Nexperia USA Inc. 74AHC32BQ-Q100X

Overview

74AHC32BQ-Q100 from Nexperia is an automotive-qualified quad 2-input OR gate in DHVQFN14 package, operating from 2.0 V to 5.5 V supply, with CMOS-level inputs, -40 °C to +125 °C temperature range, and overvoltage-tolerant inputs up to 5.5 V. It serves as a logic-level translator in mixed-voltage automotive subsystems such as body control modules and sensor interface circuits.

For engineers reviewing the 74AHC32BQ-Q100 datasheet, 74AHC32BQ-Q100 pinout, 74AHC32BQ-Q100 application, or 74AHC32BQ-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, propagation delay ≤7.0 ns (VCC = 4.5–5.5 V, CL = 15 pF), input overvoltage tolerance, Schmitt-trigger inputs for noise immunity, and DHVQFN thermal performance with side-wettable flanks.

Technical Context

This device implements four independent OR logic functions (A + B → Y) with balanced tPLH/tPHL propagation delays and identical input/output thresholds across all channels. Its CMOS input structure ensures compatibility with 3.3 V and 5 V logic families while maintaining low static current (ICC ≤ 40 μA at VCC = 5.5 V).

The DHVQFN14 package (SOT762-1) features a thermally enhanced, leadless construction with 2.5 × 3 × 0.85 mm footprint and side-wettable flanks for AOI-capable solder joint inspection-critical for automotive PCB assembly traceability and reliability validation.

Compared with 74AHCT32BQ-Q100, the 74AHC32BQ-Q100 offers superior noise immunity and mixed-voltage flexibility due to its CMOS input threshold scaling with VCC, while SN74LVC32APWR trades qualification for broader low-voltage support and lower quiescent current-making it unsuitable for powertrain but viable for cabin electronics.

FAQ

Is the exposed thermal pad on the DHVQFN14 package electrically connected?

No-the exposed pad (Pin 1 index area) is not electrically tied to any internal node. Per datasheet note, it may remain floating or be connected to GND at the PCB layout level, but has no electrical requirement for soldering. If soldered, it must not be connected to any voltage other than GND.

Can 74AHC32BQ-Q100 interface directly with 5 V TTL outputs?

Yes-its inputs tolerate up to 5.5 V regardless of VCC level, and VIH minimum is 3.85 V at VCC = 5.5 V. When powered at 5.0 V, it fully accepts standard TTL HIGH levels (≥2.4 V), making it compatible with legacy 5 V TTL outputs without external level shifting.

What is the maximum output current per channel, and how is it distributed across all four gates?

Each output drives ±8.0 mA (sink/source) continuously. The total device supply current (ICC) remains ≤75 mA under worst-case switching conditions, and the 500 mW power dissipation limit applies to the entire package-not per gate-so simultaneous switching of all four outputs must stay within thermal limits at elevated ambient temperatures.

Does this part support partial power-down or I/O isolation when VCC = 0 V?

No-this is a standard CMOS logic gate without Ioff or power-down modes. When VCC = 0 V, inputs and outputs become high-impedance only if no external voltage is applied; however, applying input voltages >0.5 V above GND or < –0.5 V below GND while VCC = 0 V violates absolute maximum ratings and risks latch-up or damage.
