Product details
Overview
74HCT86S14-13 from Diodes Incorporated is a quad 2-input XOR gate IC in SO-14 package, operating at 4.5V–5.5V supply, delivering 4mA output drive, 32ns max propagation delay (VCC = 4.5V), and TTL-compatible inputs. It performs Boolean Y = A ⊕ B across four independent channels for digital logic decision paths in PC motherboard I/O control and peripheral interface arbitration.
For engineers reviewing the 74HCT86S14-13 datasheet, 74HCT86S14-13 pinout, 74HCT86S14-13 application, or 74HCT86S14-13 equivalent, key selection criteria include guaranteed 4mA sink/source capability at 4.5V, Schmitt-trigger input noise immunity, CMOS power efficiency below 40μA ICC, and SO-14 footprint compatibility with legacy LSTTL designs.
Technical Context
This device implements four independent non-inverting XOR logic functions with push-pull outputs, each satisfying Y = A·B̅ + Ā·B. All inputs feature Schmitt-trigger action for robust noise rejection on slow-rising signals, and are TTL-voltage-level compatible (VIH ≥ 2.0V, VIL ≤ 0.8V) while powered from 4.5–5.5V CMOS rails.
It meets JESD22 ESD ratings of 2kV HBM, 1kV CDM, and 200V MM, and operates across –40°C to +125°C ambient. Propagation delay (tPD) is specified up to 48ns at worst-case temperature and voltage, with transition time (tt) ≤ 22ns under CL = 50pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input exclusive OR (Y = A ⊕ B), non-inverting, independent gates |
| Supply Voltage Range | 4.5V to 5.5V - ensures interoperability with 5V TTL and mixed-signal systems |
| Output Drive | ±4mA at VCC = 4.5V - sufficient to drive standard TTL loads or multiple CMOS inputs |
| Propagation Delay | Max 48ns at VCC = 4.5V, TA = –40°C to +125°C - supports >10MHz toggle rates in synchronous logic |
| Input Compatibility | TTL-level (VIH ≥ 2.0V, VIL ≤ 0.8V) - enables direct interfacing with 74LS/74ALS without level shifters |
| ESD Protection | 2kV HBM, 1kV CDM, 200V MM - exceeds industrial handling requirements per JESD22 |
| Power Consumption | Max 40μA ICC at VCC = 6.0V - ultra-low static current for battery-backed or always-on logic sections |
Pinout & Package
74HCT86S14-13 is housed in a 14-pin Small Outline (SO-14) package with 1.27mm pitch, 8.6mm body width, and gull-wing leads. Pin 1 is marked by a notch or beveled corner; pin 7 is GND and pin 14 is VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | Input A (Gate 1–4) | First data input per XOR gate; Schmitt-triggered for noise margin |
| 2, 5, 10, 13 | Input B (Gate 1–4) | Second data input per XOR gate; TTL-compatible threshold |
| 3, 6, 8, 11 | Output Y (Gate 1–4) | Push-pull CMOS output; sinks or sources 4mA at 4.5V |
| 7 | GND | Ground reference for all logic and power domains |
| 14 | VCC | Positive supply rail (4.5–5.5V); decoupling required within 10mm |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Enables reliable operation with slow or noisy input edges (e.g., mechanical switch debouncing) |
| TTL-compatible input thresholds | Eliminates need for external level-shifting when interfacing with legacy 74LS devices |
| 4mA output drive at 4.5V | Supports fan-out of ≥10 74HCT inputs or direct driving of LED indicators with series resistor |
| CMOS low-power static consumption | ICC ≤ 40μA ensures minimal quiescent loading in always-on control logic |
| SO-14 and TSSOP-14 package options | Enables drop-in replacement in existing SO-14 layouts or space-constrained TSSOP designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74HCT86DR | TI part; identical logic function, same SO-14 package, but tPD max = 33ns @ 5V/25°C (vs. 48ns @ –40°C to +125°C for Diodes) | Optimized for commercial-temp (0°C to 70°C) systems requiring tighter timing margins | Select when operating temperature range is limited and propagation delay consistency is critical |
| 74VHC86M | ON Semiconductor part; wider VCC range (2V–5.5V), lower ICC (≤1μA), but no Schmitt-trigger inputs | Suitable for battery-powered portable devices needing ultra-low standby current | Select when supply voltage may dip below 4.5V or Schmitt-triggering is not required |
Compared with SN74HCT86DR and 74VHC86M, the 74HCT86S14-13 uniquely balances industrial temperature support, built-in noise immunity via Schmitt inputs, and proven 4mA drive strength-making it optimal for ruggedized embedded control where reliability trumps marginal speed gains.

FAQ
What is the maximum operating temperature for 74HCT86S14-13?
The 74HCT86S14-13 is rated for continuous operation from –40°C to +125°C ambient temperature, with junction temperature limits up to +150°C. This rating is validated per the Absolute Maximum Ratings table in DS35335 Rev. 3–2, and applies across the full 4.5V–5.5V supply range.
Can unused inputs be left floating?
No. Per the Recommended Operating Conditions section of the datasheet, all unused inputs must be tied to either VCC or GND to prevent undefined logic states, increased power consumption, and potential oscillation due to noise coupling into high-impedance nodes.
Does 74HCT86S14-13 support mixed-voltage interfacing?
No. The device requires a single 4.5V–5.5V supply and does not support dual-supply or level-shifting operation. Inputs are TTL-compatible but not 3.3V-tolerant; applying 3.3V signals directly risks violating VIH minimum (2.0V) under worst-case VCC = 4.5V conditions.
Is the SO-14 package lead-free and RoHS compliant?
Yes. The 74HCT86S14-13 is fully RoHS compliant per EU Directive 2011/65/EU, with no purposely added lead, and is halogen- and antimony-free ("Green" per Diodes' definition: Br/Cl <900ppm each, total Br+Cl <1500ppm, Sb <1000ppm).
