Quad 2-input NAND gate in S-series TTL
The SN74S00NS is a quad 2-input NAND gate from Texas Instruments' S series, built on Schottky TTL logic. It's a workhorse logic element for high-speed gating in legacy 5 V digital systems.
Package and reworkability
Supplied in a Bulk package — loose tubes or trays, not tape-and-reel. The SOIC-14 footprint is straightforward to hand-solder or rework under a hot-air station; the 1.27 mm pitch leaves room for probe points and inspection. Pin 1 is clearly marked on the package body, so orientation is unambiguous during manual placement or reflow.
