TC74VHC27F/FT/FK is a ultra-high speed CMOS 3-input NOR gate produced by Toshiba. This product has the characteristics of high speed, low power consumption, high noise margin, power down protection function for all inputs, balanced delay time, wide operating voltage range, the same pin connection and the same function as 74ALS27.
The TC74VHC27 series is a high‑speed CMOS triple 3‑input NOR gate that uses Toshiba's silicon‑gate OMOS technology. It offers low static power (Ioo = 2 nA) and fast propagation delay (tpd ≈ 1 ns) while providing full‑input power‑down protection.
The device is supplied in SOP14, TSSOP14 and VSSOP14 packages, with detailed absolute maximum ratings, operating ranges, DC characteristics, and package dimensions documented for designers. This manual is written in Japanese.
