Product details
Overview
74HCT2G32DP-Q100 from Nexperia is a dual 2-input OR gate IC qualified to AEC-Q100 Grade 1 for automotive use, operating from -40 °C to +125 °C with TTL-compatible inputs, 4.5 V to 5.5 V supply range, and propagation delay of 13–36 ns at VCC = 4.5 V. It performs logic summation in body control modules, lighting drivers, and powertrain interface circuits.
For engineers reviewing the 74HCT2G32DP-Q100 datasheet, 74HCT2G32DP-Q100 pinout, 74HCT2G32DP-Q100 application, or 74HCT2G32DP-Q100 equivalent, this device supports high-noise-immunity digital signal combining in space-constrained automotive PCBs where input level compatibility with legacy TTL sources and guaranteed operation up to 125 °C are required.
Technical Context
This device implements two independent OR logic functions in a single TSSOP8 package, with inputs featuring clamp diodes enabling safe interfacing to voltages exceeding VCC when used with current-limiting resistors. Each gate has symmetrical input structure and rail-to-rail output swing capability under specified load conditions.
It operates within JEDEC JESD7A-compliant voltage ranges (4.5–5.5 V), meets HBM ESD >2000 V and CDM >1000 V requirements, and exhibits latch-up immunity exceeding 100 mA per JESD78 Class II Level B-critical for under-hood automotive environments subject to transients and thermal cycling.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Dual independent 2-input OR gate; enables compact implementation of Boolean sum operations without external gating. |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard automotive 5 V rail and ensures stable operation across battery voltage fluctuations. |
| Propagation Delay | 13–36 ns at VCC = 4.5 V - supports timing-critical signal routing in engine control and ADAS subsystems. |
| Input Compatibility | TTL-level inputs (VIH = 2.0 V min, VIL = 0.8 V max) - interoperable with legacy microcontrollers and discrete logic without level-shifting. |
| Operating Temperature | -40 °C to +125 °C - certified for under-hood placement including transmission control units and front-end modules. |
| Output Drive | ±4.0 mA at VCC = 4.5 V - sufficient to drive multiple CMOS/TTL inputs or small LED indicators directly. |
| Power Dissipation | CPD = 11 pF per buffer - enables accurate dynamic power estimation (PD = CPD × VCC² × fi × N) for thermal budgeting. |
Pinout & Package
TSSOP8 plastic thin shrink small outline package (SOT505-2); 8 leads; body width 3 mm; lead length 0.5 mm; pin 1 index located on lower left corner below marking code 'T32'.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1A | First OR gate input A - accepts TTL-level signals; clamped to prevent overvoltage damage. |
| 2 | 1B | First OR gate input B - electrically identical to 1A; supports parallel input routing. |
| 3 | 1Y | First OR gate output Y - delivers rail-to-rail CMOS-compatible logic levels with 4 mA sink/source capability. |
| 4 | GND | Ground reference - must be low-impedance connection to minimize noise coupling between gates. |
| 5 | 2A | Second OR gate input A - isolated from first gate; enables independent logic path implementation. |
| 6 | 2B | Second OR gate input B - shares same electrical specs as 1A/1B; no crosstalk between gates. |
| 7 | 2Y | Second OR gate output Y - identical output behavior to 1Y; supports dual-channel signal conditioning. |
| 8 | VCC | Positive supply - decoupling capacitor (100 nF) recommended adjacent to pin for transient suppression. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive applications requiring operation from -40 °C to +125 °C with full reliability testing. |
| TTL-compatible input thresholds | VIH ≥ 2.0 V and VIL ≤ 0.8 V at VCC = 4.5–5.5 V - eliminates need for external level translators when interfacing with older MCU families. |
| Input clamp diodes | Enables safe connection to voltages > VCC using series current-limiting resistors - critical for mixed-voltage sensor interfaces. |
| High noise immunity | Guaranteed 400 mV noise margin at VCC = 4.5 V - maintains logic integrity in electrically noisy engine compartments. |
| Low static current | ICC ≤ 1.0 μA typical at VCC = 5.5 V - reduces quiescent power in always-on vehicle modules like door controllers. |
Applications
| Body Control Module (BCM) | LED Lighting Driver Interface |
|---|---|
|
Use Scenario: Combining door-open, key-fob, and ignition status signals to trigger interior lighting activation. IC Role / Device Role / Timing Role: Dual OR gate performing real-time logical OR of three asynchronous inputs with sub-40 ns latency.

IC Role / Device Role / Timing Role: Low-power combiner driving an optocoupler input or microcontroller interrupt pin. Use Value: Reduces BOM count versus discrete transistor solutions while maintaining <1 μA standby current. |
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 |
|---|---|---|---|
| 74HCT2G32DC-Q100 | VSSOP8 package (SOT765-1); 2.3 mm body width vs. 3 mm TSSOP8; identical electrical specs. | Better suited for ultra-high-density layouts where board area is constrained beyond TSSOP8 footprint. | Select when PCB real estate is prioritized over hand-solderability or thermal mass requirements. |
| SN74LVC2G32QDCURQ1 | TI part; 1.65–5.5 V supply range; LVCMOS inputs; slightly higher ICC (10 μA max); same pinout. | Supports wider voltage scaling but lacks AEC-Q100 Grade 1 certification at +125 °C - rated only to +105 °C. | Choose only for non-under-hood applications where extended temperature range is not required. |
Compared with 74HCT2G32DC-Q100, the DP variant offers greater thermal mass and easier rework; versus SN74LVC2G32QDCURQ1, it provides guaranteed +125 °C operation and tighter VIH/VIL tolerances essential for robust automotive signal aggregation.

FAQ
What is the maximum allowable supply voltage for continuous operation?
The absolute maximum supply voltage is +7.0 V, but continuous operation must remain within the recommended range of 4.5 V to 5.5 V. Exceeding 5.5 V risks violating AEC-Q100 qualification limits and may degrade long-term reliability even if initial functionality appears normal.
Can 74HCT2G32DP-Q100 interface directly with 3.3 V logic outputs?
No - its TTL-compatible inputs require VIH ≥ 2.0 V minimum, but 3.3 V logic outputs typically meet this. However, VIL ≤ 0.8 V is guaranteed only up to VCC = 5.5 V; at 3.3 V supply, input thresholds shift and compatibility is not assured without level translation.
Does this device support hot insertion or live circuit connection?
No - it lacks explicit hot-swap protection features. Input clamp diodes provide limited overvoltage tolerance only when used with external current-limiting resistors; direct hot insertion into powered backplanes may exceed ±20 mA clamping current limits and cause permanent damage.
How does the propagation delay vary across temperature and voltage?
At VCC = 4.5 V, tpd ranges from 13 ns (25 °C) to 36 ns (-40 °C to +125 °C). Delay increases with decreasing temperature and supply voltage; worst-case specification (36 ns) is guaranteed across the full automotive temperature range and must be used for timing margin analysis.
