Product details

Overview

74HCT86D,652 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 in industrial control and embedded interface circuits. It operates from 4.5 V to 5.5 V, delivers propagation delay of 17–48 ns (VCC = 4.5 V), supports -40 °C to +125 °C ambient range, and features TTL-compatible inputs with CMOS outputs.

For engineers reviewing the 74HCT86D,652 datasheet, 74HCT86D,652 pinout, 74HCT86D,652 application, or 74HCT86D,652 equivalent, key selection criteria include input voltage compatibility (TTL-level), output drive strength (±4.0 mA), thermal operating range, SO14 footprint constraints, and static/dynamic power behavior under 50 pF load.

Technical Context

The 74HCT86D,652 implements four independent XOR gates using silicon-gate CMOS technology with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5.0 V). Each gate performs Boolean Y = A ⊕ B, with true complementary output logic and no internal feedback or latching.

It integrates input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors, and meets JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards. ESD protection exceeds 2000 V HBM and 1000 V CDM per JEDEC JS-001/JS-002.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage	4.5 V to 5.5 V - ensures compatibility with 5 V TTL and mixed-voltage systems without level shifters
Propagation Delay	17–48 ns @ VCC = 4.5 V, CL = 50 pF - defines maximum clock/data rate for synchronous logic design
Output Drive	±4.0 mA @ VOH/VOL - sufficient to drive standard 74-series loads or small capacitive buses
Input Thresholds	VIH ≥ 2.0 V, VIL ≤ 0.8 V - guarantees reliable recognition of TTL logic levels across temperature
Operating Temperature	-40 °C to +125 °C - supports extended industrial and under-hood applications
Power Dissipation	CPD = 30 pF - enables dynamic power calculation: PD = 30 × VCC² × fi × 8 (for all 8 inputs switching)
ESD Rating	HBM > 2000 V, CDM > 1000 V - reduces risk of field failure during handling and PCB assembly

Pinout & Package

74HCT86D,652 uses the SO14 (SOT108-1) plastic small outline package: 14-pin, 3.9 mm body width, 1.27 mm lead pitch, gull-wing leads, JEDEC MS-012 compliant.

Pin/Terminal	Circuit Role	Design Meaning
1A, 4A, 9A, 12A	Gate Input A	First input of XOR gates 1–4; accepts TTL-level signals up to VCC + 0.5 V with clamping diode protection
2B, 5B, 10B, 13B	Gate Input B	Second input of XOR gates 1–4; electrically identical to A inputs, fully interchangeable
3Y, 6Y, 8Y, 11Y	Gate Output Y	Complementary XOR result (Y = A ⊕ B); drives CMOS loads with rail-to-rail swing
7	GND	Logic ground reference; must be low-impedance connection to minimize noise coupling
14	VCC	Positive supply; requires local 100 nF decoupling capacitor within 5 mm of pin

Key Features

Feature	Design Value
TTL-Compatible Inputs	Accepts standard 5 V TTL logic thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) while powered from 5 V supply
Wide Temp Range	Specified from -40 °C to +125 °C - eliminates derating concerns in high-ambient environments
Input Clamp Diodes	Enable safe overvoltage input handling (e.g., 12 V control signals) when series resistors limit current to <20 mA
Low ICC Quiescent Current	≤ 2.0 μA typical at VCC = 5.5 V - critical for battery-backed or always-on logic monitoring circuits
High Noise Immunity	CMOS input structure provides >40 % noise margin at VCC = 5 V - resists EMI in motor-drive or switching PSU proximity

Applications

Parity Generator

Control Signal Inversion

Use Scenario: Generating even/odd parity bits for UART or SPI data frames in microcontroller peripherals.

IC Role / Device Role / Timing Role: XOR gate computes cumulative XOR across data bits; each gate processes one bit pair in parallel.

Use Value: Enables real-time parity generation with sub-20 ns latency per stage, supporting baud rates up to 25 Mbps with minimal MCU overhead.

