Product details

Overview

MC74AC86D from onsemi is a quad 2-input exclusive-OR gate in SOIC-14 package, implementing high-performance silicon-gate CMOS logic with 24 mA output drive, 8.5 ns typical propagation delay at 5.0 V, and operation across −40°C to +85°C ambient temperature. It serves as a combinational logic building block in digital control, data path routing, and error detection circuits.

For engineers reviewing the MC74AC86D datasheet, pinout, applications, or equivalent options, this page delivers verified electrical specs, package mapping, functional role in XOR-based logic systems, and validated alternative options for design continuity and supply resilience.

Technical Context

The MC74AC86D implements four independent XOR gates using high-speed CMOS technology, with input thresholds referenced to V_CC (VIH = 2.1 V min at V_CC = 3.0 V; VIL = 0.9 V max), rail-to-rail output swing, and guaranteed 24 mA sink/source capability per output. Its logic function follows Y = A ⊕ B for each gate pair.

It operates within a 2.0–6.0 V supply range, supports 50 pF capacitive loads, exhibits 4.5 pF typical input capacitance, and maintains stable timing performance across industrial temperature extremes without Schmitt-trigger inputs or internal hysteresis.

Equivalent & Alternatives

The following parts are listed as comparable options for similar XOR gate applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74AC86DR	TI part with identical logic function, 2.0–6.0 V supply, ±24 mA drive, but 9.5 ns max t_PHL at 5 V vs. 8.5 ns for MC74AC86D	Same pinout and footprint; slightly higher propagation delay affects tight-timing adder or parity paths	Select when TI supply chain preference or dual-sourcing strategy requires second-source qualification
74VHC86M	ON Semiconductor's VHC variant: lower ICC (2 µA typ), 3.3 V optimized (V_CC = 2–5.5 V), 7.5 ns max t_PLH, but only ±8 mA drive	Not suitable for driving TTL loads or fan-out >10; better for ultra-low-power 3.3 V systems	Choose for battery-powered IoT nodes where static current dominates power budget, not drive strength

Compared with SN74AC86DR and 74VHC86M, MC74AC86D offers the best balance of speed (8.5 ns), drive (±24 mA), and industrial temperature support (−40°C to +85°C) in a widely available SOIC-14 package - making it optimal for robust, medium-speed digital control where load driving and timing margin are both critical.

FAQ

What logic function does the MC74AC86D implement?

The MC74AC86D implements four independent 2-input exclusive-OR (XOR) gates. Each gate outputs a high signal when its two inputs differ (A ≠ B), and a low signal when they match (A = B). This behavior is defined by the Boolean expression Y = A ⊕ B. The MC74AC86D uses silicon-gate CMOS technology to deliver this function with rail-to-rail output swing, 24 mA drive capability, and propagation delays under 9 ns at 5 V - making it suitable for parity generation, digital comparison, and arithmetic sum logic in industrial and communications systems.

Is the MC74AC86D pin-compatible with the MC74ACT86D?

No, the MC74AC86D is not pin-compatible with the MC74ACT86D. While both share identical SOIC-14 pinouts and logic functionality, the MC74ACT86D features TTL-compatible input thresholds (VIH = 2.0 V min at V_CC = 4.5 V), whereas the MC74AC86D uses CMOS thresholds (VIH = 2.1 V min at same condition). Their input voltage recognition levels differ, meaning direct substitution may cause logic misreads in mixed-signal systems. The MC74AC86D remains fully compatible with other 74AC-series devices like MC74AC08 and MC74AC32 in shared PCB layouts.

What is the maximum operating supply voltage for the MC74AC86D?

The absolute maximum DC supply voltage (V_CC) for the MC74AC86D is +6.5 V, but the recommended operating range is 2.0 V to 6.0 V. Operation at 6.0 V is fully characterized per datasheet specifications including propagation delay (9.0 ns max), output drive (±24 mA), and DC output voltage (VOH ≥ 5.4 V, VOL ≤ 0.44 V). Sustained operation above 6.0 V risks parametric degradation or latch-up, especially at elevated temperatures. For reliable long-term use, maintain V_CC within 2.0–6.0 V and include local 100 nF ceramic decoupling at Pin 14.

Does the MC74AC86D support 3.3 V logic systems?

Yes, the MC74AC86D fully supports 3.3 V logic systems. At V_CC = 3.3 V, it guarantees VIH ≥ 1.5 V, VIL ≤ 0.9 V, VOH ≥ 2.9 V, VOL ≤ 0.1 V, and t_PLH/t_PHL ≤ 12.5 ns with 50 pF load. Its CMOS input structure ensures compatibility with 3.3 V CMOS and LVTTL outputs, and its ±24 mA drive can interface directly with 3.3 V buffers or LEDs. The MC74AC86D also meets JEDEC JESD78 latch-up immunity (>100 mA) at 85°C, confirming robustness in mixed-voltage industrial backplanes where 3.3 V and 5 V domains coexist.

What package type is used for the MC74AC86D?

The MC74AC86D is supplied in a SOIC-14 narrow-body package (Case 751A), measuring 8.75 mm × 3.90 mm with 1.27 mm lead pitch and Pb-free finish. This package is distinct from the TSSOP-14 variant (MC74AC86DTR2G) and is optimized for automated surface-mount assembly, thermal dissipation up to 1077 mW in still air, and compatibility with standard SOIC footprints. The MC74AC86D's SOIC-14 body conforms to JEDEC MS-012 standards and supports reflow profiles per J-STD-020, including peak temperatures up to 260°C for 10 seconds at the lead tip.
