Product details
Overview
74HC1G32GV-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 6.0 V, CMOS input levels, and symmetrical output impedance. It implements basic Boolean OR logic in compact SC-74A (SOT753) packaging for space-constrained vehicle control modules.
For engineers reviewing the 74HC1G32GV-Q100 datasheet, 74HC1G32GV-Q100 pinout, 74HC1G32GV-Q100 application, or 74HC1G32GV-Q100 equivalent, this device serves as a low-power, high-noise-immunity logic gate for automotive body electronics, powertrain interface circuits, and infotainment system signal conditioning where rail-to-rail compatibility and latch-up immunity (>100 mA) are required.
Technical Context
This device implements a single 2-input positive-logic OR function (Y = A + B) using standard CMOS process technology. Its inputs include integrated clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors.
It supports dual-voltage operation across 2.0 V–6.0 V while maintaining defined VIH/VIL thresholds and delivers balanced tPLH/tPHL propagation delays - 8 ns typical at VCC = 4.5 V and CL = 50 pF - with low dynamic power dissipation (CPD = 19 pF).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Single 2-input OR gate (Y = A OR B), positive-logic implementation |
| Supply Voltage Range | 2.0 V to 6.0 V - enables interoperability with 3.3 V and 5.0 V subsystems without level shifters |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood and transmission-control applications |
| Propagation Delay | 8 ns typical (VCC = 4.5 V, CL = 50 pF) - ensures timing predictability in synchronous logic paths |
| Input Clamping | Integrated input clamp diodes - allows safe overvoltage input handling up to ±20 mA with external resistors |
| ESD Robustness | HBM > 2000 V, CDM > 1000 V - meets automotive ESD immunity requirements per JS-001/JS-002 |
| Latch-up Immunity | Exceeds 100 mA per JESD78 Class II Level B - prevents destructive latch-up during transient events |
Pinout & Package
SC-74A (SOT753) plastic surface-mounted package: 5-terminal, 1.1 × 0.9 × 0.46 mm body, leadless edge-terminal construction with gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (B) | Data input B | CMOS-level input accepting 0 V to VCC; includes internal clamp diode to VCC and GND |
| 2 (A) | Data input A | CMOS-level input identical to Pin 1; supports wired-OR expansion when combined with external pull-ups |
| 3 (GND) | Ground reference | 0 V return path for all internal circuitry and I/O; must be low-impedance for noise immunity |
| 4 (Y) | Data output Y | Push-pull CMOS output sourcing/sinking ±12.5 mA; rail-to-rail swing with VOH ≥ 4.13 V @ 2.0 mA (VCC = 4.5 V) |
| 5 (VCC) | Supply voltage | Primary power rail; decoupling capacitor (100 nF) recommended within 5 mm of this pin |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use across -40 °C to +125 °C ambient, including temperature cycling and HTOL stress |
| Symmetrical output impedance | Matched rise/fall drive strength ensures consistent signal edge rates and reduced skew in timing-critical paths |
| High noise immunity | VIH/VIL margins exceed 30% of VCC across full voltage range - suppresses false triggering from coupled transients |
| Low static power consumption | ICC ≤ 20 μA max at VCC = 6.0 V - enables always-on functions in battery-sensitive modules |
| Wide VCC tolerance | Functional operation guaranteed from 2.0 V (e.g., brown-out detection) to 6.0 V (e.g., alternator surge conditions) |
Applications
| Body Control Module (BCM) | Engine Control Unit (ECU) Interface |
|---|---|

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 |
|---|---|---|---|
| 74HCT1G32GV-Q100 | TTL-compatible inputs (VIH = 2.0 V min @ VCC = 4.5–5.5 V); otherwise identical pinout, package, and speed | Required when interfacing legacy 5 V TTL logic or microcontrollers with non-CMOS output drivers | Select when driving from 5 V TTL sources; avoid if interfacing 3.3 V CMOS-only systems due to higher VIH threshold |
| SN74LVC1G32DBVR | Lower VCC range (1.65–5.5 V), LVC logic family, slightly faster tpd (5.5 ns typ @ 3.3 V), no AEC-Q100 qualification | Acceptable for non-automotive industrial or consumer applications requiring wider low-voltage support | Use only in non-automotive designs; not suitable for AEC-Q100-compliant programs due to lack of qualification and temperature rating |
Compared with 74HC1G32GV-Q100, the 74HCT1G32GV-Q100 offers direct TTL input compatibility but sacrifices 2.0 V minimum supply capability, while SN74LVC1G32DBVR provides better low-voltage performance but lacks automotive qualification and high-temperature operation - making the original part uniquely suited for AEC-Q100-compliant 2.0–6.0 V automotive logic interfacing.

FAQ
What is the maximum allowable supply voltage for continuous operation?
The absolute maximum supply voltage is +7.0 V per IEC 60134 limiting values, but recommended continuous operation is limited to 6.0 V. Exceeding 6.0 V risks accelerated parametric drift and reduced long-term reliability, even if clamping currents remain within ±20 mA limits.
Can this device interface directly with 3.3 V microcontroller GPIOs?
Yes - its CMOS input thresholds scale with VCC, so at VCC = 3.3 V, VIH ≈ 2.3 V and VIL ≈ 1.0 V, fully compatible with standard 3.3 V CMOS outputs. No level-shifting circuitry is needed when VCC matches the MCU's I/O voltage.
Does the SC-74A (SOT753) package support automated optical inspection (AOI)?
Yes - the SOT753 package has gull-wing leads with defined coplanarity (≤0.10 mm) and solderable side terminations, enabling reliable AOI detection of solder joint quality, bridging, and component placement offset per IPC-A-610 Class 2/3 standards.
How does input clamping affect external resistor selection?
When interfacing to voltages > VCC, a series current-limiting resistor must restrict input current to ≤±20 mA. For example, connecting a 12 V signal to VCC = 5 V requires R ≥ (12 V − 5.5 V)/20 mA = 325 Ω to stay within clamp diode rating and prevent thermal overstress.
