Product details

Overview

MC74ACT86DR2 from onsemi is a quad 2-input exclusive-OR (XOR) gate in SOIC-14 package, designed for high-speed digital logic applications requiring TTL-compatible inputs and CMOS outputs. It operates at 4.5 V to 5.5 V supply, delivers ±24 mA output drive, exhibits 7.0–10.5 ns propagation delay (tPHL/tPLH), and supports industrial temperature range (−40°C to +85°C). It is used in arithmetic logic units, error detection circuits, and phase comparators.

For engineers reviewing the MC74ACT86DR2 datasheet, pinout, applications, or equivalent options, key selection criteria include its 5 V TTL-compatible input thresholds (VIH = 2.0 V, VIL = 0.8 V), rail-to-rail output swing, low quiescent ICC (≤40 µA), and Pb-free SOIC-14 packaging suitable for automated SMT assembly.

Technical Context

The MC74ACT86DR2 implements four independent XOR logic functions using silicon-gate CMOS technology with buffered TTL-compatible input stages. Each gate features symmetrical input thresholds and rail-to-rail CMOS output drivers capable of sourcing/sinking 24 mA under load.

It is optimized for 5 V systems with guaranteed AC performance at CL = 50 pF and TA = −40°C to +85°C, achieving tPHL ≤ 10.5 ns and tPLH ≤ 10.0 ns. Input hysteresis is not specified; all inputs are standard CMOS with no Schmitt-trigger behavior.

Key Specifications

Parameter	Value and Actual Design Meaning
Logic Function	Quad 2-input XOR gate - enables parity generation, binary addition, and signal comparison across four independent channels
Supply Voltage Range	4.5 V to 5.5 V - ensures compatibility with standard 5 V TTL/CMOS systems without level-shifting
Propagation Delay	tPHL ≤ 10.5 ns, tPLH ≤ 10.0 ns @ VCC = 5.0 V, CL = 50 pF - supports >50 MHz toggle rates in synchronous logic paths
Output Drive	±24 mA - sufficient to directly drive multiple 74-series loads or small LEDs without external buffers
Input Thresholds	VIH = 2.0 V, VIL = 0.8 V @ VCC = 4.5–5.5 V - provides robust noise margin against TTL-level signals
Operating Temperature	−40°C to +85°C - qualified for industrial-grade embedded control and instrumentation environments
Quiescent Current	ICC ≤ 40 µA - enables low-static-power operation in battery-backed or always-on logic subsystems

Pinout & Package

MC74ACT86DR2 is housed in a 14-lead SOIC (Small Outline Integrated Circuit) package per case 751A, with 1.27 mm pitch, 8.55–8.75 mm body width, and 3.80–4.00 mm body length. Pin 1 is marked by a beveled corner or notch.

Pin/Terminal	Circuit Role	Design Meaning
1, 2, 4, 5, 8, 9, 11, 12	XOR Input A/B	Eight total inputs - two per gate (A and B); no internal pull-ups/pull-downs; require defined logic levels
3, 6, 10, 13	XOR Output Y	Four independent CMOS outputs - each capable of driving ±24 mA into resistive or capacitive loads
7	GND	Ground reference for all inputs, outputs, and internal circuitry - must be low-impedance connection
14	VCC	Positive supply rail - decoupling capacitor (0.1 µF ceramic) required within 10 mm of this pin

Key Features

Feature	Design Value
TTL-compatible inputs	VIH = 2.0 V, VIL = 0.8 V at 5 V - eliminates need for level translators when interfacing with legacy 74LS/74F logic
Rail-to-rail CMOS outputs	VOH ≥ 4.4 V, VOL ≤ 0.44 V @ IOL/IOH = ±24 mA - ensures full logic swing and noise immunity in mixed-signal systems
Pb-free SOIC-14 packaging	RoHS-compliant, JEDEC-standard footprint - compatible with reflow soldering profiles and automated optical inspection
High ESD tolerance	Human Body Model > 2000 V - improves handling robustness during board assembly and field service
Low dynamic power dissipation	CPD = 35 pF - minimizes switching current and heat generation in high-frequency clock distribution networks

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74ACT86DR	Identical logic function, pinout, and DC/AC specs; same SOIC-14 package and Pb-free marking; manufactured by Texas Instruments	No functional deviation - validated for drop-in replacement in TI-designated 5 V logic families	Select when sourcing from TI-authorized channels or when BOM requires TI-branded components for qualification traceability
74VHC86M	Wider VCC range (2–5.5 V); lower drive (±8 mA); higher propagation delay (11.5 ns max); same SOIC-14 footprint	Suitable for mixed-voltage systems but not for 24 mA load-driving or sub-10 ns timing-critical paths	Choose only if operating below 4.5 V or where reduced power consumption outweighs speed and drive requirements

Compared with SN74ACT86DR and 74VHC86M, the MC74ACT86DR2 offers superior output drive and tighter propagation delay at 5 V, making it optimal for industrial control logic where signal integrity and timing margin are critical - whereas SN74ACT86DR serves as a direct second-source, and 74VHC86M trades performance for voltage flexibility.

FAQ

What is the recommended supply voltage range for reliable operation of the MC74ACT86DR2?

The MC74ACT86DR2 is specified for reliable operation between 4.5 V and 5.5 V. Operation outside this range may result in undefined logic states or degraded timing margins. The device is not rated for 3.3 V operation - for dual-supply or mixed-voltage designs, consider the 74VHC86M instead. Always use local 0.1 µF ceramic decoupling at the VCC pin.

Does the MC74ACT86DR2 support true TTL input compatibility?

Yes, the MC74ACT86DR2 features TTL-compatible input thresholds: VIH = 2.0 V and VIL = 0.8 V at VCC = 4.5–5.5 V. This allows direct interfacing with 74LS, 74F, and other TTL-family outputs without level shifters. Input hysteresis is not included, so clean signal edges are required to avoid metastability.

Can the MC74ACT86DR2 drive multiple 74-series logic inputs directly?

Yes, the MC74ACT86DR2 can drive up to 10 standard 74LS inputs (each drawing ~0.4 mA) or 4–5 74F inputs (each drawing ~1–2 mA) while maintaining VOH ≥ 4.4 V and VOL ≤ 0.44 V. Its ±24 mA output capability exceeds typical fan-out requirements, enabling simplified interconnect in dense logic boards.

What is the maximum operating temperature specification for the MC74ACT86DR2?

The MC74ACT86DR2 is rated for continuous operation from −40°C to +85°C ambient temperature. Junction temperature must remain ≤150°C under bias; thermal resistance θJA is 116°C/W in SOIC-14. For extended high-temperature environments (>85°C), derating or forced-air cooling is required to maintain reliability.

Is the MC74ACT86DR2 pin-compatible with the MC74AC86DR2?

No, the MC74ACT86DR2 and MC74AC86DR2 are not pin-compatible in functional terms despite identical pinouts. The MC74AC86DR2 uses CMOS input thresholds (VIH = 3.15 V at 4.5 V), while the MC74ACT86DR2 uses TTL thresholds (VIH = 2.0 V). Swapping them may cause logic failures in systems driven by TTL sources.
