Product details
Overview
74LVC86AS14-13 from Diodes Incorporated is a quadruple 2-input XOR gate IC operating across 1.65V–5.5V supply, with 5.5V-tolerant inputs, IOFF-enabled partial power-down protection, and 24mA output sink capability at 3.3V. It enables voltage translation and signal isolation in mixed-voltage logic interfaces on embedded control and peripheral boards.
For engineers reviewing the 74LVC86AS14-13 datasheet, 74LVC86AS14-13 pinout, 74LVC86AS14-13 application, or 74LVC86AS14-13 equivalent, key selection criteria include its dual-rail input tolerance, guaranteed propagation delay ≤5.8ns at 3.3V, IOFF leakage <20μA during power-down, and SO-14 package compatibility with legacy 74-series footprints.
Technical Context
This device implements four independent positive-logic XOR functions (Y = A ⊕ B) with CMOS architecture optimized for low static power and rail-to-rail switching. Its IOFF circuit actively disables outputs when VCC = 0V, preventing back-current flow in hot-swap or partial-power-down systems.
Input thresholds scale with VCC (VIH ≥ 0.65×VCC at 1.65–1.95V; ≥0.7×VCC at 4.5–5.5V), enabling interoperability between 1.8V, 2.5V, 3.3V, and 5V logic domains without external level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65V to 5.5V - supports single-supply operation across 1.8V/2.5V/3.3V/5V logic families |
| Input Voltage Tolerance | Up to 5.5V - allows 3.3V device to accept 5V inputs without clamping diodes or external resistors |
| IOFF Leakage Current | ≤20μA at –40°C to +125°C - ensures safe bus hold and prevents backfeed during system power sequencing |
| Propagation Delay (tPD) | ≤5.8ns at VCC = 3.0–3.6V - meets timing requirements for 100MHz+ synchronous logic interfacing |
| Output Drive Strength | Sinks 24mA at VCC = 3.3V - directly drives standard TTL loads or multiple 74LVC inputs without buffering |
| ESD Protection | 2kV HBM, 1kV CDM, 200V MM - exceeds JEDEC standards for board-level handling and system robustness |
| Power Dissipation Capacitance | 8.4pF per gate at VCC = 3.3V - enables low dynamic power in high-frequency toggle applications |
Pinout & Package
74LVC86AS14-13 is housed in a 14-pin SOIC (SO-14) package with standard 1.27mm pitch, 8.74mm × 3.99mm body, and 1.73mm max height. Pin 1 is marked by a beveled corner or dot; pin numbering follows counter-clockwise sequence from top view.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | Input A (1A, 2A, 3A, 4A) | First XOR operand per gate; 5.5V-tolerant, compatible with higher-voltage signal sources |
| 2, 5, 10, 13 | Input B (1B, 2B, 3B, 4B) | Second XOR operand per gate; independently driven, no internal coupling between gates |
| 3, 6, 8, 11 | Output Y (1Y, 2Y, 3Y, 4Y) | Active-high XOR result; CMOS output stage with rail-to-rail swing and 24mA sink capability |
| 7 | GND | Logic ground reference; must be connected before VCC to ensure proper IOFF activation during power-down |
| 14 | VCC | Primary power supply; powers all four gates and IOFF control circuitry; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Voltage Translation Capability | Accepts 3.3V or 5V inputs while operating from 1.65–3.6V supply - eliminates need for discrete level shifters in mixed-voltage I/O paths |
| Partial Power-Down Protection | IOFF circuit disables outputs when VCC = 0V - prevents current backflow into powered subsystems during hot-plug or staged shutdown |
| Rail-to-Rail Output Swing | VOH ≥ VCC – 0.2V and VOL ≤ 0.2V at light load - ensures full logic margin across entire supply range and temperature |
| Low Dynamic Power | Cpd = 8.4pF/gate at 3.3V - reduces switching power by >40% vs. older 74HC variants at same frequency |
| Robust ESD Immunity | 2000V HBM rating - withstands typical handling environments without additional board-level protection components |
Applications
| USB Peripheral Interface | Industrial PLC Input Isolation |
|---|---|
|
