The DM74ALS02 is a quad 2-input NOR gate from Fairchild Semiconductor. The device contains four independent gates, each of which performs the logic NOR function. The DM74ALS02 has a switching specification at 50 pF and switching specifications guaranteed over full temperature and VCC range. It is available in Tape and Reel and is pin-compatible with Schottky and low power Schottky TTL counterpart.
The DM74ALS02 is a quad 2‑input NOR gate fabricated with Fairchild's advanced oxide‑isolated, ion‑implanted Schottky TTL process. It offers four independent gates that are functionally and pin‑for‑pin compatible with standard Schottky TTL devices.
