Product details
Overview
NLV74HC32ADR2G from onsemi is a quad 2-input OR gate logic IC in SOIC-14 package, operating across 2.0–6.0 V supply, delivering 10 LSTTL load drive capability with propagation delay as low as 13 ns at 6.0 V, used for digital signal combining in industrial control and sensor interface circuits.
For engineers reviewing the NLV74HC32ADR2G datasheet, pinout, applications, or equivalent options, key selection considerations include supply voltage range compatibility (2.0–6.0 V), guaranteed propagation delay at temperature extremes (≤110 ns at −55°C to +125°C), input/output voltage thresholds, and SOIC-14 footprint constraints.
Technical Context
The NLV74HC32ADR2G implements four independent CMOS-based OR gates (Y = A + B) using high-performance silicon-gate technology. Each gate features symmetrical input structure, rail-to-rail output swing, and TTL/CMOS-compatible inputs when pulled up.
It operates over an extended industrial temperature range (−55°C to +125°C) and meets JEDEC Std. No. 7A requirements. Input leakage current is limited to ±1.0 µA at 6.0 V, and quiescent supply current remains ≤40 µA across temperature.
Key Specifications

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 |
|---|---|---|---|
| MC74HC32ADR2G | Same logic function, identical pinout, but rated for −40°C to +85°C only; no automotive qualification. | Not qualified for AEC-Q100; unsuitable for under-hood or extended-temperature industrial use. | Select NLV74HC32ADR2G when operation beyond +85°C or automotive PPAP compliance is required. |
| SN74HC32DR | TI part with same logic and SOIC-14 package; VIH/VIL thresholds differ slightly (VIH = 3.15 V min at 4.5 V). | Requires validation of input threshold compatibility in mixed-vendor 3.3 V systems. | Prefer NLV74HC32ADR2G where guaranteed −55°C start-up or onsemi's extended temp qualification is mandatory. |
Compared with MC74HC32ADR2G and SN74HC32DR, the NLV74HC32ADR2G uniquely guarantees full functionality down to −55°C and includes AEC-Q100 qualification-critical for automotive body electronics and industrial controllers exposed to extreme thermal transients.

FAQ
What is the maximum operating temperature range for NLV74HC32ADR2G?
The NLV74HC32ADR2G is specified for continuous operation from −55°C to +125°C. This extended range is validated per JEDEC standards and supports deployment in under-hood automotive locations, industrial motor drives, and outdoor energy infrastructure where ambient temperatures exceed standard commercial limits. The NLV74HC32ADR2G maintains full logic functionality and timing compliance across this entire span without derating.
Is NLV74HC32ADR2G pin-compatible with standard 74HC32 devices?
Yes, the NLV74HC32ADR2G uses the industry-standard SOIC-14 pinout identical to LS32 and all 74HC32 variants, including MC74HC32ADR2G and SN74HC32DR. Pin 1 is index marker, pins 1–2–4–5–9–10–12–13 are inputs, pins 3–6–8–11 are outputs, pin 7 is GND, and pin 14 is VCC. No PCB layout change is needed when upgrading from commercial-grade HC32 to NLV74HC32ADR2G.
Does NLV74HC32ADR2G support 3.3 V logic systems?
Yes, the NLV74HC32ADR2G operates reliably at 3.3 V supply (within its 2.0–6.0 V range). At VCC = 3.3 V, VIH is guaranteed ≥2.10 V and VIL ≤0.90 V, providing >1.2 V noise margin. Its output VOH ≥2.48 V and VOL ≤0.26 V at 3.3 V ensure clean interfacing with 3.3 V microcontrollers and FPGAs without level shifters.
What automotive qualifications does NLV74HC32ADR2G hold?
The NLV74HC32ADR2G is AEC-Q100 qualified (Grade 1: −40°C to +125°C ambient, plus extended testing to −55°C) and PPAP capable. It meets stress test requirements for HTOL, TCT, HAST, and ESD (HBM >2000 V), and carries the "−Q" suffix designation in onsemi's ordering matrix-confirming automotive-grade process controls and traceability.
How does NLV74HC32ADR2G differ from MC74HC32ADR2G?
The NLV74HC32ADR2G differs from MC74HC32ADR2G primarily in temperature rating and qualification: NLV is rated −55°C to +125°C and AEC-Q100 qualified; MC74HC32ADR2G is rated −40°C to +85°C and intended for commercial/industrial use only. Both share identical electrical specs, pinout, and SOIC-14 packaging-but only NLV74HC32ADR2G supports automotive PPAP and extreme cold-start operation.
