DM74ALS03B is a Quad 2-Input NAND Gate with Open Collector Outputs manufactured by Fairchild Semiconductor Corporation. The device contains four independent gate circuits, each of which performs the logic NAND function.
The document describes the DM74ALS03B, which contains four independent gates performing the logic NAND function. These devices utilize an advanced oxide-isolated, ion-implanted Schottky TTL process and are pin-compatible with standard Schottky TTL counterparts. The open-collector outputs require external pull-up resistors for proper logical operation.
The datasheet provides comprehensive technical data including absolute maximum ratings, recommended operating conditions, electrical characteristics such as propagation delay times, and physical dimensions for both SOIC (M14A) and PDIP (N14A) packages. It also includes a life support policy notice regarding the use of these components in critical medical applications.
