NC7WZ38L8X

Overview

The NC7WZ38L8X is a dual 2-input NAND gate from the TinyLogic UHS series, fabricated using advanced CMOS technology. It features an open-drain output stage suitable for wired-OR applications. The device operates over a broad supply voltage range of 1.65V to 5.5V and achieves ultra-high speed with a typical propagation delay of 2.2 ns into 50 pF at 5V VCC. It provides high output sink drive capability of 24 mA at 3V VCC while maintaining low static power dissipation.

Feature Summary

• Open-drain output stage facilitates wired-OR logic configurations
• Ultra-high speed performance with minimal propagation delay
• Broad operating voltage range supporting 1.65V to 5.5V
• Overvoltage tolerant inputs enable safe 5V to 3V translation

Applications

• High-speed data bus switching
• Memory module address/data line buffering
• Portable equipment logic circuits
• Consumer electronics signal processing

Procurement Notes

Verify the manufacturer origin, as Fairchild Semiconductor was acquired by onsemi. Confirm the package type matches the specific suffix (L8X indicates MicroPak leadless). Ensure RoHS compliance status aligns with current environmental regulations. Check datasheet revisions for any parameter updates or pinout changes before final integration.

Selection Notes

Select this component when open-drain outputs are required for multi-driver bus architectures. The wide voltage range allows compatibility with both 1.8V and 5V systems. Consider the MicroPak package for space-constrained designs requiring leadless soldering. Verify input tolerance levels if interfacing directly with higher voltage sources without level shifting.

Part Context

This part belongs to the TinyLogic UHS family, designed for ultra-high speed and low power consumption. It replaces older LCX series devices in many applications due to improved speed characteristics. The NC7WZ38 variant specifically offers NAND functionality with open-drain outputs, distinguishing it from standard push-pull logic gates in the same series.

Replacement Considerations

NC7WZ38K8X: Identical logical function but utilizes US8 surface mount package instead of MicroPak.
