The DM74S571N is a high-speed Schottky TTL programmable ROM (PROM) organized as 512 words by 4 bits. It's designed for use in microprogramming, code conversion, and lookup table applications.

Applications:

• Microprogramming in CPUs and controllers
• Code converters
• Lookup tables for mathematical functions
• Character generators
• Sequential logic circuits

Features:

• High-speed Schottky TTL technology
• Organized as 512 words x 4 bits
• Typical address access time of 40 ns
• Low input loading
• PNP inputs reduce input loading
• Open-collector outputs for expansion
• Fully TTL compatible

Benefits:

• Fast access time enables high-performance systems.
• Programmability allows for flexible design changes.
• TTL compatibility simplifies integration with other TTL devices.
• The device allows for easy expansion, accommodating more complex designs.
• Open collector outputs provide versatility in wiring.

Additional Details:

The DM74S571N is packaged in a 16-pin dual-in-line package (DIP). It operates from a single 5V power supply. Programming is achieved by selectively fusing the internal links. The device is designed for operation over the commercial temperature range (0°C to +70°C).