Use Scenario: Isolating USB host-side status lines (e.g., VBUS detect, overcurrent flag) from 3.3V microcontroller GPIO during controller power-down. IC Role / Device Role / Timing Role: XOR gate configured as controlled pass-through using one input tied to enable signal - blocks floating inputs during sleep mode. Use Value: Eliminates need for external MOSFET switches or dedicated isolators; IOFF ensures zero leakage current into powered USB bus. |
Use Scenario: Detecting differential sensor faults (e.g., broken wire, shorted pair) in 24V analog input modules using complementary signal encoding. IC Role / Device Role / Timing Role: XOR compares inverted and non-inverted sensor outputs - high output indicates mismatch caused by open/short condition. Use Value: Enables real-time hardware-level fault detection without CPU intervention; operates reliably across –40°C to +125°C industrial ambient. |
| DDR Memory Address Parity | Legacy ISA Bus Signal Multiplexing |
|
Use Scenario: Generating parity bits for DDR address/command buses where low-latency, deterministic logic is required outside memory controller. IC Role / Device Role / Timing Role: Four XOR gates compute even parity across 8-bit address nibbles - tPD ≤5.8ns ensures setup time compliance at 200MHz clock rates. Use Value: Provides cycle-accurate parity generation with no software overhead or timing uncertainty from programmable logic. |
Use Scenario: Multiplexing shared interrupt request (IRQ) lines from multiple ISA cards onto a single CPU IRQ pin using encoded priority arbitration. IC Role / Device Role / Timing Role: XOR implements priority encoder logic to resolve simultaneous IRQ assertions - 24mA drive strength ensures clean edge integrity over 15cm traces. Use Value: Replaces discrete transistor-based encoders with single-chip solution; SO-14 footprint matches legacy board layouts. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC86APW | TSSOP-14 package; identical electrical specs but 30% smaller footprint and higher thermal resistance (θJA = 159°C/W) | Better suited for space-constrained PCBs; requires tighter thermal management in high-density layouts | Select when board area is critical and thermal derating can be accommodated. |
| 74AHC86D | Higher VCC range (2V–5.5V); no 5.5V input tolerance; IOFF not supported; faster tPD (≤4.5ns at 5V) | Limited to 5V-only systems; cannot interface 3.3V logic to 5V buses without external level shifting | Choose only in pure 5V designs requiring minimal propagation delay and no power-down isolation. |
Compared with SN74LVC86APW and 74AHC86D, the 74LVC86AS14-13 uniquely balances 5.5V input tolerance, IOFF protection, and SO-14 compatibility - making it optimal for retrofitting legacy 74-series designs with mixed-voltage resilience and safe power sequencing.

FAQ
Can 74LVC86AS14-13 operate with VCC = 1.8V while accepting 3.3V inputs?
Yes. The device supports 1.65V–5.5V supply and has 5.5V-tolerant inputs, meaning 3.3V signals applied to any input pin (1A–4B) will not damage the IC or require external clamping, even when VCC = 1.8V. Input thresholds scale accordingly (VIH ≥ 1.17V at 1.8V).
What happens to outputs during power-down when VCC = 0V?
When VCC drops to 0V, the IOFF circuit automatically disables all four outputs (1Y–4Y), placing them in high-impedance state with leakage ≤20μA across –40°C to +125°C. This prevents current backflow from powered downstream circuits into the unpowered IC.
Is the SO-14 package RoHS-compliant and lead-free?
Yes. The 74LVC86AS14-13 uses a fully lead-free SO-14 package compliant with EU RoHS directives 2002/95/EC, 2011/65/EU, and 2015/863/EU. It contains no intentionally added lead and meets Diodes' "Green" definition with <900ppm bromine, <900ppm chlorine, and <1000ppm antimony.
How does propagation delay vary with supply voltage and temperature?
tPD increases with lower VCC and higher temperature: at 3.3V it is ≤4.4ns (25°C), ≤4.6ns (–40°C to +85°C), and ≤5.8ns (–40°C to +125°C). At 1.8V, maximum tPD rises to 9.4ns over full temperature range - design margins must account for worst-case values per application environment.
