Product details
Overview
74HCT2G86DP-Q100 from Nexperia is an automotive-grade dual 2-input XOR gate in TSSOP8 (SOT505-2) package, operating from 4.5 V to 5.5 V with TTL-compatible inputs, 11 ns typical propagation delay at 4.5 V, and AEC-Q100 Grade 1 qualification (-40 °C to +125 °C). It performs logic comparison and signal parity generation in body control modules and powertrain interface circuits.
For engineers reviewing the 74HCT2G86DP-Q100 datasheet, 74HCT2G86DP-Q100 pinout, 74HCT2G86DP-Q100 application, or 74HCT2G86DP-Q100 equivalent, this device supports high-noise automotive environments, requires no level-shifting for 5 V microcontroller interfaces, and delivers predictable timing behavior under temperature extremes.
Technical Context
This device implements two independent CMOS-based XOR gates with TTL-level input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), enabling direct interfacing with legacy 5 V logic families. Each gate exhibits symmetrical propagation delay (tPLH ≈ tPHL) and transition times (tTLH ≈ tTHL).
Input clamp diodes allow safe operation with input voltages exceeding VCC when used with current-limiting resistors. The design meets JESD7A (2.0–6.0 V) and JESD8C (2.7–3.6 V) standards and achieves HBM ESD robustness >2000 V and CDM >1000 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input exclusive-OR (XOR); outputs HIGH only when inputs differ - enables parity checking and signal inversion control. |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard 5 V automotive rail; avoids need for external regulators or level shifters. |
| Propagation Delay | 11 ns typ (VCC = 4.5 V, CL = 50 pF) - ensures deterministic timing in safety-critical bus arbitration and sensor signal conditioning. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - guarantees reliable recognition of TTL logic levels without external biasing. |
| Operating Temperature | -40 °C to +125 °C - validated for under-hood and transmission control unit environments per AEC-Q100 Grade 1. |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive multiple CMOS inputs or small LED indicators directly. |
| Power Dissipation | CPD = 9 pF per buffer - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal budgeting. |
Pinout & Package
TSSOP8 package (SOT505-2): plastic thin shrink small outline, 8 leads, 3 mm body width, 0.5 mm lead length, exposed pad not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First XOR gate input A - accepts TTL-level signals; clamped to prevent overvoltage damage. |
| 2 | VCC | Positive supply rail - must be decoupled locally with 100 nF ceramic capacitor near pin 2. |
| 3 | 1B | First XOR gate input B - electrically identical to pin 1; differential pair forms first logic cell. |
| 4 | 1Y | First XOR gate output Y - drives downstream logic or analog comparators; fan-out limited by 4 mA sink/source. |
| 5 | 2Y | Second XOR gate output Y - independent of first gate; shares no internal nodes with pins 1–4. |
| 6 | 2B | Second XOR gate input B - isolated from first gate; supports concurrent dual-bit comparison. |
| 7 | GND | Ground reference - must connect to low-impedance system ground plane to maintain noise immunity. |
| 8 | 2A | Second XOR gate input A - completes second logic cell; pin order follows IEC-standard functional diagram. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use across -40 °C to +125 °C ambient, including thermal cycling and humidity testing. |
| TTL-compatible input thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 4.5–5.5 V supply - eliminates need for external level translators with 5 V MCUs. |
| Input clamp diodes | Enable safe interface to voltages > VCC using series current-limiting resistors - critical for mixed-rail diagnostics. |
| High noise immunity | CMOS architecture with >40 % noise margin at VCC = 5 V - suppresses coupling from ignition or motor drivers. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during load dump transients. |
Applications
| Body Control Module (BCM) | Engine Control Unit (ECU) Interface |
|---|---|
