Product details
Overview
74AHCT1G86GW,125 from Nexperia is a single 2-input EXCLUSIVE-OR gate with TTL-compatible input thresholds, 4.5 V to 5.5 V supply operation, -40 °C to +125 °C temperature range, and TSSOP5 (SOT353-1) package. It functions as a logic-level combinatorial gate in digital signal routing, bus arbitration, and error-detection circuits within industrial control modules.
For engineers reviewing the 74AHCT1G86GW,125 datasheet, 74AHCT1G86GW,125 pinout, 74AHCT1G86GW,125 application, or 74AHCT1G86GW,125 equivalent, this device supports mixed-voltage interface translation, offers symmetrical output drive (±8 mA), and delivers propagation delays as low as 3.5 ns at 5 V with 15 pF load - critical for timing-sensitive combinational logic design.
Technical Context
This device implements a standard two-input XOR Boolean function with true output when inputs differ. Its TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) ensure compatibility with legacy 5 V TTL logic families while maintaining CMOS power efficiency.
It features overvoltage-tolerant inputs rated to 5.5 V independent of VCC, enabling safe level-shifting between 3.3 V and 5 V domains. Propagation delay symmetry (tPLH ≈ tPHL) and balanced output impedance support deterministic timing in feedback or synchronous data paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 2-input EXCLUSIVE-OR (Y = A ⊕ B); enables parity generation, comparator logic, and controlled inversion |
| Supply Voltage Range | 4.5 V to 5.5 V; ensures robust operation across nominal 5 V rails with ±10% tolerance |
| Input Thresholds | TTL-compatible: VIH ≥ 2.0 V, VIL ≤ 0.8 V; guarantees reliable interfacing with 74LS/74F families |
| Propagation Delay | 3.5 ns (typ) at VCC = 5.0 V, CL = 15 pF; supports >100 MHz toggle rates in short-path logic |
| Output Drive | ±8 mA at VCC = 4.5 V; sufficient to drive 10 LSTTL loads or 15 pF transmission line |
| Operating Temperature | -40 °C to +125 °C; qualified for under-hood, motor control, and industrial PLC environments |
| ESD Protection | HBM > 2000 V, CDM > 1000 V; reduces risk of handling damage during assembly and field service |
Pinout & Package
TSSOP5 (SOT353-1) plastic thin shrink small outline package: 5-lead, 1.25 mm body width, 0.65 mm pitch, 1.1 × 2.2 × 1.0 mm footprint, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | B | Second logic input; accepts TTL/CMOS levels up to 5.5 V regardless of VCC |
| 2 | A | Primary logic input; electrically identical to Pin 1, fully interchangeable |
| 3 | GND | Digital ground reference; must be low-impedance connection to minimize switching noise |
| 4 | Y | Inverted XOR output; rail-to-rail swing, symmetrical rise/fall times, drives capacitive loads ≤ 50 pF |
| 5 | VCC | Positive supply; decoupling capacitor (100 nF) required within 5 mm for stable high-speed operation |
Key Features
| Feature | Design Value |
|---|---|
| Overvoltage-tolerant inputs | Withstand 5.5 V applied to A/B pins even when VCC = 3.3 V - enables safe 3.3 V ↔ 5 V bidirectional level translation |
| Symmetrical output impedance | Matched pull-up/pull-down strength ensures equal tPLH/tPHL and eliminates duty-cycle distortion in clocked paths |
| High noise immunity | Input hysteresis and >0.8 V noise margin at VCC = 5 V suppress false triggering in electrically noisy industrial environments |
| Wide temperature qualification | Specified from -40 °C to +125 °C per JESD22-A104; supports extended-range operation without derating |
| Low static current | ICC ≤ 1.0 μA typical at VCC = 5.5 V; minimizes quiescent power in always-on monitoring subsystems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHC1G86GW,125 | CMOS input thresholds (VIH = 3.85 V @ VCC = 5.5 V); wider 2.0–5.5 V supply range | Requires 3.3 V or higher logic sources; unsuitable for direct 5 V TTL driver interfaces | Select when system uses only CMOS logic families and needs lowest static power (ICC < 0.1 μA) |
| SN74LVC1G86DBVR | 3.3 V only supply (1.65–5.5 V), lower 3.5 ns tpd at 3.3 V, LVC-family output drive (±24 mA) | Better suited for modern 3.3 V embedded systems; lacks native 5 V TTL compatibility | Prefer for new 3.3 V designs needing higher drive strength and tighter timing control |

FAQ
What is the maximum input voltage the 74AHCT1G86GW,125 can tolerate on pins A or B?
The device supports overvoltage-tolerant inputs up to 5.5 V regardless of VCC level - meaning A and B pins may safely accept 5.5 V signals even when powered from 3.3 V. This capability is explicitly defined in Section 2 and Table 5 of the datasheet and enables reliable level translation without external components.
Can the 74AHCT1G86GW,125 operate at 3.3 V supply?
No - the 74AHCT1G86GW,125 is specified only for 4.5 V to 5.5 V operation per Table 6. At 3.3 V, input thresholds fall outside TTL specification (VIH requires ≥2.0 V but VCC is too low for guaranteed recognition), and output drive degrades significantly. Use 74AHC1G86GW,125 instead for 3.3 V systems.
Is the 74AHCT1G86GW,125 pin-compatible with other 5-pin XOR gates in TSSOP5?
Yes - it shares identical SOT353-1 (TSSOP5) pinout with industry-standard 5-lead XOR gates including 74AHC1G86GW,125 and SN74LVC1G86DBVR. Pin 1 = B, Pin 2 = A, Pin 3 = GND, Pin 4 = Y, Pin 5 = VCC - verified in Section 6.1 and Figure 6 of the datasheet.
Does the 74AHCT1G86GW,125 support hot-swap or live-insertion?
No - the device lacks explicit hot-swap protection circuitry. While overvoltage-tolerant inputs improve resilience during power sequencing, the absence of Ioff (power-off protection) or IOZ (three-state during power loss) means uncontrolled insertion into live backplanes may cause bus contention or latch-up. Always sequence VCC before applying input signals.
