Product details
Overview
74VHCT32PW-Q100 from Nexperia is an automotive-qualified quad 2-input OR gate in TSSOP14 package, operating at 4.5 V to 5.5 V supply with TTL-compatible inputs, 7.0 ns typical propagation delay (CL = 15 pF), and AEC-Q100 Grade 1 qualification for under-hood control logic.
For engineers reviewing the 74VHCT32PW-Q100 datasheet, 74VHCT32PW-Q100 pinout, 74VHCT32PW-Q100 application, or 74VHCT32PW-Q100 equivalent, key selection criteria include input voltage compatibility (TTL-level), guaranteed operation up to +125 °C, balanced propagation delays across all four gates, Schmitt-trigger input hysteresis, and side-wettable flank packaging for AOI-capable solder joint inspection.
Technical Context
This device implements four independent 2-input OR logic functions using high-speed Si-gate CMOS technology, pin-compatible with LSTTL but with CMOS power efficiency. It features Schmitt-trigger inputs for noise immunity and accepts input voltages exceeding VCC, enabling robust interfacing in mixed-voltage automotive subsystems.
Each gate operates with identical electrical characteristics: VIH = 2.0 V min (TTL-compatible), VIL = 0.8 V max, VOH ≥ 3.70 V at IO = –8.0 mA, and VOL ≤ 0.55 V at IO = 8.0 mA over –40 °C to +125 °C ambient range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input OR gate - four independent OR operations per package, no internal interconnect. |
| Supply Voltage Range | 4.5 V to 5.5 V - supports stable operation across automotive battery variations including cold-crank transients. |
| Propagation Delay | 7.0 ns typ (CL = 15 pF, VCC = 5.0 V) - enables timing-critical combinatorial logic in body control modules. |
| Input Compatibility | TTL-level inputs (VIH ≥ 2.0 V, VIL ≤ 0.8 V) - interoperable with legacy microcontrollers and discrete logic without level-shifting. |
| Temperature Range | –40 °C to +125 °C - qualified for engine bay and transmission control unit mounting locations. |
| AEC-Q100 Grade | Grade 1 - certified for automotive applications requiring full temperature range reliability and stress testing compliance. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - withstands handling and assembly ESD events in Tier 1 manufacturing environments. |
Pinout & Package
TSSOP14 package (SOT402-1): plastic thin shrink small outline, 14 leads, 4.4 mm body width, side-wettable flanks for automated optical inspection of solder joints.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 4, 9, 12 | 1A, 2A, 3A, 4A | First input of each OR gate - electrically isolated; accepts TTL or CMOS logic levels. |
| 2, 5, 10, 13 | 1B, 2B, 3B, 4B | Second input of each OR gate - Schmitt-triggered for noise rejection on noisy automotive buses. |
| 3, 6, 8, 11 | 1Y, 2Y, 3Y, 4Y | Output of each OR gate - drives standard CMOS loads up to 8 mA sink/source capability. |
| 7 | GND | Ground reference (0 V) - must be connected to system ground plane for signal integrity and EMI control. |
| 14 | VCC | Positive supply rail - decoupling capacitor (100 nF ceramic) required within 5 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Schmitt-trigger inputs | Provides hysteresis (typically 0.3 V) to reject fast transient noise on sensor or switch inputs in vehicle cabins. |
| Input voltage tolerance | Accepts VI up to 7.0 V - allows direct connection to 5 V or 12 V auxiliary signals without external clamping. |
| Side-wettable flanks | Enables automated optical inspection of solder fillets on bottom-side terminals - critical for zero-defect automotive PCBA requirements. |
| Low ICC quiescent current | Max 40 μA at VCC = 5.5 V - minimizes standby power in always-on vehicle modules like door lock controllers. |
| Pin-compatible with LSTTL | Direct replacement for 74LS32 in legacy designs - preserves PCB layout while upgrading to CMOS power efficiency and noise immunity. |
Applications
| Body Control Module Logic | Powertrain Sensor Interface |
|---|---|
|
