Product details
Overview
NL27WZ32USG-Q from onsemi is a dual 2-input OR gate logic IC designed for high-speed, low-voltage operation across automotive and industrial systems. It operates from 1.65 V to 5.5 V, delivers 2.5 ns typical propagation delay at 5 V, supports ±24 mA I/O drive at 3.0 V, and features overvoltage-tolerant inputs/outputs up to 5.5 V - enabling robust interfacing in mixed-supply environments such as CAN/LIN bus interface level-shifting and microcontroller GPIO expansion.
For engineers reviewing the NL27WZ32USG-Q datasheet, pinout, applications, or equivalent options, key selection criteria include its AEC-Q100 qualification, IOFF partial power-down protection, US8 package footprint compatibility, and guaranteed performance across −55 °C to +125 °C operating temperature range.
Technical Context
The NL27WZ32USG-Q implements two independent CMOS OR gates with rail-to-rail input voltage tolerance and active-drive output stages. Its logic function follows Y = A + B per gate, with defined HIGH/LOW thresholds scaling with VCC (e.g., VIH = 0.70 × VCC for VCC ≥ 2.3 V).
It incorporates IOFF circuitry that disables I/O paths when VCC = 0 V, preventing back-powering and signal contention during partial power-down states - critical for hot-swap and multi-rail system designs where supply sequencing is non-deterministic.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables direct interface with 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| tPD (Typ) | 2.5 ns at VCC = 5 V - supports >300 MHz toggle rates in high-speed control paths like clock enable gating. |
| I/O Drive | ±24 mA at 3.0 V - sufficient to directly drive LEDs, small MOSFET gates, or multiple 74LVC inputs without buffers. |
| Input Tolerance | Up to 5.5 V regardless of VCC - allows safe connection to higher-voltage signals (e.g., 5 V sensors) while powered from 1.8 V. |
| IOFF Protection | Active when VCC = 0 V - blocks current flow between powered and unpowered sections, meeting automotive ASAM-19 requirements. |
| Operating Temp | −55 °C to +125 °C - qualified for under-hood automotive ECUs and industrial motor control enclosures. |
| ESD Rating | HBM 2000 V, CDM 1000 V - exceeds AEC-Q100 stress test levels for production reliability. |
Pinout & Package
Package: US8 (8-pin Ultra Small Outline Package), Case 493, 2.1 mm × 2.0 mm footprint, 0.5 mm pitch, Pb-free, RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 | First OR gate input - accepts 0–5.5 V logic signals independent of VCC level. |
| 2 | B1 | First OR gate second input - dual-input OR logic path with A1 feeds Y2 (Pin 3). |
| 3 | Y2 | Output of first OR gate - drives loads up to ±24 mA at 3.0 V with 2.5 ns tPD. |
| 4 | GND | Digital ground reference - must be connected to system ground plane for noise immunity and ESD return path. |
| 5 | A2 | Second OR gate input - electrically isolated from A1/B1; shares no internal nodes with first gate. |
| 6 | B2 | Second OR gate second input - enables independent dual-gate operation in compact space-constrained layouts. |
| 7 | Y1 | Output of second OR gate - pin-compatible with Y2 but physically separated for routing flexibility. |
| 8 | VCC | Positive supply - powers both gates; IOFF activates automatically if disconnected or pulled to 0 V. |
Key Features
| Feature | Design Value |
|---|---|
| Wide VCC Range | 1.65–5.5 V operation eliminates need for separate voltage translators in multi-rail MCU subsystems. |
| Overvoltage-Tolerant I/O | Inputs and outputs withstand 5.5 V even at 1.65 V VCC - enables safe interfacing with legacy 5 V peripherals. |
| IOFF Partial Power-Down | Prevents back-current leakage when VCC is off - essential for modular systems with hot-pluggable modules. |
| AEC-Q100 Qualified | Qualified to Grade 1 (−40 °C to +125 °C) with PPAP capability - meets OEM automotive qualification requirements. |
| Low Input Capacitance | 2.5 pF typical - minimizes loading on high-impedance sources like crystal oscillator outputs or sensor amplifiers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input OR gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MC74VHC1G32DTT1G | Same US8 package, 2 ns tPD at 5 V, but only rated to 3.6 V VCC max and lacks IOFF. | Not AEC-Q100 qualified; unsuitable for automotive hot-swap or multi-rail partial power-down use cases. | Select only for cost-sensitive consumer applications requiring faster speed below 3.6 V. |
| SN74LVC2G32DBVR | US8 package, 3.3 V max VCC, 3.7 ns tPD at 3.3 V, IOFF supported, but not AEC-Q100 qualified. | Limited to industrial/commercial temp range (−40 °C to +85 °C); no PPAP documentation support. | Preferred for non-automotive embedded systems needing LVC-family compatibility and lower static current. |
Compared with MC74VHC1G32DTT1G and SN74LVC2G32DBVR, the NL27WZ32USG-Q uniquely combines automotive qualification, 5.5 V tolerance, and IOFF in a single US8 device - making it the only choice for AEC-Q100-compliant designs requiring interoperability across 1.8 V–5 V domains with robust power sequencing.

