Product details
Overview
74AHC1G32GV-Q100 from Nexperia is a single 2-input OR gate IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with supply voltage range 2.0 V to 5.5 V, overvoltage-tolerant inputs up to 5.5 V, and CMOS-level input thresholds. It performs basic logic summation in powertrain control units, body electronics modules, and ADAS sensor interface circuits.
For engineers reviewing the 74AHC1G32GV-Q100 datasheet, 74AHC1G32GV-Q100 pinout, 74AHC1G32GV-Q100 application, or 74AHC1G32GV-Q100 equivalent, this page delivers verified functional identity, SC-74A (SOT753) package mapping, confirmed 5-pin terminal assignment, propagation delay ≤10.0 ns at 5.5 V/50 pF, and automotive-grade static/dynamic specifications per Rev. 5 (2024).
Technical Context
This device implements a single 2-input positive-logic OR function (Y = A + B) using advanced CMOS process technology. Its overvoltage-tolerant inputs enable level translation between 3.3 V and 5 V domains without external circuitry, and its symmetrical output impedance supports balanced rise/fall times under load.
It features latch-up immunity exceeding 100 mA per JESD78 Class II Level A, HBM ESD protection >2000 V, and CDM >1000 V. Input thresholds are CMOS-compatible (VIH = 3.85 V min at VCC = 5.5 V), ensuring robust noise rejection in electrically noisy automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input OR gate (Y = A OR B); enables compact discrete logic implementation in space-constrained ECUs. |
| Supply Voltage Range | 2.0 V to 5.5 V; supports dual-rail systems and brown-out resilience across automotive battery transients. |
| Operating Temperature | -40 °C to +125 °C; qualified per AEC-Q100 Grade 1 for under-hood and transmission control applications. |
| Propagation Delay | ≤7.0 ns at VCC = 5.5 V, CL = 15 pF; ensures timing-critical combinational logic meets real-time control deadlines. |
| Input Overvoltage Tolerance | Inputs withstand up to 5.5 V independent of VCC; eliminates need for external clamping diodes in mixed-voltage interfaces. |
| Output Drive Strength | ±8.0 mA at VCC = 4.5 V; sufficient to drive multiple 74-series inputs or small capacitive loads (<50 pF) directly. |
| Static Power Dissipation | ≤40 μA ICC max at VCC = 5.5 V; enables low-quiescent-current operation in always-on vehicle subsystems. |
Pinout & Package
74AHC1G32GV-Q100 uses the SC-74A (SOT753) surface-mount plastic package: 5-terminal, leadless outline with 1.1 mm × 0.9 mm body, 0.65 mm pitch, and GND on pin 3 for optimal thermal and signal return path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | B | Second logic input; accepts CMOS-level signals up to 5.5 V regardless of VCC value. |
| 2 | A | Primary logic input; electrically identical to pin 1; both inputs share same VIH/VIL thresholds. |
| 3 | GND | Ground reference (0 V); must be connected to system ground plane to ensure noise immunity and stable logic thresholds. |
| 4 | Y | OR output; provides rail-to-rail CMOS-compatible swing with symmetrical 2.4 kΩ typical output impedance. |
| 5 | VCC | Positive supply; powers internal logic and output stage; decoupling capacitor (100 nF) required within 5 mm. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from -40 °C to +125 °C ambient, including temperature cycling, HTOL, and ESD stress tests. |
| Overvoltage-tolerant inputs | Accepts 0–5.5 V input signals even when VCC = 2.0 V, enabling direct interfacing with higher-voltage sensors or legacy modules. |
| Low dynamic power dissipation | CPD = 16 pF; limits switching power to <1 μW at 1 MHz with 50 pF load, critical for thermally constrained modules. |
| High noise immunity | Input hysteresis not specified, but VIH/VIL margins exceed 1.5 V at VCC = 5.5 V, rejecting common-mode noise in 12 V systems. |
| Latch-up immunity | Exceeds 100 mA per JESD78 Class II Level A; prevents destructive parasitic SCR activation during transient overcurrent events. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74AHCT1G32GV-Q100 | TTL-compatible inputs (VIH = 2.0 V min), slightly higher propagation delay (≤9.0 ns @ 5.5 V/50 pF), identical package and temp range. | Required when interfacing with legacy 5 V TTL logic families; not suitable for pure CMOS systems with <2.0 V logic-high thresholds. | Select only if driving from 5 V TTL sources; otherwise prefer AHC version for lower power and wider VCC margin. |
| SN74LVC1G32DBVR | Non-automotive grade (industrial temp only), lower VCC range (1.65–5.5 V), higher drive (±32 mA), no AEC-Q100 qualification. | Acceptable for non-safety-critical infotainment or telematics modules where automotive qualification is not mandated. | Use only in non-AEC environments; lacks required reliability testing, lifetime data, and failure rate reporting for automotive deployment. |
Compared with 74AHCT1G32GV-Q100, the 74AHC1G32GV-Q100 offers tighter VIH/VIL margins for CMOS systems and lower ICC; versus SN74LVC1G32DBVR, it provides certified automotive reliability, extended temperature validation, and documented failure-in-time (FIT) rates - essential for ASIL-compliant designs.

FAQ
Is 74AHC1G32GV-Q100 pin-compatible with 74AHCT1G32GV-Q100?
Yes - both share identical SC-74A (SOT753) pinout: pin 1 = B, pin 2 = A, pin 3 = GND, pin 4 = Y, pin 5 = VCC. No PCB redesign is needed when substituting between AHC and AHCT variants, though input threshold compatibility must be verified per source logic family.
What is the maximum allowable output load capacitance for stable operation?
The datasheet specifies dynamic performance up to 50 pF (CL = 50 pF) with defined tpd and power dissipation. Operation beyond 50 pF is not characterized; excessive capacitance increases propagation delay nonlinearly and may cause output ringing or logic misinterpretation in high-speed paths.
Does this device require external pull-up or pull-down resistors on unused inputs?
No - unused inputs must be tied to VCC or GND to prevent floating states that increase ICC and risk oscillation. The device has no internal termination; leaving inputs unconnected violates recommended operating conditions and may cause unpredictable output behavior or elevated power consumption.
Can 74AHC1G32GV-Q100 operate reliably at 2.0 V supply with full functionality?
Yes - all parameters including VOH (≥1.5 V), VOL (≤0.5 V), and tpd (≤10.0 ns) are fully specified at VCC = 2.0 V across -40 °C to +125 °C, enabling use in ultra-low-voltage subsystems such as battery-backed memory retention circuits or energy-harvesting nodes.
