Product details
Overview
74AHCT32BQ-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, VIL = 0.8 V max at VCC = 4.5–5.5 V), 7.0 ns typical propagation delay (CL = 15 pF), and overvoltage-tolerant inputs up to 5.5 V - used for logic-level translation and signal combining in engine control units.
For engineers reviewing the 74AHCT32BQ-Q100 datasheet, 74AHCT32BQ-Q100 pinout, 74AHCT32BQ-Q100 application, or 74AHCT32BQ-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, DHVQFN thermal performance, TTL input compatibility, balanced propagation delays, and Schmitt-trigger input noise immunity.
Technical Context
This device implements four independent 2-input OR logic functions with true TTL input thresholds, enabling direct interfacing with legacy 5 V TTL outputs while powered from 4.5–5.5 V supplies. All inputs feature Schmitt-trigger action for enhanced noise rejection on slow-rising signals.
It supports mixed-voltage system design via overvoltage-tolerant inputs (up to 5.5 V regardless of VCC), allowing use as a level translator between 3.3 V logic domains and 5 V peripherals without external components. The DHVQFN14 package provides side-wettable flanks for AOI-capable solder joint inspection.

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 |
|---|---|---|---|
| 74AHC32BQ-Q100 | CMOS input thresholds (VIH = 3.85 V @ VCC = 5.5 V), wider 2.0–5.5 V supply range | Requires CMOS-level input drivers; unsuitable for direct TTL interface | Select when interfacing with 3.3 V or mixed-supply CMOS systems |
| SN74LVC32APWR | 3.3 V-only supply (1.65–3.6 V), LVCMOS thresholds, lower drive strength (24 mA) | Not AEC-Q100 qualified; limited to non-automotive industrial or consumer use | Select for cost-sensitive 3.3 V embedded designs outside automotive qualification scope |

FAQ
What is the maximum input voltage the 74AHCT32BQ-Q100 can tolerate?
The 74AHCT32BQ-Q100 supports overvoltage-tolerant inputs up to 5.5 V regardless of VCC level, enabling safe operation in mixed-voltage environments where input signals may exceed the supply rail - confirmed in Section 7 (Limiting Values) and Section 2 (Features) of the datasheet.
Does this device require external pull-up or pull-down resistors on unused inputs?
No. Unused inputs must be tied to VCC or GND to prevent floating states and excessive current draw; the datasheet explicitly prohibits leaving inputs unconnected due to CMOS input structure and potential shoot-through current - see Section 8 (Recommended Operating Conditions) and functional description.
Can the 74AHCT32BQ-Q100 operate reliably at 125 °C ambient temperature?
Yes. It is fully specified and qualified from -40 °C to +125 °C ambient, with static and dynamic parameters guaranteed across that full range per Table 5 (Operating Conditions) and Table 6/7 (Characteristics), and validated under AEC-Q100 Grade 1 thermal stress testing.
Is the exposed thermal pad on the DHVQFN package electrically connected?
No. The exposed pad (Pin 1 index area) is not electrically connected to any internal node; the datasheet states it has "no electrical or mechanical requirement to solder" - if soldered, it must remain floating or be connected to GND, as detailed in Section 5.1 Pinning information.
