5V (–40°C to +125°C). The device meets JESD22 ESD ratings: 2kV HBM, 1kV CDM, and 200V MM.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - Enables direct interface across 1.8V, 2.5V, 3.3V, and 5V logic families without level shifters. |
| Input Voltage Tolerance | Up to 5.5V - Allows safe connection of higher-voltage signals to lower-VCC systems (e.g., 5V GPIO driving 3.3V domain). |
| IOFF Support | Active during VCC = 0V - Prevents damaging current backflow in partial-power-down systems like hot-pluggable modules. |
| Output Drive | ±24mA at VCC = 3.3V - Sufficient to drive multiple LVC loads or small capacitive traces without buffering. |
| Propagation Delay | 1.9ns (min) at 5V, –40°C to +125°C - Supports high-speed timing-critical paths in portable and embedded control logic. |
| ESD Protection | 2kV HBM, 1kV CDM - Meets industrial I/O robustness requirements without external protection components. |
| Operating Temperature | –40°C to +125°C - Qualified for automotive under-hood and industrial edge-node environments. |
Pinout & Package
X2-DFN1409-6 is a 1.4mm × 0.9mm × 0.4mm chip-scale package with 0.5mm pad pitch and bottom-side thermal pad (non-electrical). Pin 1 is marked by a circular fiducial; terminals are arranged in a 3×2 layout with no internal die paddle connection.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A | Data Input | First XOR operand; accepts 0–5.5V regardless of VCC; internally clamped. |
| B | Data Input | Second XOR operand; identical electrical behavior to Pin A. |
| Y | Data Output | Push-pull output delivering true XOR result; sinks or sources up to ±24mA at 3.3V. |
| VCC | Supply Voltage | Primary power rail (1.65–5.5V); powers internal logic and output stage. |
| GND | Ground Reference | Return path for supply and I/O currents; must be low-impedance for noise immunity. |
| NC | No Connection | Internally unconnected pad; must remain floating or tied to GND per layout guidelines - not used for thermal relief. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC range (1.65–5.5V) | Eliminates need for separate voltage regulators in multi-rail systems; supports battery-powered operation down to 1.65V. |
| 5.5V-tolerant inputs | Enables direct interfacing between legacy 5V peripherals and modern low-voltage microcontrollers without external resistors or translators. |
| IOFF partial-power-down | Guarantees high-impedance output state when VCC = 0V, preventing bus contention in modular or hot-swap architectures. |
| Low dynamic power (14pF Cpd) | Reduces switching current and system-level EMI in high-frequency clock/data paths, especially in portable devices. |
| Small-footprint DFN package | 1.4mm × 0.9mm area saves PCB real estate in ultra-compact designs such as wearables and IoT sensors. |
Applications
| USB OTG Signal Routing | Industrial Sensor Interface |
|---|---|
Use Scenario: Isolating USB ID pin detection logic during host/peripheral role switching in dual-role devices. IC Role / Device Role / Timing Role: XOR gate compares ID pin state against system configuration to assert correct USB role (host vs. peripheral). Use Value: Eliminates discrete transistor-based switching; leverages 5.5V input tolerance to interface directly with USB PHY's 3.3V/5V ID line. | Use Scenario: Detecting fault conditions (e.g., open-wire or short) in 4–20mA loop transmitters via differential sensor excitation. IC Role / Device Role / Timing Role: Logic-level XOR compares two complementary excitation signals to generate fault flag on mismatch. Use Value: Operates reliably across –40°C to +125°C ambient; IOFF prevents false faults during power sequencing of analog front-end. |
| Mobile Display Backlight Control | Automotive Infotainment I/O Expansion |
Use Scenario: Enabling PWM-controlled LED backlight only when both enable and sync signals are active. IC Role / Device Role / Timing Role: XOR acts as configurable gate for PWM injection into backlight driver, toggling based on panel power and brightness command. Use Value: Sub-2ns propagation delay ensures minimal PWM duty-cycle distortion; 1.4mm × 0.9mm footprint fits within tight display module layouts. | Use Scenario: Translating CAN transceiver status flags (TXD/RXD) into unified interrupt signal for MCU GPIO expansion. IC Role / Device Role / Timing Role: XOR combines two independent status bits (e.g., TX complete and RX ready) to reduce GPIO count on infotainment SoC. Use Value: 5.5V input tolerance allows direct connection to 5V CAN PHY outputs; IOFF protects MCU during ignition-cycle power ramp-up. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC1G86DBVR | SOT-23-5 package (3.0 × 2.8 mm); no NC pin; slightly higher θJA (204°C/W vs. 470°C/W). | Larger footprint; less suitable for ultra-dense layouts but easier hand-soldering and probe access. | Select when board assembly uses standard pick-and-place for SOT-23 or requires simplified routing without NC handling. |
| 74AUP1G86GW,125 | NXP part in SC-70-5; lower ICC (0.9μA typical vs. 10μA); VCC range 0.8–3.6V only. | Not 5.5V-tolerant; unsuitable for mixed 5V/3.3V interfaces; optimized for ultra-low-power battery use. | Select only for sub-3.6V systems where static current <1μA is critical and 5V compatibility is unnecessary. |
Compared with SN74LVC1G86DBVR and 74AUP1G86GW,125, the 74LVC1G86FX4-7 uniquely balances ultra-small size, full 1.65–5.5V operation, and 5.5V input tolerance - making it optimal for space-constrained, multi-voltage portable and automotive control logic where IOFF and thermal performance are essential.

FAQ
Can 74LVC1G86FX4-7 operate with VCC = 1.5V?
No. The absolute minimum recommended VCC is 1.65V per datasheet Section 6. Below this, output drive strength degrades significantly, and input thresholds become undefined. While data retention is guaranteed at 1.5V, functional logic operation is not supported.
Is the NC pin on 74LVC1G86FX4-7 required to be grounded?
No. The NC pin is internally unconnected and must remain electrically floating. Diodes Incorporated's package outline and layout guidelines explicitly prohibit connecting NC to GND or any other net, as it may compromise thermal or electrical performance due to unintended coupling.
What is the maximum capacitive load this XOR gate can drive reliably?
Based on measured Cpd = 14pF and typical tPD = 2.3ns at 3.3V, the device reliably drives ≤30pF loads while maintaining specified timing. For heavier loads (>50pF), propagation delay increases nonlinearly and output rise/fall times degrade - external buffering is recommended beyond that point.
Does IOFF functionality activate automatically when VCC drops below threshold?
Yes. IOFF engages when VCC falls below ~0.8V (per characterization data), forcing outputs into high-impedance state regardless of input states. This occurs without external control signals and is inherent to the gate's internal bias network design.
