Overview
The NC7S14M5, produced by onsemi (formerly Fairchild Semiconductor), is a high-performance CMOS inverter with a Schmitt Trigger input. This device is part of the TinyLogic HS series, known for its advanced Silicon Gate CMOS fabrication, which ensures high speed and low power operation over a broad VCC range. The NC7S14M5 is designed to provide hysteresis between the positive-going and negative-going input thresholds, thereby improving noise margins. It is available in several compact package options, including SOT23-5, SC-74A, SC-88A, and MicroPak™ leadless packages, making it suitable for space-constrained applications.
