Product details
Overview
74HCT32BQ-Q100 from Nexperia is an automotive-qualified quad 2-input OR gate in DHVQFN14 package, operating from -40 °C to +125 °C with TTL-compatible inputs (VIH = 2.0 V min), 4.5–5.5 V supply range, and propagation delay of 11–36 ns at VCC = 4.5 V. It serves as a logic-level combiner in vehicle body control modules for door lock status aggregation.
For engineers reviewing the 74HCT32BQ-Q100 datasheet, 74HCT32BQ-Q100 pinout, 74HCT32BQ-Q100 application, or 74HCT32BQ-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, input level compatibility with legacy 5 V TTL systems, thermal performance in DHVQFN14, and symmetrical output drive capability (±4.0 mA).
Technical Context
This device implements four independent OR logic functions using CMOS technology with TTL-level input thresholds, enabling direct interfacing with standard 5 V microcontroller GPIOs without level translation. Each gate features clamp diodes on inputs, allowing safe operation with input voltages exceeding VCC when current-limited.
It delivers balanced high/low output impedance and matched propagation delays across all channels, supporting deterministic timing in safety-critical signal conditioning paths. The DHVQFN14 package provides enhanced thermal dissipation and AOI-compatible side-wettable flanks for automotive PCB assembly verification.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Logic Function | Quad 2-input OR gate - four independent Boolean OR operations per package |
| Supply Voltage Range | 4.5 V to 5.5 V - matches standard automotive 5 V rail with ±10% tolerance |
| Input Threshold (VIH/VIL) | VIH ≥ 2.0 V, VIL ≤ 0.8 V - TTL-compatible input levels ensure interoperability with legacy 5 V logic families |
| Propagation Delay (tpd) | 11–36 ns at VCC = 4.5 V, CL = 50 pF - enables reliable operation in sub-30 MHz combinatorial logic paths |
| Output Drive (IO) | ±4.0 mA at VOH/VOL - sufficient to drive multiple 74-series inputs or small LED indicators directly |
| Operating Temperature | -40 °C to +125 °C - qualified for under-hood and cabin control unit environments |
| AEC-Q100 Grade | Grade 1 - certified for automotive applications requiring extended temperature reliability |
Pinout & Package
DHVQFN14 (SOT762-1) package: 2.5 × 3.0 × 0.85 mm body, no leads, 14 terminals, side-wettable flanks for automated optical inspection. Exposed thermal pad (Pin 1 index area) is electrically isolated; may be left floating or connected to GND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1A, 4A, 9A, 12A | Data Input A | First input of Gates 1–4; accepts TTL-level signals up to VCC + 0.5 V with clamping diode protection |

Use Value: Prevents spurious camera activation during vehicle startup transients; meets ISO 26262 hardware fault tolerance requirements. |
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 |
|---|---|---|---|
| 74HCT32D-Q100 | SO14 package (3.9 mm width); higher thermal resistance (10.1 mW/K derating above 100 °C) | Better suited for prototyping or legacy through-hole compatible designs; lacks AOI support | Select when board space allows larger footprint and manual inspection is acceptable |
| 74HCT32PW-Q100 | TSSOP14 package (4.4 mm width); moderate thermal resistance (7.3 mW/K derating above 81 °C) | Intermediate density option with improved thermal performance vs SO14 but less than DHVQFN | Choose for cost-sensitive automotive modules where DHVQFN reflow process is unavailable |
Compared with 74HCT32D-Q100 and 74HCT32PW-Q100, the 74HCT32BQ-Q100 offers superior thermal dissipation (9.6 mW/K derating above 98 °C), smallest footprint (2.5 × 3.0 mm), and AOI-enabled side-wettable flanks - making it the optimal choice for high-reliability, space-constrained automotive ECUs.

FAQ
What is the maximum input voltage allowed on 74HCT32BQ-Q100 pins?
The absolute maximum input voltage is VCC + 0.5 V per IEC 60134 limiting values. Inputs include clamp diodes, so voltages exceeding VCC are permissible only when current-limited to ±20 mA - for example, using a 1 kΩ resistor for a 12 V signal on a 5 V-powered device.
Can 74HCT32BQ-Q100 operate at 3.3 V supply?
No - the 74HCT32BQ-Q100 is specified only for 4.5–5.5 V operation per Table 5. At 3.3 V, VIH (2.0 V min) would exceed 60% of VCC, violating TTL input compatibility and risking unreliable logic detection; use 74HC32BQ-Q100 instead for 2.0–6.0 V wide-range operation.
Is the exposed thermal pad on the DHVQFN14 package electrically connected?
No - the exposed pad (terminal 1 index area) has no internal electrical connection. Per datasheet note, it may be left floating or connected to GND, but must not be tied to VCC or any other voltage. Soldering it to GND improves thermal performance without affecting logic functionality.
How does propagation delay vary with load capacitance?
Propagation delay increases linearly with load capacitance: tpd = 11 ns (CL = 15 pF) to 36 ns (CL = 50 pF) at VCC = 4.5 V. This 25 ns swing reflects gate drive strength limitations; for timing-critical paths, keep CL ≤ 20 pF or add series termination to reduce ringing-induced delay uncertainty.
