Nexperia 74AHC14D,118 Hex Schmitt Trigger Inverter, 14-Pin SO

The 74AHC14, 74AHCT14 is a high-speed Si-gate CMOS device and is pin compatible with Low-power Schottky TTL (LSTTL). The 74AHC14, 74AHCT14 provides six inverting buffers with Schmitt-trigger action. They are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals.
