Product details
Overview
NL27WZ00USH from onsemi is a dual 2-input NAND gate IC operating from 1.65 V to 5.5 V, delivering 2.4 ns typical propagation delay at 5.0 V, 24 mA balanced output drive, and over-voltage tolerant inputs. It serves as a high-speed logic building block in level-shifting, signal conditioning, and control-path applications within portable and industrial digital systems.
For engineers reviewing the NL27WZ00USH datasheet, pinout, applications, or equivalent options, key selection criteria include supply voltage range (1.65–5.5 V), propagation delay (2.4 ns typ. @ 5 V), input overvoltage tolerance, LVTTL/LVCMOS interface compatibility, and US8 package thermal performance (θJA = 250 °C/W).
Technical Context
The NL27WZ00USH implements two independent NAND gates in a single US8 package, each with symmetrical input structure and rail-to-rail output swing. Its CMOS design supports mixed-voltage interfacing - e.g., 3.0 V VCC operation with 5.0 V TTL inputs - enabled by over-voltage tolerant inputs and LVTTL-compatible thresholds.
It features near-zero static ICC (≤10 µA) and dynamic power governed by CPD = 9–11 pF, making it suitable for low-power battery-operated logic. The device meets ESD ratings >2000 V (HBM) and latch-up immunity of ±500 mA per JEDEC JESD78, supporting robust operation in noisy industrial environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.65 V to 5.5 V - enables direct integration into 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains without level shifters. |
| Propagation Delay (tPD) | 2.4 ns typical at VCC = 5.0 V - supports >200 MHz toggle rates in critical timing paths. |
| Output Drive | ±24 mA - provides sufficient current to drive multiple LVTTL loads or small capacitive buses directly. |
| Input Voltage Tolerance | Up to 7.0 V - allows safe interfacing with legacy 5 V signals even when powered from 1.8 V or 2.5 V rails. |
| Quiescent Current (ICC) | ≤10 µA max - minimizes standby power in always-on subsystems such as wake-up logic or sensor interfaces. |
| Operating Temperature | −55 °C to +125 °C - qualified for extended industrial and automotive under-hood applications. |
Pinout & Package
The NL27WZ00USH is housed in an 8-pin US8 (SOIC-8 thin shrink) package (Case 493), measuring 2.0 × 2.2 mm footprint with 0.5 mm pitch, optimized for space-constrained PCB layouts and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 | First NAND gate input A - accepts logic levels across full 0–7 V range regardless of VCC. |
| 2 | B1 | First NAND gate input B - electrically identical to Pin 1; both inputs share same overvoltage tolerance. |
| 3 | Y2 | Second NAND gate output - active-low logic; sinks or sources up to 24 mA with rail-aligned VOH/VOL. |
| 4 | GND | Dedicated ground reference - must be connected to system ground plane to ensure noise immunity and stable DC bias. |
| 5 | A2 | Second NAND gate input A - independent of Gate 1; supports asynchronous logic combining or enable functions. |
| 6 | B2 | Second NAND gate input B - paired with Pin 5 to form second 2-input NAND function. |
| 7 | Y1 | First NAND gate output - complements inputs A1/B1; drives downstream logic or pull-up/pull-down networks. |
| 8 | VCC | Positive supply rail - powers both gates; decoupling capacitor (0.1 µF) required within 5 mm for AC stability. |
Key Features
| Feature | Design Value |
|---|---|
| High-speed switching | 2.4 ns tPD at 5 V enables use in clock distribution, address decoding, and fast control loops. |
| Mixed-voltage interface capability | LVTTL compatibility at 3.0 V VCC allows seamless connection to 5 V microcontrollers or FPGAs without external translators. |
| Balanced output drive | ±24 mA ensures consistent rise/fall times and reliable fanout to ≥10 LVTTL loads. |
| Ultra-low static power | ≤10 µA ICC eliminates need for power gating in always-active logic blocks like reset synchronizers. |
Applications
| Industrial Sensor Interface | Portable Device Power Control |
|---|---|
Use Scenario: Signal conditioning and enable logic for analog sensor outputs feeding an MCU ADC. IC Role / Device Role / Timing Role: Dual NAND gate performs active-low enable gating and debounce logic for interrupt lines.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 2-input NAND gate applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NC7WZ00M5X | Same logic function and speed, but in SC-70-5 package (5-pin); only one gate per package - requires two units for dual functionality. | Not pin-compatible; occupies more board area due to dual-package requirement and lacks GND/VCC separation per gate. | Select NC7WZ00M5X only if ultra-small single-gate density is prioritized over dual-gate integration and layout efficiency. |
| SN74LVC2G00DBVR | Identical dual NAND function, 2.5 ns tPD, but rated only to 125 °C (not −55 °C); no overvoltage-tolerant inputs (VI max = VCC + 0.5 V). | Unsuitable for mixed-voltage or extended temperature environments; requires external clamping for 5 V input interfacing. | Choose SN74LVC2G00DBVR only for commercial-grade 3.3 V-only systems where cost is primary and environmental ruggedness is secondary. |
Compared with NC7WZ00M5X and SN74LVC2G00DBVR, the NL27WZ00USH uniquely combines dual-gate integration in a thermally efficient US8 package, −55 °C to +125 °C operation, and true overvoltage-tolerant inputs - enabling single-component solutions in mixed-voltage industrial and automotive control logic.

FAQ
What is the maximum input voltage the NL27WZ00USH can tolerate?
The NL27WZ00USH supports DC input voltages up to 7.0 V regardless of VCC level, as confirmed in its Maximum Ratings table. This overvoltage tolerance allows safe interfacing with 5 V signals even when the device is powered from 1.65 V or 1.8 V rails - a key differentiator versus standard LVCMOS gates. The NL27WZ00USH achieves this via internal input protection circuitry validated per JEDEC standards.
Does the NL27WZ00USH support operation at 1.65 V supply?
Yes, the NL27WZ00USH is fully specified for operation down to 1.65 V VCC, with guaranteed AC and DC parameters including tPD ≤ 10.5 ns (max) and VIH ≥ 0.75 × VCC. This makes the NL27WZ00USH suitable for ultra-low-voltage applications such as energy-harvesting sensors and battery-powered wearables where supply rails dip below 1.8 V.
Is the NL27WZ00USH pin-compatible with the NC7WZ00?
Yes, the NL27WZ00USH is a direct replacement for the NC7WZ00 in the US8 package, sharing identical pinout, electrical specifications, and functional behavior. The datasheet explicitly states "Replacement for NC7WZ00", and both devices use Pin 1=A1, Pin 2=B1, Pin 3=Y2, Pin 4=GND, Pin 5=A2, Pin 6=B2, Pin 7=Y1, Pin 8=VCC - verified in Figures 1 and 2 of the NL27WZ00/D datasheet.
What is the thermal resistance (θJA) of the NL27WZ00USH in its US8 package?
The NL27WZ00USH has a junction-to-ambient thermal resistance (θJA) of 250 °C/W, measured on an FR4 board with minimum pad spacing and no airflow. This value is specified in the Maximum Ratings table and reflects realistic thermal performance in compact, unventilated PCB layouts - critical for predicting junction temperature rise under sustained 24 mA output loading.
Does the NL27WZ00USH require external pull-up resistors on its outputs?
No, the NL27WZ00USH does not require external pull-up resistors because it features actively driven outputs capable of sourcing up to 24 mA. Its CMOS push-pull structure delivers rail-to-rail VOH and VOL across all load conditions, eliminating the need for passive pull-ups used in open-drain or TTL-compatible logic families. This simplifies BOM and improves rise/fall time consistency in the NL27WZ00USH design.
