Overview
The 74LVC3G17DC-Q100H is a triple non-inverting buffer integrated circuit produced by Nexperia USA Inc. This device is part of the 74LVC family and is designed to provide three independent non-inverting buffers with Schmitt trigger inputs. It is particularly useful in applications requiring signal conditioning and noise immunity, as it can transform slowly changing input signals into sharply defined, jitter-free output signals.
The 74LVC3G17DC-Q100H is qualified to the Automotive Electronics Council (AEC) standard Q100 (Grade 1), making it suitable for use in automotive and other demanding environments. The device operates over a wide voltage range from 1.65 V to 5.5 V and is compatible with both 3.3 V and 5 V logic levels, making it an excellent choice for mixed-voltage systems.
