Product details
Overview
SN74LS86ML1 from ON Semiconductor is a quad 2-input exclusive-OR (XOR) gate in SOEIAJ-14 package, operating at 4.75–5.25 V supply, with propagation delays of 12–30 ns and output drive capability of −0.4 mA (high) / 8.0 mA (low), used in digital logic combinatorial circuits including parity generation and error detection.
For engineers reviewing the SN74LS86ML1 datasheet, pinout, applications, or equivalent options, key selection criteria include guaranteed TTL-compatible input thresholds (VIH = 2.0 V, VIL = 0.8 V), ambient temperature range (0–70 °C), output voltage levels (VOH ≥ 2.7 V, VOL ≤ 0.4 V at IOL = 4.0 mA), and SOEIAJ-14 mechanical compatibility.
Technical Context
The SN74LS86ML1 implements four independent XOR logic functions using low-power Schottky bipolar technology. Each gate accepts two TTL-compatible inputs and delivers a single true-output based on the exclusive-OR truth table (Z = A ⊕ B), with no internal feedback or latching behavior.
It operates strictly as a combinational logic device with no clock, enable, or control pins. All timing and DC parameters-including propagation delay asymmetry (tPLH vs tPHL), input clamp diode voltage (−0.65 to −1.5 V), and short-circuit current limits (−20 to −100 mA)-are specified across the full 0–70 °C ambient range and 4.75–5.25 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Family | 74LS (Low-Power Schottky TTL), fully compatible with standard TTL voltage thresholds and loading |
| Supply Voltage | 4.75–5.25 V - ensures stable operation under typical 5 V ±5% rail tolerances |
| Propagation Delay | 12–30 ns - defines maximum combinational path timing for synchronous logic design |
| Output Drive | −0.4 mA (high), 8.0 mA (low) - supports direct fan-out to ≥10 standard TTL inputs |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - guarantees reliable logic-level recognition in mixed-signal environments |
| Operating Temperature | 0 to 70 °C ambient - validated for commercial-grade industrial control and instrumentation |
Pinout & Package
SN74LS86ML1 is housed in a 14-pin SOEIAJ (Small Outline EIAJ) plastic package (Case 965), with gull-wing leads, 1.27 mm pitch, and body dimensions 8.55 × 3.80 × 1.75 mm (L × W × H).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 9, 10, 12, 13 | Input A/B per XOR gate | Eight total inputs distributed across four gates; each pair (e.g., Pin 1 & 2) feeds one XOR function |
| 3, 6, 8, 11 | Output Z per XOR gate | Four independent true-logic outputs; no shared output lines or internal coupling |
| 7 | GND | Ground reference for all logic and power terminals; must be low-impedance connection |
| 14 | VCC | +5 V supply input; decoupling capacitor required within 1 cm for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible interface | Guaranteed VIH/VIL thresholds ensure interoperability with legacy 74-series and microcontroller GPIOs |
| Low-power Schottky architecture | Reduces switching power vs standard TTL while maintaining speed-ICC = 10 mA max at VCC = 5.25 V |
| Robust output stage | 8.0 mA sink capability enables direct LED driving or interfacing to multiple downstream TTL loads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LS86N | DIP-14 package; identical electrical specs but through-hole mounting and larger footprint | Suitable for prototyping, breadboarding, or legacy PCBs requiring through-hole assembly | Select when manual soldering, socketing, or board-level repairability is prioritized over density |
| SN74LS86D | SOIC-14 package (Case 751A); same logic function and DC/AC specs, but different leadform and thermal profile | Better suited for automated SMT assembly and higher-density layouts than SOEIAJ | Choose for volume production with standard SOIC reflow profiles and pick-and-place compatibility |
Compared with SN74LS86N and SN74LS86D, the SN74LS86ML1 offers identical logic performance and DC characteristics but uses the SOEIAJ-14 package-optimized for compact industrial modules where lead pitch and body height constrain layout, and where JEDEC-standard SOIC may not fit mechanical envelopes.

FAQ
What logic function does the SN74LS86ML1 implement?
The SN74LS86ML1 implements four independent 2-input exclusive-OR (XOR) logic gates. Each gate outputs HIGH only when its two inputs differ (A=0,B=1 or A=1,B=0). This behavior is defined by the truth table in the official datasheet and is electrically verified across the full operating temperature and voltage range. The SN74LS86ML1 performs no inversion, latching, or timing functions-it is purely combinational.
Is the SN74LS86ML1 pin-compatible with other 74LS86 variants?
Yes-the SN74LS86ML1 shares identical pinout and logic functionality with all 74LS86 variants (e.g., SN74LS86N, SN74LS86D), as confirmed by the common truth table, terminal numbering, and functional block diagram. However, mechanical compatibility depends on package type: SN74LS86ML1 uses SOEIAJ-14 (Case 965), which differs from DIP-14 and SOIC-14 footprints. The SN74LS86ML1 requires dedicated land pattern design.
What are the absolute maximum ratings for SN74LS86ML1?
The absolute maximum ratings for SN74LS86ML1 are: supply voltage VCC = 7.0 V, input voltage VI = −0.5 to VCC +0.5 V, output short-circuit duration ≤1 second per output, and junction temperature TJ = 150 °C. These limits are specified in the ON Semiconductor datasheet Rev. 8 and define safe operating boundaries beyond which permanent damage may occur. Operation of SN74LS86ML1 outside these values voids warranty and risks failure.
Can SN74LS86ML1 drive LEDs directly?
Yes-SN74LS86ML1 can drive standard 5 mA LEDs directly when configured in active-low mode (output LOW = LED ON), leveraging its 8.0 mA sink capability. For active-high drive, an external pull-up is required since IOH is only −0.4 mA. Always verify current-limiting resistor value using VOL ≤ 0.4 V at IOL = 8.0 mA and forward voltage of the specific LED. This capability applies to SN74LS86ML1 without additional buffering.
Does SN74LS86ML1 support mixed-voltage interfacing (e.g., 3.3 V MCU inputs)?
No-SN74LS86ML1 is a 5 V-only TTL device with VIH = 2.0 V min and VIL = 0.8 V max. While 3.3 V logic HIGH may exceed VIH in some cases, it violates the guaranteed input specification and risks marginal operation due to noise margin erosion and process variation. Interfacing SN74LS86ML1 with 3.3 V systems requires level-shifting circuitry; direct connection is not recommended for production use.
