The NTE74LS170 is a 4 x 4 Register File with Open-Collector Outputs from NTE Electronics. This device is a high-speed, low-power Schottky TTL circuit designed for use in memory and register applications.

Applications:

• Scratchpad memory
• Buffer storage
• Control memory
• Look-up tables
• Data storage in digital systems

Features:

• Organized as 4 words of 4 bits each
• Open-collector outputs for wired-OR expansion
• High-speed operation
• Low power consumption
• Expandable in both word and bit dimensions
• Multiple address enable inputs

Benefits:

• Flexibility: The open-collector outputs allow for wired-OR expansion, enabling larger memory arrays to be constructed.
• High performance: High-speed operation ensures fast data access and processing.
• Reduced power consumption: Low power consumption minimizes heat dissipation and reduces power supply requirements.
• Simplified system design: Expandability simplifies the design of larger memory systems.

Technical Specifications:

The NTE74LS170 operates from a 5V power supply. It has typical propagation delays in the range of 15 ns. The device is TTL compatible and can be easily interfaced with other TTL devices. The operating temperature range is typically from 0°C to +70°C. The open-collector outputs require external pull-up resistors.
