The 74AHC/AHCT00 are high-speed Si-gate CMOS devices and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard No. 7A. The 74AHC/AHCT00 provides the 2-input NAND function.
The Philips 74AHC00 and 74AHCT00 are high‑speed Si‑gate CMOS quad 2‑input NAND gates, pin‑compatible with low‑power Schottky TTL. They feature ESD protection, Schmitt‑trigger inputs and operate over a wide temperature range.
The document provides electrical characteristics, recommended operating conditions, pin configurations, ordering information and package options for both the AHC (CMOS‑level inputs) and AHCT (TTL‑level inputs) variants.
