Product details
Overview
74AHC2G32DC-Q100 from Nexperia is a dual 2-input OR gate IC qualified to AEC-Q100 Grade 1, operating from -40 °C to +125 °C with supply voltage range 2.0–5.5 V, overvoltage-tolerant inputs up to 5.5 V, and CMOS-level input compatibility-used in automotive body control modules for discrete signal combination and fault-status aggregation.
For engineers reviewing the 74AHC2G32DC-Q100 datasheet, 74AHC2G32DC-Q100 pinout, 74AHC2G32DC-Q100 application, or 74AHC2G32DC-Q100 equivalent, this page delivers verified functional identity, automotive-grade thermal and voltage specs, VSSOP8 package layout, and validated logic-level alternatives for mixed-voltage signal routing in ADAS sensor interfaces and powertrain control units.
Technical Context
This device implements two independent OR logic functions (1A+1B→1Y; 2A+2B→2Y) with symmetrical output impedance and balanced propagation delays across temperature. Its overvoltage-tolerant inputs enable level translation between 3.3 V and 5 V domains without external circuitry.
Static thresholds are defined per supply: VIH = 3.85 V min at VCC = 5.5 V (CMOS), VOL ≤ 0.55 V at IO = 8.0 mA, and tpd = 3.2–7.0 ns depending on VCC and load capacitance-ensuring deterministic timing in safety-critical automotive combinatorial logic paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input OR gate - enables parallel Boolean OR operations for status merging or fault detection. |
| Supply Voltage Range | 2.0–5.5 V - supports direct integration into 3.3 V microcontroller I/O domains and 5 V legacy subsystems. |
| Operating Temperature | -40 °C to +125 °C - meets AEC-Q100 Grade 1 requirements for under-hood and cabin electronics. |
| Input Voltage Tolerance | Up to 5.5 V regardless of VCC - allows safe interfacing with higher-voltage signals without clamping diodes. |
| Propagation Delay | 3.2 ns (typ) at VCC = 5.0 V, CL = 15 pF - ensures sub-10 ns timing margins for real-time diagnostic response. |
| Output Drive Strength | ±8.0 mA at VCC = 4.5 V - sufficient to drive multiple CMOS inputs or small capacitive loads directly. |
| Power Dissipation | 250 mW max at Tamb ≤ 99 °C (VSSOP8) - enables compact placement in thermally constrained ECUs. |
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, 5 (1A, 2A) | Data input A for Gate 1 and Gate 2 | Accepts CMOS-level signals; overvoltage tolerant to 5.5 V independent of VCC. |
| 2, 6 (1B, 2B) | Data input B for Gate 1 and Gate 2 | Second OR operand per gate; identical electrical characteristics to 1A/2A. |
| 3, 7 (2Y, 1Y) | Data output Y for Gate 2 and Gate 1 | Active-high OR result; symmetrical rise/fall times support clean signal edges. |
| 4 | GND | Ground reference (0 V); must be low-impedance connection for noise immunity. |
| 8 | VCC | Primary supply rail; decoupling capacitor required within 10 mm for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use up to +125 °C ambient, including thermal cycling and humidity testing. |
| Overvoltage-tolerant inputs | Inputs withstand 5.5 V even when VCC = 2.0 V - eliminates need for external level shifters in mixed-rail systems. |
| Low dynamic power dissipation | CPD = 16 pF per buffer - reduces switching current and EMI in high-frequency control logic. |
| High noise immunity | VIL = 1.65 V max, VIH = 3.85 V min at VCC = 5.5 V - provides >1.3 V noise margin in noisy automotive environments. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A - prevents destructive latch-up during transient overvoltage events. |
Applications
| Body Control Module (BCM) | Advanced Driver Assistance Systems (ADAS) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT2G32DC-Q100 | TTL-compatible inputs (VIH = 2.0 V min), otherwise identical pinout, package, and AEC-Q100 qualification. | Required where interfacing with legacy 5 V TTL outputs; not suitable for pure CMOS 3.3 V systems without level adaptation. | Select when driving from 5 V TTL sources; verify input threshold compatibility with upstream driver VOH. |
| SN74LVC2G32QDCURQ1 | TI's AEC-Q100 Grade 1 dual OR gate; wider VCC range (1.65–5.5 V); lower ICC (max 10 μA vs 40 μA). | Supports 1.8 V logic domains; tighter VOL (0.55 V vs 0.55 V) but same drive strength; different pinout (pin 1 = 1A, pin 2 = GND). | Choose for multi-voltage designs needing 1.8 V compatibility; requires PCB redesign due to non-pin-compatible layout. |
Compared with 74AHCT2G32DC-Q100, the TTL-input variant trades CMOS noise margin for legacy interface support; versus SN74LVC2G32QDCURQ1, the Nexperia part offers superior high-temperature static performance above 105 °C and proven field reliability in engine bay deployments.

FAQ
What is the maximum allowable input voltage when VCC = 2.0 V?
The 74AHC2G32DC-Q100 supports overvoltage-tolerant inputs up to 5.5 V regardless of VCC level. When VCC = 2.0 V, inputs may safely reach 5.5 V without damage or functional disruption-enabling direct connection to 5 V sensor outputs or communication lines in mixed-voltage automotive subsystems.
Does this device support 1.8 V logic levels?
No. The 74AHC2G32DC-Q100 is specified for VCC = 2.0–5.5 V and requires minimum VIH = 1.5 V at VCC = 2.0 V, making it incompatible with standard 1.8 V logic families. For 1.8 V operation, consider SN74LVC2G32QDCURQ1 or similar LVC-series devices explicitly rated down to 1.65 V.
How does the VSSOP8 package compare thermally to TSSOP8?
The VSSOP8 (SOT765-1) has a lower thermal resistance than TSSOP8 (SOT505-2): Ptot derates at 4.9 mW/K above 99 °C versus 4.6 mW/K above 96 °C. This gives the VSSOP8 slightly better sustained power handling at high ambient temperatures typical in engine compartments, though both meet AEC-Q100 Grade 1 thermal requirements.
Is there a pin-compatible 74AHC2G32 variant with different temperature grading?
No. All 74AHC2G32-Q100 variants-including DP (TSSOP8) and DC (VSSOP8)-are exclusively qualified to AEC-Q100 Grade 1 (-40 °C to +125 °C). Non-automotive versions (e.g., 74AHC2G32DP, 74AHC2G32DC) are rated only to +85 °C and lack automotive qualification documentation, test reports, or traceability.
