Product details
Overview
74AHCT1G86GV,125 from Nexperia is a single 2-input EXCLUSIVE-OR gate with TTL-compatible input thresholds, 5.5 V supply operation, overvoltage-tolerant inputs (up to 5.5 V), and guaranteed operation from −40 °C to +125 °C. It functions as a logic-level translator in mixed-voltage digital interfaces, enabling interoperability between 3.3 V and 5 V systems in industrial control I/O modules.
For engineers reviewing the 74AHCT1G86GV,125 datasheet, 74AHCT1G86GV,125 pinout, 74AHCT1G86GV,125 application, or 74AHCT1G86GV,125 equivalent, this device is selected for low-power, high-noise-immunity XOR logic in space-constrained PCBs requiring robust level-shifting and extended temperature support.
Technical Context
This device implements standard two-input XOR Boolean logic (Y = A ⊕ B) with symmetrical output impedance and balanced propagation delays. 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 microcontroller outputs while operating from a 4.5–5.5 V supply.
It features overvoltage-tolerant inputs rated to 5.5 V independent of VCC, enabling safe interfacing with higher-voltage signals in mixed-supply domains. Static and dynamic performance is specified across −40 °C to +125 °C, with propagation delay ≤9.0 ns (CL = 15 pF, VCC = 5 V) and CPD = 11 pF for accurate dynamic power estimation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | 2-input EXCLUSIVE-OR (Y = A ⊕ B); enables parity generation, signal comparison, and controlled inversion. |
| Supply Voltage Range | 4.5 V to 5.5 V; supports stable operation across full 5 V rail tolerance and brown-out resilience. |
| Input Thresholds | TTL-compatible: VIH ≥ 2.0 V, VIL ≤ 0.8 V; ensures reliable recognition of 5 V CMOS/TTL outputs. |
| Propagation Delay | ≤9.0 ns (max, CL = 15 pF, VCC = 5 V); guarantees sub-10 ns timing in high-speed control loops. |
| Operating Temperature | −40 °C to +125 °C; qualified for under-hood automotive ECUs, industrial motor drives, and outdoor power electronics. |
| Input Overvoltage Tolerance | Inputs withstand up to 5.5 V regardless of VCC; eliminates need for external clamping in mixed-voltage signal routing. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V; provides robust handling margin during board assembly and field service. |
Pinout & Package
74AHCT1G86GV,125 is housed in the SC-74A (SOT753) surface-mount package: plastic, 5-terminal, leadless outline with body dimensions 3.1 mm × 1.7 mm × 1.3 mm and thermal-enhanced pad design.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Data input | Second XOR operand; accepts TTL/CMOS levels up to 5.5 V, independent of VCC. |
| 2 (A) | Data input | Primary XOR operand; electrically identical to Pin 1; supports bidirectional logic flow. |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry; must be low-impedance to maintain noise immunity. |
| 4 (Y) | Data output | CMOS push-pull output; drives loads up to ±8 mA with VOH ≥ 3.7 V and VOL ≤ 0.55 V at VCC = 4.5 V. |
| 5 (VCC) | Supply voltage | Positive supply rail (4.5–5.5 V); powers internal logic and output stage; requires local 100 nF decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-level input compatibility | Enables direct connection to legacy 5 V microcontrollers and logic families without level-shifter ICs. |
| Overvoltage-tolerant inputs | Accepts 5.5 V signals even when VCC = 4.5 V, simplifying inter-rail signal routing in multi-voltage PCBs. |
| Symmetrical output drive | Equal sourcing/sinking capability (±8 mA) ensures consistent rise/fall times and reduced signal distortion. |
| High noise immunity | Guaranteed 0.8 V noise margin at VCC = 5 V due to tightly controlled VIH/VIL thresholds and hysteresis-free design. |
| Extended temperature range | Validated operation from −40 °C to +125 °C supports deployment in engine control units and industrial inverters. |

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 |
|---|---|---|---|
| 74AHC1G86GV,125 | CMOS input thresholds (VIH = 3.85 V @ VCC = 5.5 V); wider 2.0–5.5 V supply range. | Better suited for pure 3.3 V systems or mixed 2.5/3.3/5 V domains where TTL thresholds are unnecessary. | Select when interfacing with 3.3 V FPGAs or low-VCC microcontrollers; avoid if driving from legacy 5 V TTL sources. |
| SN74LVC1G86DBVR | Lower VCC range (1.65–5.5 V); LVTTL-compatible inputs; slightly higher ICC (max 10 μA vs. 40 μA). | Optimized for battery-powered portable devices; not qualified to +125 °C (only −40 °C to +85 °C). | Prefer for consumer IoT endpoints; reject for under-hood or industrial environments requiring full temperature grade. |

FAQ
Is 74AHCT1G86GV,125 pin-compatible with 74AHC1G86GV,125?
Yes - both share identical SC-74A (SOT753) pinout: Pin 1 = B, Pin 2 = A, Pin 3 = GND, Pin 4 = Y, Pin 5 = VCC. However, input threshold behavior differs: 74AHCT1G86GV uses TTL-compatible VIH/VIL, while 74AHC1G86GV uses CMOS thresholds. Swapping them may cause logic misreads in marginal voltage conditions.
Can 74AHCT1G86GV,125 operate reliably at 3.3 V supply?
No - the 74AHCT variant is specified only for 4.5 V to 5.5 V operation per its recommended conditions table. At 3.3 V, VIH minimum (2.0 V) exceeds 60% of VCC, violating TTL input compatibility and risking undefined output states. Use 74AHC1G86GV instead for 3.3 V systems.
What is the maximum capacitive load this device can drive?
The datasheet specifies timing parameters up to CL = 50 pF, with tpd ≤10.5 ns at VCC = 5 V. Driving >50 pF increases propagation delay nonlinearly and may exceed output current limits (±8 mA). For loads >50 pF, add a series resistor or buffer stage to maintain signal integrity and avoid excessive ICC.
Does 74AHCT1G86GV,125 require external pull-up or pull-down resistors on unused inputs?
No - unused inputs must be tied to VCC or GND to prevent floating nodes, but no external resistors are required. The device has no internal pull-ups/pull-downs; however, its overvoltage-tolerant inputs allow direct connection to fixed rails without risk of latch-up or damage, simplifying termination.
