Product details
Overview
74HCT2G86DP,125 from Nexperia is a dual 2-input EXCLUSIVE-OR gate in TSSOP8 (SOT505-2) package, operating from 4.5 V to 5.5 V supply, with TTL-compatible inputs, propagation delay of 11–48 ns at VCC = 4.5 V, and specified for -40 °C to +125 °C ambient temperature - used in digital logic arbitration, parity generation, and signal comparison circuits.
For engineers reviewing the 74HCT2G86DP,125 datasheet, 74HCT2G86DP,125 pinout, 74HCT2G86DP,125 application, or 74HCT2G86DP,125 equivalent, this device serves as a low-power, high-noise-immunity XOR logic building block in industrial control, sensor interface, and serial data encoding subsystems where precise timing and level translation between TTL and CMOS domains are required.
Technical Context
The 74HCT2G86DP implements two independent XOR gates with true complementary CMOS output stages, supporting rail-to-rail switching across its full operating voltage range. Each gate features input clamp diodes enabling safe interfacing to voltages exceeding VCC when current-limiting resistors are used.
Its TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V) ensure compatibility with legacy 5 V TTL logic families, while its CMOS output drive (VOH ≥ 4.18 V at IO = –4 mA, VOL ≤ 0.26 V at IO = 4 mA) maintains robust noise margins in mixed-signal environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 4.5 V to 5.5 V - ensures stable operation in standard 5 V systems with ±10 % tolerance. |
| Propagation Delay | 11 ns (typ), 48 ns (max) at VCC = 4.5 V - defines worst-case timing budget for synchronous logic paths. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - guarantees reliable recognition of TTL logic levels without level-shifting circuitry. |
| Output Drive | ±4.0 mA at VCC = 4.5 V - supports fan-out of ≥10 LS-TTL loads or direct connection to 50 pF capacitive loads. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor drives. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - reduces risk of field failure during handling and PCB assembly. |
| Power Dissipation | 250 mW max (TSSOP8) - enables use in thermally constrained space-limited applications without forced cooling. |
Pinout & Package
TSSOP8 plastic thin shrink small outline package (SOT505-2); 8 leads; body width 3 mm; lead length 0.5 mm; pin 1 index located below marking code in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First XOR gate input A - accepts TTL/CMOS logic signals; clamped to protect against overvoltage. |
| 2 | 1B | First XOR gate input B - paired with 1A to generate exclusive-OR output at pin 3. |
| 3 | 1Y | First XOR gate output Y - drives downstream logic or bus lines with CMOS-compatible voltage swing. |
| 4 | GND | Ground reference - must be low-impedance return path for both logic and supply currents. |
| 5 | 2Y | Second XOR gate output Y - electrically isolated from 1Y; supports independent logic functions. |
| 6 | 2B | Second XOR gate input B - shares same electrical characteristics and layout constraints as 1B. |
| 7 | 2A | Second XOR gate input A - symmetrical to 1A; enables dual-gate implementation without external routing. |
| 8 | VCC | Positive supply - decoupling capacitor (100 nF) required within 5 mm for stable high-speed switching. |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range | Operates from 4.5 V to 5.5 V - eliminates need for dedicated LDOs in 5 V systems with ripple or droop. |
| Input clamp diodes | Enables safe interface to signals up to VCC + 0.5 V using series resistors - avoids external protection components. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events. |
| High noise immunity | Typical noise margin > 1.2 V at VCC = 5 V - suppresses false triggering in electrically noisy factory-floor environments. |
| Low ICC quiescent current | ≤ 1.0 μA at VCC = 5.5 V - minimizes standby power in battery-backed or energy-harvesting applications. |
Applications
| Industrial PLC I/O Expansion | Serial Data Parity Generator |
|---|---|
|
Use Scenario: Adding discrete logic-based status monitoring to modular I/O racks where microcontroller GPIOs are constrained. IC Role / Device Role / Timing Role: Performs real-time XOR of two sensor enable lines to detect mismatched actuation states before relay activation. Use Value: Detects wiring faults or stuck sensors by generating fault flag on mismatch - no firmware update or CPU cycle overhead required. |
Use Scenario: Generating odd/even parity bits for UART or SPI data frames in resource-constrained edge nodes. IC Role / Device Role / Timing Role: Computes bitwise XOR across 8-bit data bus using cascaded gate pairs to produce single parity output. Use Value: Adds error detection capability with <15 ns added latency - preserves real-time throughput in deterministic communication stacks. |
| Digital Encoder Interface | TTL-to-CMOS Level Translator |
|
Use Scenario: Interfacing quadrature encoder outputs to FPGA or MCU inputs requiring clean phase-difference detection. IC Role / Device Role / Timing Role: Compares A/B channel transitions to determine rotation direction via XOR truth table evaluation. Use Value: Resolves direction unambiguously even with slow edge rates (≥100 ns rise/fall) due to guaranteed setup/hold timing. |
Use Scenario: Bridging legacy 5 V TTL logic (e.g., 74LS series) to modern 5 V CMOS microcontrollers with stricter VIH/VIL. IC Role / Device Role / Timing Role: Accepts TTL input thresholds while driving CMOS-compatible VOH/VOL levels to downstream ICs. Use Value: Eliminates need for discrete transistor translators or dedicated level-shifter ICs - reduces BOM count and layout area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G86DCUR | Lower VCC range (1.65–5.5 V), faster tpd (5.8 ns typ), but only rated to +85 °C. | Suitable for commercial-grade portable electronics; not qualified for extended temperature industrial use. | Select when speed > 11 ns and ambient stays ≤ +85 °C; avoid if board operates near engine compartments or power converters. |
| 74AHC2G86DP,125 | CMOS input thresholds (VIH = 3.15 V min), higher noise immunity, but incompatible with pure TTL sources. | Requires compatible CMOS drivers; unsuitable for direct connection to 74LS or 74F logic without pull-ups. | Choose for new designs using exclusively CMOS logic families; reject if interfacing with legacy TTL peripherals. |
Compared with SN74LVC2G86DCUR and 74AHC2G86DP,125, the 74HCT2G86DP,125 uniquely balances TTL input compatibility, extended temperature support, and proven industrial reliability - making it the preferred choice for retrofitting or upgrading legacy 5 V control systems.

FAQ
Can 74HCT2G86DP,125 operate at 3.3 V supply?
No. The 74HCT2G86DP,125 is specified only for 4.5 V to 5.5 V operation per its recommended conditions. At 3.3 V, input thresholds (VIH ≥ 2.0 V) become marginal, and output drive degrades significantly - use 74LVC2G86 or 74AHC2G86 instead for 3.3 V systems.
What is the maximum capacitive load this device can drive reliably?
The 74HCT2G86DP,125 is characterized up to 50 pF load capacitance in dynamic tests (Table 10). Driving >50 pF increases propagation delay nonlinearly and may cause overshoot; for >100 pF loads, add a series resistor (22–47 Ω) near the output to dampen ringing.
Does this part support hot insertion or live insertion into powered backplanes?
No. The 74HCT2G86DP,125 lacks hot-swap protection circuitry. Its input clamp diodes are not rated for sustained current during live insertion, and VCC sequencing violations may cause latch-up. Use dedicated hot-swap controllers or power sequencers for such applications.
How does the input clamp diode affect design when interfacing to 12 V signals?
The internal clamp diodes allow safe interface to 12 V signals only when series current-limiting resistors restrict IVCC or IGND current to ≤20 mA (per Table 5). For 12 V → 5 V translation, a 390 Ω resistor limits peak current to ~18 mA - verify thermal dissipation in resistor selection.
