Product details
Overview
74HC86DR2G from onsemi is a quad 2-input exclusive-OR (XOR) gate in SOIC-14 package, operating from 2.0 V to 6.0 V, with propagation delay ≤26 ns at 6.0 V and output drive capability of 10 LSTTL loads. It performs logic-level signal comparison and parity generation in digital control circuits.
For engineers reviewing the 74HC86DR2G datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range, propagation delay at 5 V, input/output voltage thresholds, and SOIC-14 thermal derating behavior under continuous operation.
Technical Context
The 74HC86DR2G implements four independent CMOS XOR gates using high-performance silicon-gate technology. Each gate computes Y = A ⊕ B with true complementary outputs and supports rail-to-rail input logic levels across its full 2.0–6.0 V supply range.
It features TTL-compatible inputs when pulled up, operates from –55 °C to +125 °C, and delivers guaranteed VOH ≥5.48 V and VOL ≤0.40 V at 6.0 V/5.2 mA load - enabling direct interfacing with legacy TTL and modern CMOS systems without level shifters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input XOR (Y = A ⊕ B), no internal inversion or enable control |
| Supply Voltage Range | 2.0 V to 6.0 V - supports dual-supply systems and battery-powered 3.3 V/5 V logic domains |
| Propagation Delay (tPLH/tPHL) | ≤26 ns at VCC = 6.0 V, CL = 50 pF - enables reliable operation up to ~15 MHz toggle frequency |
| Output Drive | ±5.2 mA at VCC = 6.0 V - drives 10 LSTTL loads or fan-out of ≥20 HC/HCT gates |
| Input Thresholds (VIH/VIL) | VIH = 4.2 V, VIL = 1.8 V at VCC = 6.0 V - ensures noise margin >1.2 V in 5 V systems |
| ESD Rating | HBM 2000 V - meets industrial handling requirements without special ESD precautions |
Pinout & Package
74HC86DR2G is housed in a Pb-free SOIC-14 (Case 751A) package, 8.55–8.75 mm × 3.80–4.00 mm × 1.35–1.75 mm, with standard 1.27 mm pitch and gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 9, 10, 12, 13 | Input A/B for Gates 1–4 | Dedicated XOR inputs; each pair (e.g., Pin 1=A1, Pin 2=B1) feeds one gate |
| 3, 6, 8, 11 | Output Y1–Y4 | True XOR outputs; no open-drain or three-state capability |
| 7 | GND | Ground reference for all inputs, outputs, and internal circuitry |
| 14 | VCC | Positive supply rail; must be decoupled locally to suppress switching noise |
Key Features
| Feature | Design Value |
|---|---|
| CMOS + TTL compatibility | Inputs accept LSTTL levels with pull-up resistors; outputs directly drive CMOS/NMOS/TTL loads |
| Wide temperature range | –55 °C to +125 °C operation - qualified for automotive under-hood and industrial control environments |
| Low static power | ICC ≤40 µA at VCC = 6.0 V and TA = 125 °C - enables always-on logic monitoring without thermal penalty |
| Pb-free packaging | RoHS-compliant SOIC-14 with matte tin lead finish - compatible with standard SnPb and lead-free reflow profiles |
| High noise immunity | Typical noise margin >1.2 V at 5 V - suppresses false triggering in electrically noisy PLC or motor-drive PCBs |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC86DR | Same logic function and SOIC-14 package; TI version has slightly higher ICC (60 µA max at 125 °C) and lower ESD rating (HBM 2000 V same, but MM only 100 V) | Valid for cost-sensitive industrial designs where TI's qualification scope matches system requirements | Prefer 74HC86DR2G when extended temperature reliability or machine-model ESD robustness is critical |
| MC74HC86ADTR2G | Identical onsemi part in TSSOP-14; same electrical specs but 4.9 mm × 4.4 mm footprint and 0.65 mm pitch | Suitable for space-constrained PCBs where SOIC-14 layout area is unavailable | Select 74HC86DR2G for legacy through-hole-compatible layouts or thermal management priority |
Compared with SN74HC86DR and MC74HC86ADTR2G, the 74HC86DR2G offers identical functional behavior with superior machine-model ESD tolerance and optimized thermal derating (–7 mW/°C above 65 °C), making it preferred for high-reliability industrial control modules.

FAQ
What logic family does the 74HC86DR2G belong to, and how does it differ from LS-TTL versions?
The 74HC86DR2G is a high-speed CMOS device with silicon-gate technology, offering 2.0–6.0 V operation, µA-level quiescent current, and rail-to-rail noise margins. Unlike LS-TTL (e.g., 74LS86), it draws negligible static power, tolerates wider supply variation, and provides higher fan-out without external pull-ups - though it requires proper input termination to avoid floating nodes.
Can the 74HC86DR2G operate reliably at 3.3 V, and what are the guaranteed output levels at that voltage?
Yes, the 74HC86DR2G is fully specified down to 2.0 V. At VCC = 3.3 V and TA = 25 °C, VOH ≥3.17 V and VOL ≤0.33 V under 4.0 mA load, providing >0.8 V noise margin for 3.3 V CMOS systems. Propagation delay is ≤31 ns, supporting up to ~10 MHz toggle rates in typical PCB layouts.
Is the 74HC86DR2G pin-compatible with the older 74LS86, and can it be used as a direct replacement?
Yes, the 74HC86DR2G is pin-identical to the 74LS86 and shares the same SOIC-14 pinout. However, due to higher input impedance and lack of internal pull-downs, unused inputs must be tied to VCC or GND - unlike LS-TTL, which tolerates open inputs. No PCB changes are needed, but design review of input biasing is required.
What is the maximum operating temperature for continuous use of the 74HC86DR2G, and how does thermal derating apply?
The 74HC86DR2G is rated for continuous operation from –55 °C to +125 °C. For SOIC-14 packages, power dissipation must be derated by –7 mW/°C above 65 °C ambient. At 125 °C, maximum allowed PD drops to 450 mW - sufficient for typical logic-level switching with <10% duty cycle.
Does the 74HC86DR2G support mixed-voltage interfacing, such as connecting 5 V inputs to a 3.3 V powered device?
No - the 74HC86DR2G does not support mixed-voltage operation. Input voltage must remain within 0 V to VCC. Applying 5 V to a 3.3 V-powered 74HC86DR2G violates absolute maximum ratings (Vin ≤ VCC + 0.5 V) and risks permanent damage. Level-shifting circuitry is required for cross-voltage domain interfacing.
