Product details
Overview
MC74HC86ADR2 from onsemi is a quad 2-input exclusive-OR (XOR) gate in SOIC-14 package, operating across 2.0–6.0 V supply, delivering propagation delay as low as 17 ns at 6.0 V and supporting industrial temperature range (−55 °C to +125 °C). It implements four independent A ⊕ B logic functions with CMOS-compatible inputs and TTL-interfacing capability via pullup resistors.
For engineers reviewing the MC74HC86ADR2 datasheet, pinout, applications, or equivalent options, this page provides verified functional identity, validated pin mapping, confirmed electrical specs per JEDEC 7A, automotive-grade −Q variant availability, and direct substitution guidance for XOR logic in digital control, error detection, and arithmetic circuits.
Technical Context
The MC74HC86ADR2 implements four independent CMOS-based XOR gates using high-performance silicon-gate technology, each with symmetrical input structure and rail-to-rail output swing. Its logic function Y = A ⊕ B = AB̅ + A̅B is realized with 56 FETs per device (14 equivalent gates), ensuring consistent timing behavior across all four channels.
Input compatibility spans standard CMOS outputs and, with external pullups, LSTTL outputs; output drive supports up to 10 LSTTL loads. The device meets JEDEC Standard No. 7A and is Pb-free, halogen-free, and RoHS compliant.

Pinout & Package
MC74HC86ADR2 is housed in a 14-pin SOIC-NB (Small Outline Integrated Circuit – Narrow Body) package, case 751A, with 1.27 mm pitch, 8.55–8.75 mm body width, and 3.80–4.00 mm body length. Pin 1 is marked by notch or bevel; pin 7 is GND, pin 14 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 | First XOR gate input A; tied to logic source or switch; must be terminated to VCC/GND if unused |
| 2 | B1 | First XOR gate input B; complements A1 to generate Y1 = A1 ⊕ B1 |

Applications
| Parity Generator/Checker | Digital Comparator |
|---|---|
Use Scenario: Detecting odd/even bit count in serial data streams or memory words for error detection. IC Role / Device Role / Timing Role: MC74HC86ADR2 computes cumulative XOR across data bits; output = 1 indicates odd parity.

Use Scenario: Comparing two 4-bit binary values (e.g., sensor thresholds vs setpoints) in closed-loop controllers. IC Role / Device Role / Timing Role: MC74HC86ADR2 forms half of a magnitude comparator - A⊕B outputs feed AND/OR logic to determine equality. Use Value: Delivers deterministic 4-bit comparison in ≤68 ns (4× tPLH), faster than microcontroller GPIO polling at 10+ MHz clock rates. |
| Binary Adder Carry Logic | Phase Detection in Clock Recovery |
Use Scenario: Implementing sum and carry outputs in ripple-carry adders for FPGA glue logic or microcontroller expansion. IC Role / Device Role / Timing Role: MC74HC86ADR2 generates sum bits (S = A ⊕ B ⊕ Cin); paired with AND/OR gates for carry chain.

Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC86DR | TI part; identical pinout and logic function; wider VCC range (2–6 V) but higher ICC (100 µA max vs 40 µA) | Same quad XOR role; less suitable for ultra-low-quiescent-power battery monitoring due to higher leakage | Select MC74HC86ADR2 when extended temperature range (−55 °C to +125 °C) and lower ICC are required |
| 74VHC86M | ON Semiconductor VHC family; 3.3 V optimized; tPLH = 4.5 ns at 3.3 V but only rated to +85 °C | Superior speed in 3.3 V systems but not qualified for automotive or extended industrial thermal profiles | Choose MC74HC86ADR2 for designs requiring full −55 °C to +125 °C operation with 5 V tolerance |
Compared with SN74HC86DR and 74VHC86M, the MC74HC86ADR2 offers the broadest temperature coverage and lowest quiescent current among pin-compatible quad XORs, making it optimal for automotive, industrial, and wide-voltage embedded control where reliability trumps marginal speed gains.

FAQ
What logic function does the MC74HC86ADR2 implement?
The MC74HC86ADR2 implements four independent 2-input exclusive-OR (XOR) gates, each computing Y = A ⊕ B = AB̅ + A̅B. This function is used for parity generation, binary addition sum bits, digital comparison, and phase detection. All four gates share common VCC and GND pins but operate electrically isolated from one another.
Is the MC74HC86ADR2 compatible with 3.3 V microcontroller I/O?
Yes, the MC74HC86ADR2 operates reliably from 2.0 V to 6.0 V, including 3.3 V nominal supply. At VCC = 3.3 V, its VIH is guaranteed ≥2.1 V and VIL ≤0.9 V, fully compatible with standard 3.3 V CMOS outputs. Input thresholds scale with VCC, ensuring noise-immune interfacing without level shifters.
Does the MC74HC86ADR2 support automotive applications?
Yes - the MC74HC86ADR2G−Q* variant is AEC-Q100 qualified and PPAP capable, meeting automotive requirements for temperature, reliability, and process control. While the base MC74HC86ADR2 is rated for −55 °C to +125 °C, only the −Q suffix version carries formal automotive qualification documentation and change-control rigor.
What is the maximum propagation delay of the MC74HC86ADR2 at 5 V?
At VCC = 5.0 V and TA = 25 °C, the MC74HC86ADR2 has a maximum propagation delay (tPLH/tPHL) of 20 ns. Over full temperature range (−55 °C to +125 °C), the worst-case delay is 31 ns - specified in the AC Electrical Characteristics table of the official onsemi datasheet (Rev. 8, Feb 2024).
Can unused inputs on the MC74HC86ADR2 be left floating?
No - unused inputs on the MC74HC86ADR2 must be tied to a valid logic level (VCC or GND) to prevent undefined output states, increased power consumption, and potential oscillation. The datasheet explicitly states: "Unused inputs must always be tied to an appropriate logic voltage level." Leaving them floating violates recommended operating conditions and risks system instability.
