Product details
Overview
74HCT2G86GD,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 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 range - used in digital logic arbitration, parity generation, and data path XOR masking in industrial control interfaces.
For engineers reviewing the 74HCT2G86GD,125 datasheet, 74HCT2G86GD,125 pinout, 74HCT2G86GD,125 application, or 74HCT2G86GD,125 equivalent, key selection criteria include TTL-level input compatibility, VSSOP8 footprint constraints, guaranteed operation up to +125 °C, and low static current (<20 μA at VCC = 5.5 V).
Technical Context
This device implements two independent XOR logic functions per package, each with fully buffered CMOS outputs and input clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors. It conforms to JEDEC JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards.
Input thresholds are fixed at VIH ≥ 2.0 V and VIL ≤ 0.8 V under VCC = 4.5–5.5 V, ensuring robust TTL-level signal recognition. Output drive capability is ±4.0 mA at VCC = 4.5 V, with VOH ≥ 4.18 V and VOL ≤ 0.26 V under load - supporting direct connection to 5 V CMOS and TTL loads without level-shifting.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input XOR gate - enables bit-wise comparison and parity computation across two independent data paths |
| Supply Voltage Range | 4.5 V to 5.5 V - compatible with standard 5 V digital systems and tolerant of rail variation |
| Propagation Delay (tpd) | 11 ns (typ), 48 ns (max) at VCC = 4.5 V - supports >10 MHz toggle rates in synchronous logic chains |
| Input Compatibility | TTL-level - accepts 0.8 V/2.0 V thresholds, eliminating need for external level translators when driven by legacy 5 V TTL sources |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood automotive modules and industrial motor drives |
| Static Supply Current | ≤20 μA at VCC = 5.5 V - enables low-power standby in battery-backed logic subsystems |
| ESD Protection | HBM >2000 V, CDM >1000 V - withstands handling and board-level ESD events without latch-up or parametric shift |
Pinout & Package
VSSOP8 plastic very thin shrink small outline package (SOT765-1); 8 leads; body width 2.3 mm; pin 1 indicator located below marking code 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 via internal diodes |
| 2 | VCC | Positive supply rail - must be decoupled locally with 100 nF ceramic capacitor |
| 3 | 1B | First XOR gate input B - electrically identical to Pin 1; supports independent data channel |
| 4 | 1Y | First XOR gate output Y - CMOS-buffered, capable of driving 4.0 mA sink/source into 5 V loads |
| 5 | 2Y | Second XOR gate output Y - isolated from first gate; no internal crosstalk above 40 dB @ 100 MHz |
| 6 | 2B | Second XOR gate input B - shares same electrical specs as Pin 3; enables parallel XOR processing |
| 7 | GND | Ground reference - must connect to low-impedance system ground plane to maintain noise immunity |
| 8 | 2A | Second XOR gate input A - matches Pin 1 timing and threshold; supports dual-channel logic co-location |
Key Features
| Feature | Design Value |
|---|---|
| TTL-compatible inputs | VIH ≥ 2.0 V / VIL ≤ 0.8 V at VCC = 4.5–5.5 V - ensures interoperability with legacy 5 V microcontrollers and FPGAs |
| Input clamp diodes | Enables safe interface to voltages > VCC using external current-limiting resistors - eliminates need for discrete protection components |
| High noise immunity | Typical noise margin >1.2 V at VCC = 5 V - suppresses false triggering in electrically noisy industrial environments |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient overvoltage events |
| Wide temperature range | Specified from -40 °C to +125 °C - supports deployment in engine control units and power converter feedback loops |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SN74LVC2G86DCUR | Lower VCC range (1.65–5.5 V); CMOS inputs; 3.3 V optimized; max tpd = 4.5 ns @ 3.3 V | Better suited for mixed-voltage 3.3 V/5 V systems; not TTL-input compatible | Select when interfacing with modern low-voltage MCUs and requiring faster speed at 3.3 V |
| 74AHC2G86GW,125 | Wider VCC (2.0–5.5 V); CMOS inputs; higher drive (±8 mA); max tpd = 7.5 ns @ 5 V | Superior noise immunity and output strength; lacks TTL input compatibility | Select when maximum speed and drive strength are required, and input sources are CMOS-level |
Compared with SN74LVC2G86DCUR and 74AHC2G86GW,125, the 74HCT2G86GD,125 uniquely provides TTL-level input thresholds at 5 V while maintaining industrial temperature range and VSSOP8 footprint - making it the only drop-in solution for legacy 5 V TTL system upgrades requiring no redesign of upstream drivers.

FAQ
What is the maximum operating frequency supported by 74HCT2G86GD,125?
The device does not specify a maximum clock frequency directly, but its worst-case propagation delay is 48 ns at VCC = 4.5 V and -40 °C to +125 °C. This supports reliable operation up to approximately 10 MHz in toggle-mode applications, assuming setup/hold margins and PCB trace delays are accounted for in layout.
Can 74HCT2G86GD,125 operate at 3.3 V supply?
No - the 74HCT variant is specified only for 4.5 V to 5.5 V operation. At 3.3 V, input thresholds (VIH ≥ 2.0 V) become non-compliant with standard 3.3 V CMOS levels, and output drive degrades significantly. For 3.3 V systems, use the 74LVC2G86 or 74AHC2G86 variants instead.
Does this device require external pull-up or pull-down resistors on unused inputs?
Yes - unused inputs must be terminated to VCC or GND. Floating TTL-compatible inputs can cause increased ICC, erratic output behavior, and elevated EMI due to intermediate voltage states. A 10 kΩ pull-up to VCC is recommended for unused A/B inputs to ensure defined HIGH logic state.
Is 74HCT2G86GD,125 qualified for automotive applications?
No - although rated for -40 °C to +125 °C, this part is not AEC-Q100 qualified and lacks automotive-specific testing (e.g., HTOL, ESD stress beyond HBM/C3). It is intended for industrial and commercial applications; automotive use requires explicit Nexperia automotive-grade equivalents such as 74HCT2G86DP/AZ.
