Product details
Overview
MC74HC86AFR2 from onsemi is a quad 2-input exclusive-OR (XOR) gate in SOIC-14 NB package, operating from 2.0 V to 6.0 V, with propagation delay as low as 17 ns at 6.0 V and output drive capability of 10 LSTTL loads. It interfaces directly with CMOS, NMOS, and TTL logic families and is used in digital arithmetic, parity generation, and signal comparison circuits.
For engineers reviewing the MC74HC86AFR2 datasheet, pinout, applications, or equivalent options, key selection considerations include supply voltage range (2.0–6.0 V), guaranteed propagation delay across temperature (≤150 ns at 125°C), input leakage current (±1.0 µA max), noise immunity, and Pb-free RoHS-compliant packaging.
Technical Context
The MC74HC86AFR2 implements four independent XOR logic functions (Y = A ⊕ B) using high-performance silicon-gate CMOS technology. Each gate has symmetrical input thresholds (VIH = 0.7×VCC, VIL = 0.3×VCC) and rail-to-rail output swing, supporting mixed-voltage system interfacing.
It complies with JEDEC Std No. 7A, features 56 FETs per device (14 equivalent gates), and supports operation from –55°C to +125°C. Input protection circuitry guards against static discharge, and unused inputs must be tied to VCC or GND for stable operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HC86DR | TI part; identical logic function, pinout, and AC specs; wider VCC range (2.0–6.5 V); higher ICC (100 µA max at 125°C) | Same PCB layout; suitable for designs requiring marginally higher supply tolerance | Select SN74HC86DR when sourcing diversity or TI-qualified supply chains are mandated |
| 74HC86D,653 | Nexperia part; same SOIC-14 footprint and DC specs; slightly slower tPLH (21 ns @ 6 V); lower input capacitance (8 pF) | Compatible in most logic designs; may require timing revalidation in >40 MHz systems | Choose 74HC86D,653 for cost-sensitive industrial controls where 4 ns delay margin is acceptable |
Compared with SN74HC86DR and 74HC86D,653, the MC74HC86AFR2 offers the lowest propagation delay at high temperature (150 ns max at 125°C) and tightest VIH/VIL symmetry-critical for robust operation in noisy industrial environments with marginal supply regulation.

FAQ
What logic function does the MC74HC86AFR2 implement?
The MC74HC86AFR2 implements four independent 2-input exclusive-OR (XOR) gates, each performing Y = A ⊕ B. Its truth table yields LOW output when inputs match (both LOW or both HIGH) and HIGH when inputs differ. This behavior is fundamental to parity generation, binary addition, and signal comparison tasks in the MC74HC86AFR2's target applications.
Is the MC74HC86AFR2 pin-compatible with TTL logic devices?
Yes-the MC74HC86AFR2 is pinout-identical to the 74LS86. Its inputs accept LSTTL voltage levels when used with pull-up resistors, and its outputs directly drive LSTTL loads (up to 10). This allows drop-in replacement in legacy LS-TTL designs while delivering CMOS advantages like lower power and wider supply range in the MC74HC86AFR2 implementation.
What is the maximum operating temperature for the MC74HC86AFR2?
The MC74HC86AFR2 is fully specified from –55°C to +125°C across all electrical parameters. This extended temperature range is validated per JEDEC standards and supports deployment in under-hood automotive modules, industrial motor drives, and outdoor telecom infrastructure where ambient thermal stress exceeds commercial-grade limits for the MC74HC86AFR2.
Does the MC74HC86AFR2 require external pull-up resistors on inputs?
External pull-up resistors are required only when interfacing with open-collector or LSTTL outputs to ensure valid HIGH-level input recognition. The MC74HC86AFR2's CMOS inputs have high impedance and will float if left unconnected; unused inputs must be tied to VCC or GND-never left floating-to prevent increased ICC and potential oscillation in the MC74HC86AFR2.
What package type is used for the MC74HC86AFR2?
The MC74HC86AFR2 uses the SOIC-14 NB (Small Outline Integrated Circuit, narrow body) package per case outline 751A, with 1.27 mm lead pitch and 8.55–8.75 mm body width. This surface-mount package is compatible with standard reflow profiles and supports automated assembly in high-volume manufacturing of boards using the MC74HC86AFR2.