|
Use Scenario: Detecting mismatch between redundant door lock status sensors to trigger fault reporting. IC Role / Device Role / Timing Role: Dual XOR compares two independent sensor outputs; each gate operates asynchronously with sub-12 ns latency. Use Value: Enables real-time hardware-level fault detection without MCU intervention, reducing ASIL-B software overhead. |
Use Scenario: Validating consistency between crankshaft and camshaft position signals before fuel injection enable. IC Role / Device Role / Timing Role: XOR gate acts as a hardware comparator; output toggles only when signals disagree - triggers immediate diagnostic flag. Use Value: Provides deterministic, zero-software-latency validation critical for ISO 26262 ASIL-C timing requirements. |
| Transmission Control Unit (TCU) | Automotive Infotainment Bus Arbiter |
|
Use Scenario: Monitoring gear selector switch redundancy by comparing mechanical and Hall-effect sensor outputs. IC Role / Device Role / Timing Role: One XOR gate computes parity across two sensor streams; output feeds watchdog timer input. Use Value: Delivers fail-safe sensor validation with <15 ns worst-case delay - meets TCU functional safety timing constraints. |
Use Scenario: Resolving contention between two display controller units sharing a single SPI bus line. IC Role / Device Role / Timing Role: XOR generates bus grant signal when controllers request access simultaneously - resolves priority in hardware. Use Value: Eliminates arbitration firmware delays and race conditions, ensuring deterministic bus handover in <20 ns. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual XOR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HCT2G86DC-Q100 | VSSOP8 (SOT765-1) package, 2.3 mm body width, identical electrical specs. | Higher board density; requires finer pitch routing and reflow profile adjustment. | Select when PCB space is constrained and assembly process supports 0.5 mm pitch. |
| SN74LVC2G86QDCURQ1 | TI part: 1.65–5.5 V supply, lower VIH (1.7 V min), 3.5 ns faster tpd at 3.3 V, different pinout (1A/1B/GND/1Y/2A/2B/VCC/2Y). | Better suited for mixed-voltage 3.3 V systems; not pin-compatible - requires layout revision. | Choose for 3.3 V domains or when sub-8 ns propagation is required; verify pin mapping before redesign. |
Compared with 74HCT2G86DC-Q100, the DP variant offers easier hand-soldering and thermal relief via larger TSSOP pads; versus SN74LVC2G86QDCURQ1, it provides guaranteed 5 V TTL compatibility but trades off speed and voltage flexibility for AEC-Q100-aligned robustness at 5 V.

FAQ
What is the maximum clock frequency supported by the 74HCT2G86DP-Q100?
The device does not operate as a clocked sequential circuit but as a combinational logic gate. Its usable toggle rate is determined by propagation delay and transition time: with tpd = 11 ns typ and tt = 6 ns typ at 4.5 V, it reliably supports input signal transitions up to approximately 30 MHz in non-critical timing paths. For synchronous applications, ensure setup/hold margins exceed 15 ns.
Can the 74HCT2G86DP-Q100 interface directly with 3.3 V microcontrollers?
No - its TTL input thresholds (VIH ≥ 2.0 V, VIL ≤ 0.8 V) are optimized for 5 V systems. A 3.3 V MCU may not guarantee valid HIGH recognition due to insufficient noise margin. Use a level translator such as TXS0102 or select SN74LVC2G86QDCURQ1 for native 3.3 V compatibility.
Does the 74HCT2G86DP-Q100 include ESD protection on all pins?
Yes - it features integrated HBM ESD protection exceeding 2000 V and CDM protection exceeding 1000 V on all I/O pins, verified per ANSI/ESDA/JEDEC JS-001 and JS-002 standards. No external TVS diodes are required for standard handling or board-level ESD events.
Is the 74HCT2G86DP-Q100 pin-compatible with the 74HC2G86DP-Q100?
Yes - both share identical TSSOP8 (SOT505-2) pinout and footprint. The key difference is input threshold: HC version uses CMOS thresholds (VIH = 3.15 V min at 4.5 V), while HCT uses TTL thresholds (VIH = 2.0 V min). Swapping requires verifying source logic family compatibility.