Use Scenario: Inverting enable/disable signals in dual-power domain systems where active-low and active-high versions coexist.

IC Role / Device Role / Timing Role: Acts as programmable signal polarity selector - e.g., converting EN to /EN for companion ICs requiring opposite logic sense.

Use Value: Eliminates need for discrete inverters or firmware-based toggling, reducing BOM count and timing skew between synchronized control paths.

Data Path XOR Logic

Interrupt Request Merging

Use Scenario: Implementing configurable XOR-based data masking or encryption primitives in low-footprint edge sensors.

IC Role / Device Role / Timing Role: Performs bitwise XOR between sensor output and fixed key pattern; four gates support 4-bit parallel operation.

Use Value: Provides deterministic, zero-latency obfuscation without CPU involvement - suitable for tamper-evident telemetry streams.

Use Scenario: Combining multiple interrupt request lines (e.g., from GPIO expanders or ADCs) into a single shared IRQ line for MCU input.

IC Role / Device Role / Timing Role: Wired-OR equivalent via XOR logic: IRQ_A ⊕ IRQ_B ⊕ 0 = IRQ_A ∨ IRQ_B when both are active-low and idle-high.

Use Value: Reduces MCU pin count by 3:1 while preserving individual interrupt detectability through software polling of source registers.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
SN74LVC2G86DCUR	Single dual-input XOR in US8 package; 1.65–5.5 V supply; 3.5 ns typ tpd @ 3.3 V	Lower pin count, higher speed, but only two gates - insufficient for quad-function replacement	Select only when board space is critical and system requires exactly two XOR functions with 3.3 V operation.
74HC86D,653	CMOS-input version (VIH = 3.15 V min); same SO14 package and pinout; 14–36 ns tpd @ 4.5 V	Requires CMOS-level drivers; unsuitable for direct TTL input interfacing without level translation	Choose only if driving sources are CMOS (e.g., FPGA I/O, other 74HC devices) and lower static power (<1 μA ICC) is prioritized.

Compared with SN74LVC2G86DCUR and 74HC86D,653, the 74HCT86D,652 uniquely balances TTL input compatibility, quad-gate density in SO14, and extended temperature support - making it optimal for legacy 5 V industrial control upgrades where pin-for-pin interoperability and robustness outweigh raw speed or ultra-low voltage operation.

FAQ

What is the maximum recommended supply voltage for 74HCT86D,652?

The absolute maximum supply voltage is +7 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 latch-up or accelerated wear-out, especially at elevated temperatures. Designers should maintain VCC ≤ 5.5 V with ±2 % regulation tolerance.

Can 74HCT86D,652 directly interface with 3.3 V microcontrollers?

No - its TTL-compatible inputs require VIH ≥ 2.0 V, which 3.3 V logic typically satisfies, but its outputs swing rail-to-rail (0 V to VCC), so a 5 V-powered device outputs 0–5 V signals incompatible with 3.3 V MCU inputs. A level-shifter or series resistor + clamping diode is required on output lines to prevent damage to 3.3 V receivers.

Does 74HCT86D,652 support hot-swap or live-insertion?

No - it lacks hot-swap protection circuitry such as power-on reset, slew-rate limiting, or back-drive immunity. Applying VCC before inputs stabilize may forward-bias internal clamp diodes, causing excessive current flow. Always ensure power sequencing: VCC established and stable before applying input signals, and inputs held low or high during power-up.

How does the input clamp diode affect external resistor selection?

When interfacing to voltages > VCC (e.g., 12 V control lines), the internal clamp diode conducts when VIN > VCC + 0.5 V. To limit IIK to ≤ ±20 mA (absolute max), the series resistor must be ≥ (VIN − VCC − 0.5 V) / 20 mA. For 12 V input and 5 V supply, R ≥ (12 − 5 − 0.5)/0.02 = 325 Ω - use 330 Ω standard value with 1/4 W rating.
