Product details
Overview
MC74AC86M from onsemi is a quad 2-input XOR gate logic IC in EIAJ-14 (JEDEC MS-012) package, operating at 2.0–6.0 V supply, delivering ±24 mA output drive, with propagation delay as low as 1.5 ns at 5.0 V and 50 pF load, used in digital signal routing, parity generation, and control-state encoding in industrial PLC I/O modules.
For engineers reviewing the MC74AC86M datasheet, pinout, applications, or equivalent options, key selection criteria include its TTL-compatible input thresholds at 5 V, rail-to-rail output swing, low quiescent ICC (≤40 µA), and guaranteed operation across −40°C to +85°C ambient temperature range.
Technical Context
The MC74AC86M implements four independent CMOS-based XOR gates using advanced AC-series silicon, supporting both 3.3 V and 5 V logic systems with dual-voltage input thresholds (VIH = 2.1 V min at VCC = 3.0 V; VIH = 3.15 V min at VCC = 4.5 V). It features no internal Schmitt-trigger inputs and relies on standard CMOS switching behavior.
Each gate exhibits matched tPLH/tPHL propagation delays (1.5–9.0 ns over voltage/temperature), supports fan-out of ≥10 LS-TTL loads, and maintains output voltage compliance (VOH ≥ 4.4 V, VOL ≤ 0.1 V) under ±24 mA DC loading at VCC = 4.5–5.5 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input exclusive-OR (XOR) gate - enables parity checking, signal comparison, and arithmetic carry logic |
| Supply Voltage Range | 2.0 V to 6.0 V - supports mixed-voltage system interfacing and battery-backed 3.3 V/5 V designs |
| Output Drive | ±24 mA per output - drives multiple LS-TTL inputs or small capacitive loads without external buffers |
| Propagation Delay | 1.5 ns (typ) at VCC = 5.0 V, CL = 50 pF - enables use in sub-100 MHz synchronous data paths |

Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74AC86N | Different manufacturer (TI); identical AC-series electrical specs but distinct marking and packaging (PDIP-14 only) | Same functional behavior; not recommended for new SMT designs due to through-hole-only availability | Select MC74AC86M for EIAJ-14 SMT compatibility and industrial temp grade; SN74AC86N only where legacy PDIP footprint exists |
| 74VHC86M | Higher speed (tPD = 1.8 ns typ), lower ICC (≤2 µA), but narrower VCC range (2.0–5.5 V) and reduced output drive (±8 mA) | Better for ultra-low-power battery sensors; insufficient drive for TTL fan-out or long trace routing | Choose MC74AC86M when ±24 mA drive and −40°C to +85°C operation are mandatory; 74VHC86M suits low-noise, low-Icc portable logic |
Compared with SN74AC86N and 74VHC86M, the MC74AC86M uniquely combines industrial temperature rating, EIAJ-14 SMT packaging, and robust ±24 mA output drive - making it optimal for space-constrained, high-reliability industrial control logic where board area and thermal margin are critical.

FAQ
What logic function does the MC74AC86M implement?
The MC74AC86M implements four independent 2-input exclusive-OR (XOR) gates. Each gate outputs HIGH only when its two inputs differ - a fundamental building block for parity generation, signal comparison, and arithmetic sum computation. All four gates share common VCC and GND connections and operate simultaneously with matched propagation characteristics.
What supply voltage range is supported by the MC74AC86M?
The MC74AC86M supports a supply voltage range of 2.0 V to 6.0 V, with guaranteed operation across the full industrial temperature range (−40°C to +85°C). At VCC = 3.0 V, input thresholds are VIH ≥ 2.1 V and VIL ≤ 0.9 V; at VCC = 4.5–5.5 V, it meets TTL-compatible levels (VIH ≥ 3.15 V, VIL ≤ 1.35 V), enabling interoperability with mixed-voltage systems.
Does the MC74AC86M have Schmitt-trigger inputs?
No, the MC74AC86M does not feature Schmitt-trigger inputs. Its inputs follow standard CMOS threshold behavior with no hysteresis. The datasheet explicitly notes "′AC Devices except Schmitt Inputs" in the Recommended Operating Conditions table, and input rise/fall time specifications assume monotonic transitions without noise immunity enhancement.
What is the maximum output current capability of the MC74AC86M?
The MC74AC86M delivers ±24 mA DC output current per pin - meaning it can source up to 24 mA when driving HIGH and sink up to 24 mA when driving LOW. This is verified under VCC = 4.5–5.5 V and TA = −40°C to +85°C, and supports fan-out to ≥10 LS-TTL loads without external buffering.
Which package type is used for the MC74AC86M?
The MC74AC86M uses the EIAJ-14 (JEDEC MS-012) surface-mount package, also referenced as CASE 965. It is a 14-pin gull-wing SOIC variant with 0.150″ body width and 0.025″ lead pitch, distinct from standard SO-14 (CASE 751A) and TSSOP-14 (CASE 948G) variants offered in the same 74AC86 family.
