Product details
Overview
74HCT2G86DC,125 from Nexperia is a dual 2-input EXCLUSIVE-OR gate in VSSOP8 (SOT765-1) package, operating from 4.5 V to 5.5 V with TTL-compatible inputs, 11 ns typical propagation delay at 4.5 V, and guaranteed operation from –40 °C to +125 °C. It performs bitwise XOR logic for digital signal comparison and parity generation in low-power embedded control interfaces.
For engineers reviewing the 74HCT2G86DC,125 datasheet, 74HCT2G86DC,125 pinout, 74HCT2G86DC,125 application, or 74HCT2G86DC,125 equivalent, this device is selected for deterministic logic-level translation between 5 V TTL sources and CMOS loads, high-noise immunity data path validation, and compact dual-gate implementation where board space and static current < 20 μA are critical.
Technical Context
This IC implements two independent XOR gates with identical truth table behavior: output HIGH only when inputs differ. Each gate features TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 5 V), enabling direct interfacing with legacy 5 V logic families without level shifters.
It uses standard CMOS silicon with integrated input clamp diodes, allowing safe use of current-limiting resistors when interfacing to voltages exceeding VCC. The design supports rail-to-rail output swing (VOH ≥ 4.18 V, VOL ≤ 0.26 V at IO = ±4 mA) and exhibits 1.5 pF typical input capacitance for minimal signal loading.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input XOR: Y = A ⊕ B per gate; enables parity checking and controlled signal inversion. |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard 5 V TTL systems; not compatible with 3.3 V-only rails. |
| Propagation Delay | 11 ns typ (nA/nB to nY) at VCC = 4.5 V - ensures timing predictability in synchronous control paths. |
| Input Thresholds | VIH = 2.0 V min, VIL = 0.8 V max - guarantees reliable recognition of TTL output levels. |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive one 74-series TTL input or multiple CMOS loads. |
| Operating Temperature | –40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor controllers. |
| Static Supply Current | 20 μA max at VCC = 5.5 V - enables always-on status monitoring without battery drain. |
Pinout & Package
VSSOP8 (SOT765-1) package: plastic very thin shrink small outline, 8 leads, body width 2.3 mm, lead pitch 0.5 mm, pin 1 indicator below marking code "T86" in lower-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First XOR gate input A - accepts TTL-level signals; clamped to GND/VCC for overvoltage tolerance. |
| 2 | 1B | First XOR gate input B - electrically identical to 1A; differential pair enables logic comparison. |
| 3 | 1Y | First XOR gate output Y - drives downstream logic with rail-to-rail CMOS swing and 4 mA sink/source. |
| 4 | GND | Ground reference - must be low-impedance return path for both gates' internal current paths. |
| 5 | 2A | Second XOR gate input A - isolated from first gate; allows independent logic operations on same die. |
| 6 | 2B | Second XOR gate input B - shares no internal nodes with 1A/1B; prevents crosstalk in dual-path designs. |
| 7 | 2Y | Second XOR gate output Y - identical electrical specs to 1Y; supports parallel XOR processing. |
| 8 | VCC | Positive supply - powers both gates; decoupling capacitor required within 5 mm for stable switching. |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | Enables direct connection to 74LS/74F outputs without level-shifting circuitry or external resistors. |
| Clamp diode protection | Allows series current-limiting resistors for interfacing to voltages > VCC (e.g., 12 V sensor lines) without damage. |
| High noise immunity | Input hysteresis and 400 mV noise margin at 5 V ensure robust operation in EMI-prone motor control environments. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events. |
| Low dynamic power | 9 pF CPD per gate - minimizes switching current in high-frequency clock distribution or data strobe applications. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC2G86DC,125 | CMOS input thresholds (VIH = 3.15 V min), wider 2.0–6.0 V supply range, 34 ns tpd at 2 V | Better suited for mixed-voltage systems (e.g., 3.3 V MCU + 5 V peripherals); higher static current at 5 V | Select when interfacing with 3.3 V logic or requiring extended VCC range beyond 5.5 V |
| SN74LVC2G86DCUR | 3.3 V only (1.65–5.5 V), 3.5 ns tpd at 3.3 V, 5 V tolerant inputs, 5 pF CPD | Optimized for high-speed 3.3 V FPGA/CPLD I/O; lacks TTL input compatibility | Select for low-latency 3.3 V designs where TTL interface is unnecessary and speed > 10 ns is critical |

FAQ
Can 74HCT2G86DC,125 operate at 3.3 V supply?
No. The 74HCT2G86DC,125 is specified only for 4.5 V to 5.5 V operation per JEDEC JESD8C. At 3.3 V, input thresholds fall outside TTL specification (VIH requires ≥2.0 V but VCC=3.3 V yields insufficient noise margin), and propagation delay becomes undefined. Use 74HC2G86DC,125 or 74LVC2G86 for 3.3 V systems.
What is the maximum capacitive load this device can drive reliably?
The device is characterized up to 50 pF load capacitance per output (Table 10 test condition). Driving >50 pF increases transition time (tt) and propagation delay (tpd) nonlinearly; for 100 pF loads, measured tt exceeds 30 ns at VCC = 4.5 V. Add series termination or buffer stages for heavier loads.
Does this part support hot insertion or live swapping?
No. The 74HCT2G86DC,125 lacks Ioff (power-off protection) or bus-hold circuitry. Connecting or disconnecting while powered risks latch-up due to uncontrolled voltage sequencing on VCC, GND, and I/O pins. Always power-cycle before physical replacement.
How does the input clamp diode affect external resistor selection?
Clamp diodes conduct when input voltage exceeds VCC + 0.5 V or falls below GND − 0.5 V. To limit clamp current to ≤20 mA (absolute max), use R ≥ |VIN − VCC| / 20 mA for overvoltage conditions - e.g., for 12 V input with VCC = 5 V, minimum R = 350 Ω.
