Product details
Overview
74HC86DB,112 from Nexperia is a quad 2-input CMOS EXCLUSIVE-OR gate in SO14 (SOT108-1) package, operating from 2.0 V to 6.0 V supply, with propagation delay of 11 ns at VCC = 6.0 V and CL = 50 pF, used for digital logic arbitration, parity generation, and signal comparison in industrial control and embedded interface circuits.
For engineers reviewing the 74HC86DB,112 datasheet, 74HC86DB,112 pinout, 74HC86DB,112 application, or 74HC86DB,112 equivalent, key selection criteria include input voltage compatibility (CMOS-level), -40 °C to +125 °C temperature range, SO14 mechanical footprint, and guaranteed 25 mA output drive capability per channel.
Technical Context
This device implements four independent XOR gates with symmetrical input clamping diodes enabling safe interfacing to voltages exceeding VCC when current-limiting resistors are used. Each gate exhibits identical truth table behavior: output HIGH only when inputs differ.
It supports dual logic families-74HC86 variant accepts CMOS-level inputs (VIH ≥ 0.7×VCC), while the 74HCT86 variant (not this part) accepts TTL-compatible inputs. Static characteristics include VIH = 4.2 V and VOL = 0.26 V at VCC = 6.0 V and IO = 5.2 mA.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input EXCLUSIVE-OR (XOR); outputs HIGH only when inputs differ |
| Supply Voltage Range | 2.0 V to 6.0 V; enables direct interface with 3.3 V and 5 V systems |
| Propagation Delay | 11 ns typical at VCC = 6.0 V, CL = 50 pF; ensures timing predictability in synchronous logic |
| Output Drive | ±25 mA per output; sufficient to drive multiple standard CMOS inputs or small LED loads |
| Operating Temperature | -40 °C to +125 °C; qualified for extended industrial and under-hood applications |
| Input Clamping | Integrated clamp diodes on all inputs; allows safe overvoltage tolerance with external current limiting |
| ESD Protection | HBM > 2000 V, CDM > 1000 V; reduces risk of handling damage during assembly |
Pinout & Package
74HC86DB,112 uses the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, JEDEC MS-012 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 4A, 9A, 12A | Data Input A | First input of Gates 1–4; accepts CMOS-level signals (VIH ≥ 4.2 V @ VCC = 6 V) |
| 2B, 5B, 10B, 13B | Data Input B | Second input of Gates 1–4; electrically identical to A inputs |
| 3Y, 6Y, 8Y, 11Y | Data Output Y | XOR result of corresponding A/B pair; drives up to ±25 mA into capacitive or resistive loads |
| 7 | GND | Ground reference (0 V); must be low-impedance connection for noise immunity |
| 14 | VCC | Positive supply rail; decoupling capacitor (100 nF) recommended near pin |
Key Features
| Feature | Design Value |
|---|---|
| Wide Supply Range | 2.0 V to 6.0 V operation eliminates need for level shifters between 3.3 V and 5 V subsystems |
| High Noise Immunity | Typical VIH/VIL margins > 1.5 V at VCC = 4.5 V ensure robustness against coupled transients |
| Latch-up Immunity | Exceeds 100 mA per JESD78 Class II Level B; prevents destructive latch-up under transient stress |
| Input Clamp Diodes | Enable safe interface to signals up to VCC + 0.5 V using series resistors, simplifying mixed-voltage designs |
| Low ICC Quiescent Current | Max 40 μA at VCC = 6.0 V and T = +125 °C; supports low-power standby modes |
Applications
| Parity Generator | Digital Signal Comparator |
|---|---|
Use Scenario: Generating odd/even parity bits across 4-bit data buses in UART or SPI peripheral interfaces. IC Role / Device Role / Timing Role: XOR gate array computes bitwise XOR across parallel data lines to produce single parity bit. Use Value: Enables real-time error detection without software overhead; propagation delay ≤11 ns ensures no timing penalty at 10 MHz bus rates. |
Use Scenario: Detecting mismatch between two 4-bit status registers in redundant microcontroller watchdog monitoring. IC Role / Device Role / Timing Role: Four independent XORs compare corresponding bits; OR'd outputs flag any discrepancy. Use Value: Hardware-level fault detection with <25 ns total latency (XOR + OR), faster than CPU polling cycles. |
| Control Signal Arbitration | Phase Difference Detection |
Use Scenario: Resolving conflicting enable requests from two independent subsystems in PLC I/O modules. IC Role / Device Role / Timing Role: XOR acts as exclusive-enable logic: output active only when exactly one request is asserted. Use Value: Prevents simultaneous activation of mutually exclusive resources; immune to contact bounce due to fast edge response. |
Use Scenario: Measuring phase misalignment between clock and feedback signals in motor encoder interfaces. IC Role / Device Role / Timing Role: XOR converts phase difference into pulse-width modulated output for analog integration. Use Value: Linear phase-to-pulse conversion with 11 ns gate delay stability over -40 °C to +125 °C temperature range. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC86D,118 | Same logic function, SO14 package, but rated only to +85 °C ambient (vs. +125 °C) | Not suitable for high-temperature industrial enclosures or automotive under-hood use | Select when cost sensitivity outweighs extended temperature requirement |
| SN74LVC2G86DCUR | 2-channel XOR in SC70-6 package; 1.65–5.5 V supply; 3.7 ns tpd at 3.3 V | Lower pin count, higher speed, but requires redesign for quad functionality and SO14 footprint | Choose for space-constrained, low-voltage (1.8/3.3 V) designs where gate count can be distributed |
Compared with 74HC86DB,112, the 74HC86D,118 sacrifices high-temperature operation for lower unit cost, while SN74LVC2G86DCUR trades package compatibility and channel count for speed and voltage flexibility-neither is drop-in replaceable without layout or thermal validation.

FAQ
What is the maximum output current per pin for 74HC86DB,112?
The absolute maximum output current per pin is ±25 mA, as specified in Table 4 (Limiting Values). This rating applies under conditions where VO remains within -0.5 V to VCC + 0.5 V. Sustained operation near this limit requires thermal derating per package power dissipation limits (500 mW max, derating above 100 °C for SO14).
Can 74HC86DB,112 interface directly with 5 V TTL outputs?
No-74HC86DB,112 has CMOS-level inputs (VIH ≥ 0.7×VCC), so at VCC = 5 V, minimum VIH is 3.5 V. Standard 5 V TTL outputs guarantee only 2.4 V HIGH, which may not reliably register as HIGH. Use 74HCT86 variants for guaranteed TTL compatibility, or add pull-up resistors if marginal margin exists.
Is the SO14 package of 74HC86DB,112 RoHS-compliant and lead-free?
Yes-Nexperia confirms the SOT108-1 (SO14) package used for 74HC86DB,112 meets RoHS Directive 2011/65/EU and is lead-free, with homogeneous material compliance verified per IEC 62321. The device carries the "Pb-free" marking and conforms to JEDEC J-STD-020 moisture sensitivity level MSL3.
Does 74HC86DB,112 require external pull-up or pull-down resistors on unused inputs?
Yes-unused inputs must be terminated to VCC or GND. Floating CMOS inputs cause increased ICC, unpredictable logic states, and potential oscillation due to noise coupling. A 10 kΩ pull-up or pull-down resistor is recommended; internal clamping diodes do not eliminate this requirement.
