Product details
Overview
MC74VHC86DR2 from onsemi is a quad 2-input XOR gate in SOIC-14 package, operating from 2.0 V to 5.5 V, delivering 4.8 ns typical propagation delay at 5 V and full 5.0 V CMOS-level output swings. It supports level translation between 3.3 V and 5.0 V systems and features high noise immunity (28% VCC) for robust digital logic interfacing in industrial control and data path applications.
For engineers reviewing the MC74VHC86DR2 datasheet, pinout, applications, or equivalent options, key selection criteria include input voltage compatibility (CMOS-level), output drive capability (±8 mA), thermal resistance (116 °C/W), latchup immunity (>100 mA), and Pb-free SOIC-14 packaging for automated assembly.
Technical Context
The MC74VHC86DR2 implements four independent XOR logic functions using silicon-gate CMOS technology, with three-stage internal circuitry including buffered outputs for enhanced noise rejection and stable switching. Its inputs tolerate up to 5.5 V, enabling safe interfacing between 3 V and 5 V domains without external level shifters.
It operates across −55 °C to +125 °C, supports 15 pF and 50 pF load conditions, and maintains balanced tPLH/tPHL propagation delays. Input structures include power-down protection, and the device exhibits low dynamic noise (VOLP ≤ 0.8 V) under 50 pF capacitive loading at 5.0 V supply.

Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC86APWR | Lower VCC min (1.65 V), higher max drive (±24 mA), but only rated to +85 °C ambient | Better suited for portable 1.8 V/3.3 V systems; not qualified for extended temperature industrial use | Select when operating below 2.0 V or requiring higher fan-out; verify thermal derating above 85 °C |
| 74HC86N | Same logic function, DIP-14 package, slower tPD (20 ns typ @ 5 V), no 5.5 V input tolerance | Compatible with through-hole prototyping and legacy 5 V TTL systems, but lacks modern voltage flexibility | Choose for breadboard development or cost-sensitive non-automated assembly where SOIC is impractical |
Compared with SN74LVC86APWR and 74HC86N, MC74VHC86DR2 uniquely balances wide voltage operation (2.0–5.5 V), industrial temperature range (−55 °C to +125 °C), and 5.5 V-tolerant inputs - making it optimal for ruggedized embedded systems where supply rail stability cannot be guaranteed.

FAQ
What is the maximum operating temperature for MC74VHC86DR2?
The MC74VHC86DR2 is specified for operation from −55 °C to +125 °C ambient temperature, with junction temperature limited to +150 °C. This rating applies across its full 2.0 V to 5.5 V supply range and makes it suitable for under-hood automotive and industrial motor control environments where thermal stress is significant. Derating curves in the datasheet confirm stable performance at temperature extremes.
Does MC74VHC86DR2 support 3.3 V to 5 V level translation?
Yes, MC74VHC86DR2 supports bidirectional level translation in practice: its inputs tolerate up to 5.5 V regardless of VCC, and its outputs swing rail-to-rail (0 V to VCC). When powered at 5.0 V, it accepts 3.3 V logic inputs and produces full 5.0 V outputs; when powered at 3.3 V, it accepts 5.0 V inputs (clamped internally) and outputs 3.3 V levels - enabling robust interface bridging without external components.
Is MC74VHC86DR2 pin-compatible with other quad XOR gates?
MC74VHC86DR2 is pin- and function-compatible with industry-standard quad 2-input XOR devices including 74HC86, 74HCT86, and SN74LVC86, all in SOIC-14 packages. Pin assignments (A1/B1/Y1 through A4/B4/Y4, GND, VCC) match JEDEC MS-012AC, allowing drop-in replacement in existing layouts - provided voltage and timing requirements align with the selected variant's specifications.
What is the quiescent supply current of MC74VHC86DR2 at 25 °C?
The quiescent supply current (ICC) of MC74VHC86DR2 is 2.0 µA maximum at TA = 25 °C and VCC = 5.5 V, with typical values near 0.1 µA. This ultra-low static current enables use in always-on monitoring circuits and battery-backed subsystems where standby power budget is constrained to single-digit microamps across multiple logic gates.
How does MC74VHC86DR2 handle unused inputs?
Unused inputs on MC74VHC86DR2 must be tied to a valid logic level - either VCC or GND - to prevent floating nodes that cause increased ICC, oscillation, or excessive power dissipation. The datasheet explicitly prohibits leaving inputs open; doing so violates recommended operating conditions and may result in unpredictable output states or accelerated device aging due to shoot-through current in internal stages.
