Product details
Overview
NC7WZ32L8X from Fairchild Semiconductor is a dual 2-input OR gate in the TinyLogic® UHS family, fabricated using advanced CMOS for ultra-high-speed logic operation with ±24 mA output drive at 3V and operation across 1.65V–5.5V supply range. It features overvoltage-tolerant inputs (up to 7V), power-down high-impedance I/O, and is used in level translation and portable logic interfacing.
For engineers reviewing the NC7WZ32L8X datasheet, pinout, applications, or equivalent options, key selection criteria include propagation delay (2.4 ns typ @ 5V/50 pF), input overvoltage tolerance, MicroPak® package footprint, and 1.65V minimum VCC compatibility for low-voltage battery-powered systems.
Technical Context
The NC7WZ32L8X implements two independent OR gates (Y₁ = A₁ + B₁, Y₂ = A₂ + B₂) with rail-to-rail CMOS output swing and input thresholds scaled to VCC (VIH = 0.7VCC, VIL = 0.3VCC at VCC ≥ 2.3V). Its inputs remain high-impedance and tolerant up to 7V regardless of VCC, enabling robust 5V-to-3V signal translation without external components.
It operates with ultra-low static current (ICC ≤ 10 µA) and supports dynamic loading up to 50 pF. Propagation delay varies with VCC and load: 0.5 ns (min) / 3.3 ns (max) @ 5V/50 pF, and 1.2 ns (min) / 5.2 ns (max) @ 3.3V/50 pF - confirming true UHS performance across its full voltage range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65V to 5.5V - enables single-supply operation across 1.8V, 2.5V, 3.3V, and 5V logic domains |
| tPD (Typ) | 2.4 ns @ 5V into 50 pF - meets timing budgets for high-speed control logic in portable and interface circuits |
| IOH/IOL | ±24 mA @ 3V - drives multiple 74LVC inputs or small capacitive loads without buffering |
| Input Voltage Tolerance | −0.5V to +7V - allows safe interfacing with higher-voltage signals (e.g., 5V microcontroller outputs to 3.3V FPGA inputs) |
| Power-Down Behavior | High-impedance I/O when VCC = 0V - prevents back-driving and leakage during power sequencing or sleep modes |
| Operating Temperature | −40°C to +85°C - qualified for industrial ambient environments without derating |
Pinout & Package
Pb-free 8-lead MicroPak® package (Package Code MAC08A), 1.6 mm wide, leadless, bottom-terminal land grid array with exposed thermal pad. No external leads - soldered directly via bottom pads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Input 1 of OR Gate 1 | Active-HIGH logic input; accepts 0–7V regardless of VCC |
| 2 (B1) | Input 2 of OR Gate 1 | Second active-HIGH input for first OR function |
| 3 (GND) | Ground Reference | Return path for all I/O and internal circuitry; must be low-inductance connection |
| 4 (Y1) | Output of OR Gate 1 | CMOS push-pull output; rail-to-rail swing (0V to VCC) |
| 5 (Y2) | Output of OR Gate 2 | Independent CMOS output; electrically isolated from Y1 |
| 6 (B2) | Input 2 of OR Gate 2 | Second input for second OR gate; identical electrical behavior to A1/B1 |
| 7 (A2) | Input 1 of OR Gate 2 | First input for second OR gate; fully overvoltage tolerant |
| 8 (VCC) | Positive Supply | Single supply rail; powers both gates; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-High-Speed Propagation | 2.4 ns typical tPD @ 5V/50 pF - enables sub-10 ns combinatorial paths in compact logic designs |
| Overvoltage-Tolerant Inputs | 7V absolute max input rating - eliminates need for external clamping diodes in mixed-voltage systems |
| Wide Supply Range | 1.65V–5.5V operation - supports direct integration into battery-powered, multi-rail, and legacy 5V systems |
| MicroPak® Package | 1.6 mm × 1.6 mm footprint, 0.5 mm pitch - saves >70% board area vs. SOIC-8 while maintaining thermal reliability |
| Power-Down High-Z I/O | Inputs and outputs float to high impedance when VCC = 0V - prevents contention during hot-swap or partial-power-down sequences |
Applications

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 |
|---|---|---|---|
| SN74LVC2G32DCUR | SO-8 package (3.0 × 3.0 mm); slightly slower tPD (3.5 ns typ @ 3.3V); same VCC range and drive strength | Requires larger PCB area; less suitable for ultra-dense portable layouts | Select when SO-8 reworkability or legacy footprint compatibility is prioritized over size |
| 74AUP2G32GM,115 | Smaller XSON-8 (1.35 × 1.35 mm); lower ICC (0.9 µA typ); slower tPD (6.3 ns typ @ 3.3V) | Better for ultra-low-power always-on monitoring; not suitable for <10 ns timing-critical paths | Select when nanowatt standby current outweighs speed requirements |
Compared with SN74LVC2G32DCUR and 74AUP2G32GM,115, the NC7WZ32L8X delivers the best balance of speed (2.4 ns), size (1.6 mm²), and overvoltage tolerance (7V) - making it optimal for space-constrained, mixed-voltage, high-timing-margin designs.

FAQ
What is the maximum input voltage the NC7WZ32L8X can tolerate?
The NC7WZ32L8X supports DC input voltages from −0.5V to +7V, independent of VCC. This overvoltage tolerance allows safe interfacing with 5V signals even when operating at 1.8V or 2.5V supply, eliminating external protection components. The specification is verified per Absolute Maximum Ratings in the official Fairchild datasheet DS500270.
Does the NC7WZ32L8X have power-down functionality?
Yes - when VCC = 0V, both inputs and outputs of the NC7WZ32L8X enter a high-impedance state. This prevents back-driving, reduces leakage, and supports clean power sequencing in multi-rail systems. The behavior is intrinsic to the device's design and does not require external control signals.
What is the typical propagation delay of the NC7WZ32L8X at 3.3V supply?
At VCC = 3.3V ± 0.3V and CL = 50 pF, the NC7WZ32L8X exhibits a typical propagation delay (tPLH/tPHL) of 2.6 ns, with a maximum of 4.3 ns over temperature. This value is measured under standard AC test conditions defined in Figure 1 and Figure 3 of the NC7WZ32L8X datasheet DS500270.
Is the NC7WZ32L8X pin-compatible with other TinyLogic® UHS dual OR gates?
No - the NC7WZ32L8X uses the MicroPak® (MAC08A) package with bottom terminals, while other variants like NC7WZ32K8X use US8 (MAB08A) with gull-wing leads. Pin numbering and physical layout differ; PCB redesign is required when switching between L8X and K8X variants.
What is the thermal resistance (θJA) of the NC7WZ32L8X in its MicroPak® package?
The NC7WZ32L8X has a junction-to-ambient thermal resistance (θJA) of 250°C/W, measured under standard JEDEC JESD51-2 conditions with no copper pour. Effective thermal performance improves significantly with PCB copper thermal vias under the exposed pad - a design practice recommended in Fairchild's MicroPak® mounting guidelines.
