Product details
Overview
NC7WZ38K8X-L22236 from onsemi is a dual 2-input NAND gate with open-drain outputs, fabricated in Ultra High Speed (UHS) CMOS technology. It operates across 1.65 V to 5.5 V VCC, delivers 2.2 ns typical propagation delay at 5 V, sinks up to 24 mA at 3 V, and features overvoltage-tolerant inputs (up to 5.5 V) for level translation in mixed-voltage logic systems.
For engineers reviewing the NC7WZ38K8X-L22236 datasheet, pinout, applications, or equivalent options, key selection considerations include open-drain OR-tie capability, 1.65–5.5 V supply flexibility, input overvoltage tolerance, ultra-low propagation delay, and US8 package compatibility with JEDEC MO-187 variation CA.
Technical Context
The NC7WZ38K8X-L22236 implements two independent NAND gates with open-drain output stages, enabling wired-OR logic and I²C bus interfacing. Its inputs tolerate 5.5 V regardless of VCC, supporting 5 V-to-3.3 V or 5 V-to-1.8 V level translation without external components.
Propagation delays are specified down to 1.65 V (tPZL/tPLZ ≤ 9.6 ns), and the device enters high-impedance state when VCC = 0 V-ensuring safe power-down behavior. The patented noise/EMI reduction circuitry improves signal integrity in dense PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Range | 1.65 V to 5.5 V - enables single-supply operation across 1.8 V, 2.5 V, 3.3 V, and 5 V logic domains |
| tPD (Typ) | 2.2 ns at 5 V into 50 pF - supports >200 MHz toggle rates in critical timing paths |
| IOL (Max) | 24 mA at 3 V VCC - drives standard TTL loads and multiple CMOS inputs directly |
| Input Voltage Tolerance | Up to 5.5 V independent of VCC - eliminates level shifters in mixed-voltage interfaces |
| Output Type | Open-drain - allows wired-OR configuration and bidirectional bus applications like I²C |
| Power-Down Behavior | Inputs and outputs high-impedance when VCC = 0 V - prevents back-driving during hot-swap or partial power-down |
Pinout & Package
NC7WZ38K8X-L22236 is packaged in an 8-lead US8 (JEDEC MO-187, Variation CA), 3.1 mm wide surface-mount package with gull-wing leads. The package is RoHS-compliant, Pb-free, and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | A1 | First NAND gate input - accepts 0–5.5 V logic levels regardless of VCC |
| 2 | B2 | Second NAND gate input - electrically identical to A1; supports mixed-voltage interface |
| 3 | A2 | Second NAND gate input - paired with B2 for second gate function |
| 4 | GND | Ground reference - must be connected to system ground plane for stable operation |
| 5 | Y2 | Second NAND gate open-drain output - requires external pull-up for HIGH assertion |
| 6 | B1 | First NAND gate input - paired with A1 for first gate function |
| 7 | Y1 | First NAND gate open-drain output - supports wired-OR with other open-drain devices |
| 8 | VCC | Positive supply - powers internal logic; range 1.65–5.5 V; decoupling capacitor required |
Key Features
| Feature | Design Value |
|---|---|
| Ultra High Speed Propagation | 2.2 ns typical tPD at 5 V - reduces combinatorial delay in high-frequency control logic |
| Open-Drain Output Stage | Enables wired-OR and bidirectional bus use (e.g., I²C, SMBus) without additional transistors |
| Overvoltage-Tolerant Inputs | 5.5 V tolerant at any VCC from 1.65–5.5 V - simplifies interconnect between legacy 5 V and modern low-VCC subsystems |
| Low Static Power Dissipation | ICC ≤ 1 µA max over full temperature range - ideal for battery-backed or always-on monitoring circuits |
| Patented Noise/EMI Reduction | Integrated circuitry minimizes switching noise coupling - improves signal integrity in noise-sensitive analog-adjacent layouts |

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 |
|---|---|---|---|

FAQ
What is the maximum operating frequency supported by NC7WZ38K8X-L22236?
The NC7WZ38K8X-L22236 has a typical propagation delay of 2.2 ns at 5 V into 50 pF, supporting theoretical toggle frequencies above 200 MHz. However, actual maximum operating frequency depends on load capacitance, supply voltage, and PCB layout; for reliable 100 MHz clocked logic, derate to ≤150 MHz with proper termination and decoupling.
Does NC7WZ38K8X-L22236 support I²C bus operation?
Yes, NC7WZ38K8X-L22236 supports I²C bus operation due to its open-drain outputs and 5.5 V input tolerance. When configured as a wired-OR logic element with external pull-ups, it can implement address decoding or interrupt arbitration on standard 3.3 V or 5 V I²C buses without level-shifting components.
Can NC7WZ38K8X-L22236 be used with a 1.8 V supply?
Yes, NC7WZ38K8X-L22236 is fully specified from 1.65 V to 5.5 V. At 1.8 V, it delivers tPZL/tPLZ ≤ 9.6 ns (−40°C to +85°C), VIH = 0.65 × VCC, and VOL ≤ 0.24 V at 4 mA sink - making it suitable for low-voltage portable and battery-powered logic interfacing.
Is NC7WZ38K8X-L22236 pin-compatible with older LCX-series NAND gates?
NC7WZ38K8X-L22236 matches LCX performance at 3.3 V but uses a different pinout than standard 8-pin SOIC LCX devices. It is not pin-compatible with 74LCX00; however, its US8 footprint is compatible with other TinyLogic UHS dual-gate variants sharing the same 8-lead US8 package outline.
What is the thermal resistance (θJA) of NC7WZ38K8X-L22236 in its US8 package?
The NC7WZ38K8X-L22236 in the US8 package has a junction-to-ambient thermal resistance (θJA) of 250°C/W under standard JEDEC test conditions. This value assumes a 1-inch² copper pad with two vias; actual thermal performance improves with enhanced PCB copper area and thermal vias.
