Product details

Overview

74AC86SCX_SF501651 from onsemi is a quad 2-input exclusive-OR gate IC in SOIC-14 package, operating from 2.0 V to 6.0 V supply, delivering ±24 mA output drive, with propagation delays as low as 1.5 ns (VCC = 5.0 V, CL = 40 pF), used in digital logic combinatorial circuits for parity generation, signal comparison, and arithmetic functions.

For engineers reviewing the 74AC86SCX_SF501651 datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed VIH/VIL thresholds across 3.3 V/5.0 V rails, ±50 mA absolute output current capability, RoHS-compliant Pb-free SOIC-14 packaging, and AC performance validated down to −40°C.

Technical Context

The 74AC86SCX_SF501651 implements four independent XOR gates with TTL-compatible input thresholds and CMOS-level output swing. Each gate accepts two inputs (A_n, B_n) and produces one true-output (O_n) per IEEE/IEC logic symbol, supporting both wired-AND and open-drain–compatible interfacing when used with external pull-ups.

It operates within a −40°C to +85°C industrial temperature range and supports mixed-voltage system interfacing via 3.0 V, 4.5 V, and 5.5 V V_CC configurations. Input edge rate minimum of 125 mV/ns ensures reliable switching under fast-transition conditions without oscillation or metastability.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Quad 2-input XOR - enables parity checking, binary addition carry control, and data masking in synchronous logic paths
Supply Voltage Range	2.0 V to 6.0 V - supports direct interface with 3.3 V and 5 V logic families without level shifters
Propagation Delay (t_PHL/t_PLH)	1.0 ns min / 9.5 ns max at 5.0 V, CL = 40 pF - ensures timing predictability in high-speed combinational logic blocks
Output Drive Strength	±24 mA - sufficient to directly drive multiple 74AC/ACT loads or small LEDs without buffering
Input Thresholds (VIH/VIL)	V_IH = 3.15 V, V_IL = 1.35 V @ V_CC = 4.5 V - provides 1.1 V noise margin against ground bounce or crosstalk
Quiescent ICC	20 µA max @ V_CC = 5.5 V - enables low-static-power operation in battery-backed or always-on subsystems

Pinout & Package

74AC86SCX_SF501651 is housed in a 14-pin SOIC package (Case 751EF), 3.9 mm wide, with standard 1.27 mm pitch and gull-wing leads. Pin 1 is marked by a beveled corner or notch.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 5, 8, 9, 11, 12	A₀–A₃, B₀–B₃ Inputs	Four independent XOR gate input pairs - A₀/B₀ feed Gate 1; A₁/B₁ feed Gate 2; etc.
3, 6, 10, 13	O₀–O₃ Outputs	True XOR outputs - O₀ = A₀ ⊕ B₀; O₁ = A₁ ⊕ B₁; no internal inversion or enable logic
7	GND	Ground reference for all logic and power domains - must be low-impedance connection to minimize switching noise
14	V_CC	Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 5 mm of this pin

Key Features

Feature	Design Value
Pb-free, Halide-free, RoHS-compliant	Meets EU Directive 2011/65/EU and JEDEC JS709E - eliminates hazardous substances without derating performance
ICC reduced by 50%	Typical quiescent current halved vs. legacy 74LS86 - extends battery life in portable instrumentation
24 mA output sink/source	Drives up to 10 74AC inputs or 20 mA LED load - eliminates need for discrete buffer stages in I/O expansion
Wide V_CC range (2.0–6.0 V)	Single part supports 3.3 V microcontroller interfaces and 5 V legacy peripherals - reduces BOM count

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
74LCX86MTCX	Lower V_CC range (2.0–3.6 V); 3.3 V optimized; 12 mA drive; higher input capacitance (6 pF)	Better suited for 3.3 V-only systems with strict low-voltage compliance; not recommended for 5 V mixed-rail use	Select when operating exclusively at 3.3 V and board space allows TSSOP-14 footprint
SN74AC86D	Identical electrical specs; same SOIC-14 package; TI-branded marking; identical pinout and thermal profile	No functional difference - fully interchangeable in existing designs with TI-sourced boards	Choose for dual-sourcing flexibility where TI's logistics or regional availability advantages apply

Compared with 74AC86SCX_SF501651, the 74LCX86MTCX trades voltage flexibility for lower static power in 3.3 V systems, while SN74AC86D offers identical performance with alternate supply chain access - neither requires PCB changes, but only SN74AC86D guarantees drop-in replacement across all parametric and thermal conditions.

FAQ

What is the maximum operating temperature for the 74AC86SCX_SF501651?

The 74AC86SCX_SF501651 is rated for continuous operation from −40°C to +85°C ambient temperature, with junction temperature limited to 140°C under specified power dissipation. This industrial-grade rating ensures stable XOR logic behavior in factory automation controllers, outdoor telecom gear, and motor drive feedback circuits where thermal cycling occurs.

Does the 74AC86SCX_SF501651 support 3.3 V logic levels?

Yes, the 74AC86SCX_SF501651 fully supports 3.3 V operation: V_CC can be set to 3.3 V ±0.3 V, with guaranteed VIH = 2.1 V and VIL = 0.9 V at TA = +25°C. Its 24 mA drive strength and 6.0 ns typical propagation delay at 3.3 V make it compatible with 74AC/ACT and LVTTL interfaces without level translation.

Is the 74AC86SCX_SF501651 pin-compatible with older 74LS86 devices?

No, the 74AC86SCX_SF501651 is not pin-compatible with 74LS86. While both are quad XORs in 14-pin packages, the 74LS86 uses different input thresholds, slower speed, and higher ICC. The 74AC86SCX_SF501651 follows standard 74AC pinout (A₀/B₀/O₀, A₁/B₁/O₁, etc.), but direct substitution requires validation of timing margins and fanout due to AC family characteristics.

What is the meaning of "SF501651" in the full part number 74AC86SCX_SF501651?

The suffix "SF501651" in 74AC86SCX_SF501651 is an internal Aetrix Electronics traceability code denoting lot-specific sourcing, date code, and distribution channel tracking. It does not affect electrical or mechanical specifications - the core device remains the onsemi 74AC86SCX, SOIC-14, Pb-free, RoHS-compliant quad XOR gate.

Can the 74AC86SCX_SF501651 drive an LED directly?

Yes, the 74AC86SCX_SF501651 can drive a standard 2 mA LED directly when configured as a current-sinking output (LED anode to V_CC, cathode to O_n). At V_CC = 5 V and I_OL = 24 mA, VOL remains ≤0.44 V, ensuring ≥4.56 V forward bias - sufficient for red/green/yellow LEDs with appropriate series resistance (e.g., 220 Ω).
