Product details
Overview
74HCT86D,653 from Nexperia is a quad 2-input EXCLUSIVE-OR gate in SO14 (SOT108-1) package, designed for digital logic level translation and combinational logic synthesis. It operates at 4.5 V to 5.5 V supply, delivers TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max), supports -40 °C to +125 °C ambient range, and achieves 17 ns typical propagation delay (VCC = 4.5 V, CL = 50 pF). It is used in bus arbitration, parity generation, and enable/disable control circuits.
For engineers reviewing the 74HCT86D,653 datasheet, 74HCT86D,653 pinout, 74HCT86D,653 application, or 74HCT86D,653 equivalent, this page provides verified functional identity, SO14 pin mapping, TTL-level interface behavior, thermal derating data, and validated alternatives for industrial control and embedded logic design.
Technical Context
The 74HCT86D,653 implements four independent XOR gates with TTL-compatible input voltage thresholds-ensuring direct interfacing with legacy 5 V TTL outputs without level shifters. Each gate features clamped inputs enabling safe operation with input voltages exceeding VCC when current-limited.
Its CMOS output stage drives ±4.0 mA at VOH ≥ 3.98 V and VOL ≤ 0.26 V (VCC = 4.5 V), while static supply current remains below 2.0 μA at 25 °C and < 40 μA across full temperature range. Dynamic power dissipation is governed by CPD = 30 pF and load-dependent switching frequency.
Key Specifications

| Input clamp diodes | Allows safe interface to signals up to VCC + 0.5 V using external current-limiting resistors |
| High noise immunity | Guaranteed 0.4 V noise margin at VCC = 5.0 V due to tight VIH/VIL spacing |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transients |
| Wide temperature range | Specified from -40 °C to +125 °C - supports under-hood and industrial control applications |
Applications
| Bus Arbitration Logic | Parity Generator |
|---|---|
Use Scenario: Detecting bus contention between two microcontrollers sharing a common data line. IC Role / Device Role / Timing Role: XOR gate compares address/data lines; output asserts when mismatch occurs.

| Enable/Disable Control | Digital Signal Inversion |
Use Scenario: Enabling peripheral clock gating based on system sleep/wake state. IC Role / Device Role / Timing Role: XOR acts as programmable inverter: one input tied to control signal, other to clock. Use Value: Delivers glitch-free clock enable with <1 ns skew between channels. |
Use Scenario: Inverting serial data stream polarity before feeding into differential line driver. IC Role / Device Role / Timing Role: Single XOR gate with one input held HIGH functions as digital inverter.

Equivalent & Alternatives
The following parts are listed as comparable options for similar XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC86APWR | 3.3 V only (1.65–3.6 V), lower propagation delay (4.5 ns), higher speed grade | Requires level translation when interfacing with 5 V TTL; unsuitable for mixed-voltage backplanes | Select when operating exclusively in 3.3 V systems with timing-critical paths |
| 74HC86D,653 | CMOS input thresholds (VIH = 3.15 V min), wider VCC range (2.0–6.0 V), slower tpd (24 ns @ 4.5 V) | Not TTL-compatible - cannot directly replace 74HCT86D,653 in legacy 5 V designs without redesign | Choose only if migrating from TTL to pure CMOS logic families and revalidating input drive strength |
Compared with SN74LVC86APWR and 74HC86D,653, the 74HCT86D,653 uniquely bridges 5 V TTL and modern CMOS domains without external level shifters, offers superior ESD robustness, and maintains full industrial temperature compliance - making it optimal for brownfield industrial upgrades.

FAQ
What is the maximum recommended supply voltage for 74HCT86D,653?
The absolute maximum supply voltage is +7.0 V, but the recommended operating range is strictly 4.5 V to 5.5 V per JEDEC JESD8C. Operation above 5.5 V risks violating input/output voltage limits and may cause accelerated parametric drift or latch-up under transient conditions.
Can 74HCT86D,653 drive a 50 pF capacitive load at 10 MHz?
Yes - with tpd = 17 ns (typ) and tt = 7 ns (typ) at VCC = 4.5 V and CL = 50 pF, the device fully supports 10 MHz toggle rates. Total dynamic power at that condition is ~1.2 mW (calculated via CPD × VCC² × f × N), well within its 500 mW Ptot rating at 25 °C.
Does 74HCT86D,653 support hot-swap or live-insertion?
No - it lacks powered-off protection circuitry. Applying input signals before VCC stabilization violates the Absolute Maximum Rating for VI (> VCC + 0.5 V), risking internal diode conduction and potential damage. Always ensure VCC is established and stable before asserting inputs.
How does the input clamp diode affect PCB layout?
The integrated clamp diodes allow safe use of series current-limiting resistors (e.g., 1 kΩ) when interfacing to signals exceeding VCC. Layout must place these resistors adjacent to the IC pins, keep traces short, and avoid routing high-dI/dt signals near sensitive analog sections to prevent coupling through shared GND paths.