FAQ
What is the maximum input voltage rating for NL27WZ32USG-Q when VCC = 1.8 V?
The NL27WZ32USG-Q supports input voltages up to 5.5 V regardless of VCC level - meaning it safely accepts 5 V signals even when powered from 1.8 V. This overvoltage tolerance is explicitly specified in the Absolute Maximum Ratings table (VIN = −0.5 V to +6.5 V) and confirmed in the Recommended Operating Conditions (VIN = 0 to 5.5 V). The NL27WZ32USG-Q achieves this via internal clamping structures that prevent damage or false logic states during mixed-voltage interfacing.
Does NL27WZ32USG-Q support true tri-state operation?
No, the NL27WZ32USG-Q does not provide tri-state outputs. It is a standard dual 2-input OR gate with push-pull outputs only. The datasheet mentions "Tri-State Mode" only in the context of VOUT ratings under specific failure conditions (e.g., VOUT < GND), not as a functional mode. Output states are strictly HIGH or LOW based on the OR logic function; there is no enable/disable control pin or internal high-impedance state. For tri-state applications, designers must select a different logic family such as 74LVC or 74AUP with explicit OE pins.
Is NL27WZ32USG-Q pin-compatible with NL27WZ04USG-Q?
No, NL27WZ32USG-Q is not pin-compatible with NL27WZ04USG-Q. The NL27WZ32USG-Q is a dual 2-input OR gate (US8 pinout: A1, B1, Y2, GND, A2, B2, Y1, VCC), whereas NL27WZ04USG-Q is a hex inverter (US8 pinout: A1, Y1, A2, Y2, GND, A3, Y3, VCC). Their pin assignments differ fundamentally - for example, Pin 3 is Y2 in NL27WZ32USG-Q but Y1 in NL27WZ04USG-Q, and Pin 5 is A2 in NL27WZ32USG-Q but A2 in NL27WZ04USG-Q but with different adjacent functions. Substitution requires PCB redesign.
What is the significance of the "-Q" suffix in NL27WZ32USG-Q?
The "-Q" suffix in NL27WZ32USG-Q denotes an automotive-grade variant meeting AEC-Q100 qualification requirements and supporting PPAP (Production Part Approval Process) documentation. It indicates unique site and control change requirements - including enhanced traceability, extended temperature validation (−55 °C to +125 °C), and process controls aligned with automotive quality standards. This suffix distinguishes it from the commercial-grade NL27WZ32USG, which lacks formal automotive qualification and PPAP support, though both share identical electrical specifications and US8 packaging.
Can NL27WZ32USG-Q be used in a 1.2 V system?
No, NL27WZ32USG-Q cannot be operated in a 1.2 V system. Its minimum recommended VCC is 1.65 V per the Recommended Operating Conditions table. At 1.2 V, the device will not meet logic threshold specifications (VIH/VIL), propagation delay guarantees, or output drive strength - resulting in undefined behavior, increased static current, or complete functional failure. For 1.2 V logic, designers should consider newer families such as onsemi's NC7SV series or TI's AUP logic, which specify operation down to 0.8 V or 1.0 V.
