Product details
Overview
74VHC32BQ-Q100 from Nexperia is a quad 2-input OR gate in DHVQFN14 package, qualified to AEC-Q100 Grade 1 for automotive use. It operates from -40 °C to +125 °C with CMOS input levels, 5.5 V max supply, and propagation delay as low as 2.8 ns (VCC = 4.5–5.5 V, CL = 15 pF). It serves as a logic-level combiner in body control modules and powertrain signal conditioning.
For engineers reviewing the 74VHC32BQ-Q100 datasheet, 74VHC32BQ-Q100 pinout, 74VHC32BQ-Q100 application, or 74VHC32BQ-Q100 equivalent, key selection criteria include automotive temperature range compliance, DHVQFN thermal performance, Schmitt-trigger input tolerance, and TTL/CMOS input level compatibility across variants.
Technical Context
This device implements four independent 2-input OR logic functions using high-speed Si-gate CMOS technology, pin-compatible with LSTTL. Its inputs accept voltages up to 7.0 V regardless of VCC, and all inputs feature Schmitt-trigger action for noise immunity on slow-rising signals.
It supports dual-voltage system interfacing: the 74VHC32BQ-Q100 variant uses CMOS input thresholds (VIH ≥ 3.85 V at VCC = 5.5 V), while its 74VHCT32BQ-Q100 counterpart accepts standard TTL input levels (VIH ≥ 2.0 V). Both share identical pinout, package, and output drive capability (±8 mA).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Four independent 2-input OR gates; outputs true when either input is HIGH. |
| Supply Voltage Range | 2.0 V to 5.5 V - enables operation across 3.3 V and 5 V automotive subsystems. |
| Propagation Delay | 2.8 ns typical (VCC = 4.5–5.5 V, CL = 15 pF) - supports >100 MHz toggle rates in critical timing paths. |
| Input Voltage Tolerance | −0.5 V to +7.0 V - allows safe interfacing with higher-voltage sensors or legacy 5 V logic without level shifters. |
| Output Drive | ±8 mA at VCC = 4.5 V - sufficient to drive multiple CMOS loads or short PCB traces in distributed control units. |
| ESD Protection | HBM >2000 V, CDM >1000 V - meets automotive robustness requirements for assembly and field operation. |
| Operating Temperature | −40 °C to +125 °C - qualified per AEC-Q100 Grade 1 for under-hood and transmission control applications. |
Pinout & Package
DHVQFN14 (SOT762-1) package: 2.5 × 3.0 × 0.85 mm body, side-wettable flanks for AOI-compatible solder joint inspection, thermally enhanced for automotive ambient conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 2A, 3A, 4A | Data input A for gates 1–4 | Accepts CMOS-level signals; Schmitt-triggered for noise rejection on slow edges. |
| 1B, 2B, 3B, 4B | Data input B for gates 1–4 | Electrically identical to A inputs; enables full 2-input OR functionality per gate. |
| 1Y, 2Y, 3Y, 4Y | Data output Y for gates 1–4 | Push-pull CMOS output; drives HIGH to VCC or LOW to GND with rail-to-rail swing. |
| 7 | GND | Primary ground reference; must be connected to system 0 V plane for stable logic thresholds. |
| 14 | VCC | Positive supply input; decoupling capacitor (100 nF) required within 5 mm for noise suppression. |
| Exposed pad | Thermal pad (non-electrical) | No electrical requirement; may be left floating or tied to GND for improved thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for automotive use from −40 °C to +125 °C ambient, including lifetime reliability testing. |
| Side-wettable flanks (SWF) | Enables automated optical inspection (AOI) of solder joints on bottom-terminated QFN packages. |
| Input overvoltage tolerance | Inputs withstand −0.5 V to +7.0 V independent of VCC - eliminates need for external clamping in mixed-voltage systems. |
| Schmitt-trigger inputs | Hysteresis of ~0.3 V (typ.) improves noise margin on noisy automotive harnesses or long PCB traces. |
| Low dynamic power | CPD = 10 pF - limits switching power to <1 μW per gate at 1 MHz, reducing thermal load in dense ECUs. |
Applications
| Body Control Module (BCM) | Powertrain Control Unit (PCU) |

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 |
|---|---|---|---|
| 74VHCT32BQ-Q100 | TTL-compatible inputs (VIH ≥ 2.0 V); otherwise identical pinout, package, and speed. | Required when interfacing with legacy 5 V TTL logic or microcontrollers lacking 3.3 V-tolerant I/O. | Select when driving from 5 V microcontrollers or industrial PLC outputs without level translation. |
| SN74LVC32APWR | Lower VCC range (1.65–5.5 V), non-automotive grade, SOIC/TSSOP only, no AEC-Q100 qualification. | Restricted to commercial/industrial environments; unsuitable for under-hood deployment. | Use only in non-automotive designs where cost or availability outweighs qualification requirements. |
Compared with 74VHC32BQ-Q100, the 74VHCT32BQ-Q100 offers direct TTL interface compatibility at identical thermal and mechanical specs, while SN74LVC32APWR trades automotive qualification for broader voltage flexibility and lower unit cost in non-automotive contexts.

FAQ
Can 74VHC32BQ-Q100 operate at 3.3 V supply?
Yes. The 74VHC32BQ-Q100 is fully specified down to 2.0 V supply, with guaranteed VIH ≥ 2.1 V and VOL ≤ 0.36 V at VCC = 3.0 V and IO = 4.0 mA. Propagation delay is 3.9 ns (typ.) at 3.0 V/15 pF, making it suitable for 3.3 V automotive domains such as infotainment and gateway modules.
Is the exposed thermal pad electrically connected?
No. The exposed pad in the SOT762-1 (DHVQFN14) package is not electrically connected to any internal node. Per Nexperia's datasheet, it has no electrical or mechanical requirement to be soldered; if connected, it must remain floating or be tied to GND to avoid unintended coupling or thermal stress.
What is the maximum input transition rate supported?
At VCC = 4.5–5.5 V, the device supports input rise/fall rates as slow as 20 ns/V - meaning a 5 V transition can take up to 100 ns without causing metastability. This accommodates mechanically switched inputs or long cable runs common in vehicle wiring harnesses.
Does this part support hot insertion?
No. The 74VHC32BQ-Q100 lacks hot-swap protection circuitry. Absolute maximum ratings specify VI and VCC limits but do not guarantee safe operation during live insertion. System-level protection (e.g., series resistors, TVS diodes) is required if hot-plug capability is needed in modular automotive subsystems.
