Product details
Overview
74HCT2G32DC-Q100 from Nexperia is a dual 2-input OR gate logic IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with 4.5 V to 5.5 V supply, TTL-compatible inputs, and propagation delay of 13–36 ns at VCC = 4.5 V - used in vehicle body control modules for discrete signal combination.
For engineers reviewing the 74HCT2G32DC-Q100 datasheet, 74HCT2G32DC-Q100 pinout, 74HCT2G32DC-Q100 application, or 74HCT2G32DC-Q100 equivalent, this device supports high-noise-immunity digital logic interfacing in engine management, lighting control, and power distribution systems where TTL-level compatibility and automotive-grade reliability are required.
Technical Context
This device implements two independent OR gates in a single VSSOP8 package, each with true TTL input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V) and rail-to-rail CMOS outputs capable of sourcing/sinking ±4.0 mA. Input clamp diodes allow safe interfacing to voltages exceeding VCC when used with current-limiting resistors.
Its static and dynamic behavior is characterized across full automotive temperature range: VOH ≥ 4.18 V and VOL ≤ 0.26 V at IO = ±4.0 mA, tPD = 13–36 ns, and CPD = 11 pF per buffer - enabling predictable timing in combinatorial logic paths within ASIL-B-relevant subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual 2-input OR gate - performs Boolean OR on two independent input pairs (1A/1B→1Y, 2A/2B→2Y) |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard automotive 5 V rail with ±10% tolerance margin |
| Input Logic Type | TTL-compatible - accepts 2.0 V min HIGH and 0.8 V max LOW, enabling direct interface with legacy microcontrollers |
| Propagation Delay | 13–36 ns at VCC = 4.5 V - ensures sub-40 ns worst-case path delay for real-time signal conditioning |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive multiple 74-series inputs or small LED indicators without buffering |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood and cabin-mounted automotive ECUs |
| AEC-Q100 Grade | Grade 1 - certified for automotive applications per AEC-Q100 Rev G requirements |
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 OR gate input A - active-high logic input with TTL threshold and internal clamp diode |
| 2 | 1B | First OR gate input B - identical electrical characteristics to Pin 1; both inputs share same VIH/VIL specs |
| 3 | 1Y | First OR gate output Y - CMOS push-pull output, rail-to-rail swing, ±4.0 mA drive capability |
| 4 | GND | Ground reference - common return path for all internal circuitry and I/O; must be low-impedance |
| 5 | 2A | Second OR gate input A - electrically isolated from first gate; identical to Pin 1 |
| 6 | 2B | Second OR gate input B - identical to Pin 2; enables independent dual-gate operation |
| 7 | 2Y | Second OR gate output Y - fully buffered output matching Pin 3 performance and loading behavior |
| 8 | VCC | Positive supply - powers both gates; requires local 100 nF ceramic decoupling adjacent to Pin 8 |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use up to +125 °C ambient, including HTOL, TC, and ESD stress testing per Rev G |
| TTL-compatible input thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 4.5–5.5 V - eliminates need for level-shifting when interfacing with 5 V microcontrollers |
| Input clamp diodes | Enable safe connection to signals up to VCC + 0.5 V using external current-limiting resistors - protects against overvoltage transients |
| High noise immunity | Typical noise margin > 1.2 V at VCC = 5 V - suppresses false triggering from EMI in vehicle harness environments |
| Low static power consumption | ICC ≤ 20 μA at VCC = 5.5 V and TA = +125 °C - minimizes quiescent load on battery-backed domains |
Applications
| Body Control Module (BCM) | Headlamp Control Unit |
|---|---|
Use Scenario: Combining door-open and ignition-on signals to enable interior lighting only when both conditions are met. IC Role / Device Role / Timing Role: Dual OR gate performing real-time logical OR of two independent sensor inputs with sub-40 ns latency.

Use Scenario: Detecting any fault condition (overcurrent, short, open-load) across four motor drivers to trigger main relay shutdown. IC Role / Device Role / Timing Role: Fault-or logic block aggregating four independent fault flags into a single system-alert signal. Use Value: Enables deterministic, hardware-based safety reaction within <50 ns - critical for ISO 26262 ASIL-B compliance. |
Use Scenario: Combining seat forward/reverse switch signals with memory recall button to initiate position adjustment sequence. IC Role / Device Role / Timing Role: Input gating logic that validates user intent before enabling motor control path. Use Value: Prevents unintended actuation due to contact bounce or EMI by requiring clean, synchronized input assertion. |
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 |
|---|---|---|---|
| 74HC2G32DC-Q100 | CMOS input thresholds (VIH = 3.15 V min at VCC = 4.5 V); higher noise margin but incompatible with TTL sources | Requires 3.3 V or CMOS-compatible drivers; unsuitable for direct interface with legacy 5 V TTL outputs | Select when interfacing with modern low-voltage MCUs and noise-sensitive environments where higher VIH improves immunity |
| SN74LVC2G32DBVR | 3.3 V only (1.65–5.5 V), LVTTL-compatible, lower tPD (3.5 ns typ), non-automotive qualified | Lacks AEC-Q100 qualification; not approved for production automotive ECUs despite similar pinout | Use only in non-safety-critical prototyping or industrial control where automotive qualification is not mandated |
Compared with 74HC2G32DC-Q100 and SN74LVC2G32DBVR, the 74HCT2G32DC-Q100 uniquely delivers TTL-level compatibility *and* AEC-Q100 Grade 1 certification in VSSOP8 - making it the only drop-in solution for upgrading legacy 5 V automotive logic without redesigning input drive stages or qualifying new components.

FAQ
What is the maximum supply voltage for 74HCT2G32DC-Q100?
The absolute maximum supply voltage is +7.0 V per IEC 60134 limiting values, but the recommended operating range is strictly 4.5 V to 5.5 V. Operation above 5.5 V voids AEC-Q100 qualification and risks parametric shift or latch-up, even if within absolute limits.
Does 74HCT2G32DC-Q100 support mixed-voltage interfacing?
Yes - its input clamp diodes allow connection to signals up to VCC + 0.5 V when used with appropriate series current-limiting resistors. For example, with VCC = 5.0 V, inputs can safely accept 5.5 V signals, provided IIK remains within ±20 mA.
How does the VSSOP8 package affect thermal performance?
The SOT765-1 VSSOP8 package has a thermal resistance θJA of approximately 204 K/W (per datasheet derating curve), meaning it dissipates up to 250 mW at +99 °C ambient before derating begins. At typical logic loads (<1 mW static), junction temperature rise remains negligible in automotive enclosures.
Can 74HCT2G32DC-Q100 drive an LED directly?
Yes - with VCC = 5.0 V and a 220 Ω series resistor, the output can sink 4.0 mA while maintaining VOL ≤ 0.26 V, producing ~12 mA LED current. However, sustained DC drive is discouraged; use pulsed operation or add a transistor stage for reliability in automotive life-cycle testing.