Use Scenario: Combining door ajar, window position, and mirror fold status signals into a single wake-up request line for low-power MCU. IC Role / Device Role / Timing Role: Combinatorial OR gate aggregating multiple mechanical switch inputs into one interrupt-enable signal. Use Value: Eliminates need for software polling or additional GPIOs; deterministic sub-10 ns response ensures immediate MCU wake-up on any event. |
Use Scenario: Detecting fault conditions across multiple engine sensors (MAP, IAT, ECT) where any single out-of-range reading triggers safety shutdown. IC Role / Device Role / Timing Role: Hardware-level fault-or logic block feeding directly to engine control unit's fail-safe input. Use Value: Bypasses software latency; guarantees <10 ns reaction time to sensor faults, meeting ISO 26262 ASIL-B timing constraints. |
| Infotainment Power Sequencing | ADAS Camera Power Enable |
|
Use Scenario: Enabling main infotainment SoC power rail when either ignition ON or accessory mode is active. IC Role / Device Role / Timing Role: OR gate combining two independent vehicle bus-derived enable signals to generate unified power-on command. Use Value: Ensures reliable boot sequence initiation regardless of ignition switch position - eliminates race conditions in multi-rail power sequencing. |
Use Scenario: Activating camera module power only when both ADAS domain controller is awake and vehicle speed exceeds 5 km/h. IC Role / Device Role / Timing Role: Final hardware OR gate in power enable chain, overriding software control during emergency vision activation. Use Value: Provides fail-operational behavior: if software hangs, hardwired OR path maintains forward camera operation during collision avoidance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar quad 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74VHC32PW-Q100 | CMOS-level inputs (VIH ≥ 3.85 V @ VCC = 5.5 V); wider VCC range (2.0–5.5 V) | Better suited for mixed-voltage domains with 3.3 V controllers; not TTL-compatible | Select when interfacing with 3.3 V MCUs or when lower static power (<2.0 μA) is prioritized over TTL compatibility. |
| SN74LVC32APWRE4 | 3.3 V only (1.65–3.6 V), higher drive strength (24 mA), no AEC-Q100 Grade 1 certification | Limited to cabin electronics; requires level-shifting for 5 V systems | Choose for cost-sensitive non-engine-bay applications where AEC-Q100 is not mandated and 3.3 V operation suffices. |
Compared with 74VHC32PW-Q100 and SN74LVC32APWRE4, the 74VHCT32PW-Q100 uniquely delivers TTL-level input compatibility at 5 V with full automotive qualification - making it the only option for drop-in replacement of legacy 74LS32 in AEC-Q100-compliant engine control units.

FAQ
Is 74VHCT32PW-Q100 compatible with 3.3 V microcontrollers?
No - the 74VHCT32PW-Q100 requires VCC = 4.5 V to 5.5 V and has TTL-level inputs (VIH ≥ 2.0 V), but its outputs swing to near-VCC (≥3.7 V at 5 V). Direct interface with 3.3 V MCUs risks overvoltage damage unless level-shifting or series resistors are used. For 3.3 V systems, consider the 74VHC32PW-Q100 variant instead.
Does this part support hot-swap or live-insertion?
No - the device lacks hot-swap protection circuitry. Applying VCC before GND, or vice versa, may cause latch-up due to internal parasitic SCR structures. Always ensure proper power sequencing: GND connected first, then VCC, followed by input signals. Use external series resistors on inputs if hot-plug risk exists.
What is the significance of "Side-Wettable Flanks" in the TSSOP14 package?
Side-wettable flanks refer to exposed metal on the vertical edges of the TSSOP14 leads, enabling automated optical inspection (AOI) systems to verify solder fillet formation and wetting quality on reflowed joints. This feature is mandated by many Tier 1 automotive suppliers for zero-defect PCBA acceptance.
Can unused gates be left floating?
No - all unused inputs must be tied to VCC or GND. Floating CMOS inputs cause increased ICC, unpredictable logic states, and potential oscillation due to noise coupling. Unused outputs may be left open, but tying unused inputs prevents shoot-through current and ensures predictable quiescent behavior across temperature.
