Product details
Overview
74LVCE1G86W5-7 from Diodes Incorporated is a single 2-input positive EXCLUSIVE OR gate in SOT25 package, operating from 1.4V to 5.5V supply, with ±24mA output drive at 3.3V, 5.5V-tolerant inputs, and IOFF-enabled partial power-down protection-used in voltage level shifting and parity generation circuits.
For engineers reviewing the 74LVCE1G86W5-7 datasheet, 74LVCE1G86W5-7 pinout, 74LVCE1G86W5-7 application, or 74LVCE1G86W5-7 equivalent, this page delivers verified logic function mapping, mixed-voltage interface capability, propagation delay (0.6–3.2 ns at 3.3V), thermal resistance (204°C/W), and RoHS-compliant green packaging details.
Technical Context
This device implements the Boolean function Y = A ⊕ B using CMOS totem-pole output architecture, supporting bidirectional voltage translation between 1.4V and 5.5V domains without level shifters. Its IOFF circuit disables outputs during power-down to prevent backflow current.
Characterized for CL = 15pF and 30/50pF loads, it delivers sub-3.2ns propagation delay at 3.3V and maintains valid logic thresholds across VCC = 1.4–5.5V, including TTL-compatible input thresholds at 3V+ supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4V to 5.5V - enables direct interface with 1.8V, 2.5V, 3.3V, and 5V logic families |
| Output Drive Strength | ±24mA at 3.3V - sufficient to drive multiple LVC/LV inputs or small capacitive loads |
| Propagation Delay (tpd) | 0.6–3.2ns at VCC = 3.3V, CL = 15pF - supports >300MHz toggle rates in low-load configurations |
| Input Voltage Tolerance | Up to 5.5V independent of VCC - allows safe interfacing with higher-voltage signals in mixed-supply systems |
| IOFF Leakage Current | ±10μA max - ensures output isolation during partial power-down without external pull-ups/downs |
| Power Dissipation Capacitance | 22pF at 10MHz - quantifies dynamic power consumption for timing-critical low-power designs |
Pinout & Package
SOT25 (5-pin SC-74A) package with exposed pad not electrically connected; JEDEC-standard footprint, RoHS-compliant lead-free finish, and green molding compound (no Br/Sb).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Data Input | Second XOR operand; 5.5V-tolerant, compatible with TTL and CMOS logic levels |
| 2 (GND) | Ground Reference | Return path for all internal currents; must be low-impedance connection to system ground plane |
| 3 (Y) | Data Output | Totem-pole CMOS output; drives high/low actively; supports bus-repeater and signal-inverter roles |
| 4 (Vcc) | Supply Voltage | Primary power rail; regulates internal biasing and output stage operation across 1.4–5.5V range |
| 5 (A) | Data Input | First XOR operand; identical electrical characteristics to Pin 1; no internal priority or sequencing |
Key Features
| Feature | Design Value |
|---|---|
| Extended Supply Range | Operates from 1.4V (ultra-low-power microcontrollers) to 5.5V (legacy industrial I/O), eliminating need for separate level translators |
| IOFF Partial Power-Down | Automatically disables output when Vcc = 0V, preventing backfeed into powered subsystems during hot-swap or sleep-mode transitions |
| 30% Speed Gain vs. LVC at 1.8V | Reduces propagation delay to 1.4ns (max) at 1.8V, improving timing margin in battery-powered portable logic |
| ESD Robustness | 2kV HBM / 200V MM rating - exceeds JEDEC JESD22-A114/A115, reducing board-level ESD protection component count |
| Low Input Capacitance | 3.5pF typical - minimizes loading on driving gates and preserves signal integrity in high-speed fanout scenarios |
Applications
| Voltage Level Shifting | Bus Repeater / Signal Isolation |
|---|---|

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 | Wider VCC range (1.65–5.5V); lower drive (±24mA only at 3.3V); no 1.4V operation | Lacks ultra-low-voltage support below 1.65V; unsuitable for 1.4–1.6V MCU interfaces | Prefer when design uses ≥1.65V supplies and TI ecosystem alignment is prioritized |
| 74AUP1G86GW,125 | Lower ICC (0.9μA typ); slower max speed (4.6ns at 3.3V); same 1.4–3.6V range | Better for always-on battery sensors; insufficient for >100MHz toggling due to higher tpd | Choose for sub-μA standby power in IoT endpoints where speed is secondary |
Compared with SN74LVC1G86DBVR and 74AUP1G86GW,125, the 74LVCE1G86W5-7 uniquely supports 1.4V operation with 30% faster switching at 1.8V and maintains 5.5V input tolerance-making it optimal for mixed-voltage, low-latency, and partial-power-down use cases.

FAQ
What is the minimum supply voltage at which 74LVCE1G86W5-7 guarantees correct logic operation?
The device is fully specified for operation down to 1.4V VCC, with validated VIH/VIL thresholds, propagation delay, and output drive at that voltage. At 1.2V, only data retention is guaranteed-not functional logic behavior-per Recommended Operating Conditions table.
Can 74LVCE1G86W5-7 safely interface a 5V microcontroller output with a 1.8V FPGA input?
Yes: its inputs tolerate up to 5.5V regardless of VCC, and its output swings rail-to-rail (0V to 1.8V when VCC = 1.8V), meeting FPGA input voltage thresholds. No external resistors or clamps are needed for this interface.
Does the IOFF feature require external circuitry to activate during power-down?
No: IOFF activates automatically when VCC drops below ~0.8V. The output enters high-impedance state without pull-up/down resistors or control signals, preventing current backflow into powered sections of the system.
How does thermal performance differ between SOT25 and DFN1410 packages for this device?
SOT25 has θJA = 204°C/W; DFN1410 is 430°C/W under identical test conditions (FR-4, 2oz copper). The SOT25 offers superior heat dissipation in standard layouts, while DFN1410 provides smaller footprint at the cost of higher junction temperature rise per watt.
