The TC74VHC14 series is a high‑speed CMOS Schmitt‑trigger inverter fabricated with silicon‑gate C2MOS technology. It offers TTL‑like speed with low CMOS power dissipation and includes input protection for 0 V to 5.5 V signals, making it suitable for level‑shifting and line‑receiver applications.
The document lists absolute maximum ratings, recommended operating conditions, DC and AC electrical characteristics, noise performance, and mechanical data for the three package variants (SOP‑14, SOL‑14, TSSOP‑14). Key parameters such as supply voltage range, propagation delay, hysteresis voltage, and power dissipation are detailed for designers.
