NC7SZ38FHX

Overview

The NC7SZ38FHX is a single-channel, two-input NAND gate from the TinyLogic UHS series manufactured by onsemi. It features an open-drain output configuration and operates within a supply voltage range of 1.65 V to 5.5 V. The device supports a maximum low-level output current of 32 mA and exhibits a maximum propagation delay of 4.3 ns at 5 V with a 50 pF load. It functions reliably across an extended temperature range of -40°C to +85°C and utilizes a compact 6-MicroPak2 surface-mount package.

Feature Summary

• Open-drain output capability for flexible interfacing
• Ultra-high-speed CMOS technology for minimal propagation delay
• Wide operating voltage range supporting multiple logic standards

Applications

• Portable consumer electronics requiring small form factors
• Battery-powered devices utilizing low-voltage operation
• High-density digital logic circuits in mobile applications

Procurement Notes

Verify the manufacturer designation carefully, as this component was originally developed by Fairchild Semiconductor and is now produced by onsemi following their acquisition. Confirm that the specific ordering suffix matches the required tape-and-reel packaging format. Ensure compliance with RoHS3 directives and check for any relevant Product Change Notices regarding assembly or material declarations before finalizing procurement specifications.

Selection Notes

Select this component when an open-drain NAND function is required in space-constrained designs. The MicroPak2 package offers a significant footprint reduction compared to standard SC-70 packages. Verify that the system design accommodates the open-drain nature of the output, which necessitates an external pull-up resistor to achieve a high logic state. Ensure the application voltage remains within the specified 1.65 V to 5.5 V operational limits.

Part Context

This part belongs to the NC7SZ family of TinyLogic ultra-high-speed CMOS gates. These components are designed to replace older discrete logic solutions in modern portable electronics. The NC7SZ38 specifically provides a two-input NAND function, serving as a fundamental building block for complex digital logic networks where speed and size are critical constraints.
