General description
The 74ALVC14 is a high-performance, low-power, low-voltage, Si-gate CMOS device and
superior to most advanced CMOS compatible TTL families.
The 74ALVC14 provides six inverting buffers with Schmitt-trigger action. It is capable of
transforming slowly changing input signals into sharply defined, jitter-free output signals.
