Product details
Overview
74VHCT32D-Q100 from Nexperia is a quad 2-input OR gate IC designed for automotive signal logic combining, compliant with AEC-Q100 Grade 1, operating from −40 °C to +125 °C, with TTL-compatible input thresholds (VIH = 2.0 V min, VIL = 0.8 V max at VCC = 4.5–5.5 V), 7.0 ns typical propagation delay (CL = 15 pF, VCC = 5 V), and SO14 (SOT108-1) package.
For engineers reviewing the 74VHCT32D-Q100 datasheet, 74VHCT32D-Q100 pinout, 74VHCT32D-Q100 application, or 74VHCT32D-Q100 equivalent, this device serves as a drop-in logic-level combiner in engine control units, body electronics, and ADAS sensor interface subsystems where robustness across extended temperature and noise immunity are required.
Technical Context
The 74VHCT32D-Q100 implements four independent 2-input OR gates using high-speed Si-gate CMOS technology, pin-compatible with LSTTL, with Schmitt-trigger inputs enabling noise rejection on slow-rising signals. Its input voltage tolerance exceeds VCC, supporting mixed-voltage interfacing without level shifters.
It operates under JEDEC standard No. 7-A and meets AEC-Q100 Grade 1 qualification, specifying guaranteed functionality over −40 °C to +125 °C ambient, with static VIH/VIL thresholds fixed for TTL logic families and dynamic tpd < 9.0 ns (max) at 5 V/50 pF load.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input OR gate - provides four independent Boolean OR operations per package. |
| Supply Voltage (VCC) | 4.5 V to 5.5 V - ensures compatibility with standard 5 V automotive power rails and margin against ripple. |
| Input Thresholds | VIH ≥ 2.0 V, VIL ≤ 0.8 V - matches TTL logic families, enabling direct interface with legacy microcontrollers and sensors. |
| Propagation Delay (tpd) | Max 9.0 ns at VCC = 5 V, CL = 50 pF - supports reliable timing in sub-100 MHz combinational paths. |
| Operating Temperature | −40 °C to +125 °C - qualified for under-hood and powertrain applications per AEC-Q100 Grade 1. |
| ESD Protection | HBM > 2000 V, CDM > 1000 V - mitigates assembly- and field-induced electrostatic damage in automotive manufacturing. |
| Output Drive | ±8.0 mA at VCC = 4.5 V - sufficient to drive multiple 74-series inputs or small capacitive loads without buffering. |
Pinout & Package
74VHCT32D-Q100 uses the SO14 plastic small outline package (SOT108-1), 14-lead, 3.9 mm body width, with gull-wing leads and standard 1.27 mm pitch. Pin 1 index located at top-left corner with notch or dot marking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A (Pins 1, 4, 9, 12) | Input A of Gate n | First input terminal for each of the four OR gates; accepts TTL- or CMOS-level signals up to VCC + 0.5 V. |
| 1B, 2B, 3B, 4B (Pins 2, 5, 10, 13) | Input B of Gate n | Second input terminal per gate; Schmitt-trigger action improves noise immunity on slow or noisy lines. |
| 1Y, 2Y, 3Y, 4Y (Pins 3, 6, 8, 11) | Output Y of Gate n | Active-high OR output; drives loads up to ±8 mA while maintaining VOL ≤ 0.55 V and VOH ≥ 3.70 V. |
| GND (Pin 7) | Ground reference | 0 V return path for all internal circuitry and I/O; must be low-impedance for stable noise margin. |
| VCC (Pin 14) | Positive supply | Primary power rail (4.5–5.5 V); decoupling capacitor (100 nF) recommended within 10 mm of this pin. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use with full temperature range (−40 °C to +125 °C) and reliability testing per stress test conditions. |
| TTL-compatible input levels | VIH ≥ 2.0 V and VIL ≤ 0.8 V at 5 V supply - enables seamless integration with legacy 5 V microcontrollers and peripheral ICs. |
| Schmitt-trigger inputs | Hysteresis on all inputs rejects noise up to ~0.3 V, preventing false triggering on slow or noisy control lines. |
| Voltage-tolerant inputs | Accepts input voltages up to 7.0 V regardless of VCC - allows safe interfacing with higher-voltage sensors or open-drain buses. |
| SO14 package with side-wettable flanks | SOT108-1 footprint supports automated optical inspection (AOI) of solder joints, improving production yield in automotive PCB assembly. |

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 |
|---|---|---|---|
| 74VHC32D-Q100 | CMOS input thresholds (VIH = 3.85 V @ VCC = 5.5 V); wider VCC range (2.0–5.5 V) | Better suited for mixed-voltage systems with 3.3 V logic domains | Select when interfacing with CMOS microcontrollers or low-voltage peripherals. |
| SN74LVC32APWR | 3.3 V-only operation (1.65–3.6 V); lower propagation delay (4.8 ns typ); non-automotive grade | Limited to cabin infotainment or non-safety modules without AEC-Q100 requirement | Choose for cost-sensitive, non-under-hood applications requiring faster speed and smaller TSSOP footprint. |
Compared with 74VHC32D-Q100 and SN74LVC32APWR, the 74VHCT32D-Q100 uniquely balances TTL compatibility, AEC-Q100 Grade 1 qualification, and SO14 manufacturability-making it the only option qualified for under-hood OR logic where both legacy interface and automotive reliability are mandatory.

FAQ
Is 74VHCT32D-Q100 pin-compatible with standard 74LS32?
Yes - it is fully pin-compatible with Low-power Schottky TTL (LSTTL) devices including 74LS32. The SO14 footprint, pin numbering, and logic function match exactly, enabling direct replacement without PCB redesign. Input thresholds and output drive are optimized for TTL interoperability.
What is the maximum capacitive load this device can drive reliably?
The 74VHCT32D-Q100 is characterized up to 50 pF load capacitance with guaranteed tpd ≤ 9.0 ns and VOL ≤ 0.55 V at VCC = 4.5 V. Driving >50 pF may increase propagation delay nonlinearly and degrade noise margins; for heavier loads, add a buffer stage or reduce trace length and stubs.
Does this part support 3.3 V operation?
No - the 74VHCT32D-Q100 is specified only for VCC = 4.5 V to 5.5 V. Its TTL-compatible inputs require ≥2.0 V VIH, which cannot be met reliably below 4.5 V supply. For 3.3 V systems, use the 74VHC32D-Q100 variant or SN74LVC32A instead.
How does the Schmitt-trigger input improve system robustness?
Schmitt-trigger inputs provide hysteresis (~0.3 V typical), meaning the rising threshold (VIH) and falling threshold (VIL) differ. This prevents oscillation or chatter on slowly transitioning or noisy signals - such as those from mechanical switches or long harness runs - ensuring clean, single-event logic transitions.
