Overview
The SN74ACT7200L25NP is an asynchronous FIFO memory IC manufactured by Texas Instruments. It features a memory configuration of 256 x 9 bits, providing a total capacity of 2.25K bits. The device operates with a typical access time of 25ns and supports a data rate of 28.5MHz. It is designed for commercial temperature ranges from 0°C to 70°C and utilizes a 28-pin DIP package. The component includes retransmit capability and functions as a unidirectional buffer.
Feature Summary
- Asynchronous operation for independent read and write clock domains
- Retransmit capability for reliable data handling
- Unidirectional buffering architecture
Applications
- Data buffering between asynchronous systems
- Interface bridging in digital communication circuits
- Temporary storage in high-speed data acquisition systems
Procurement Notes
Verify the exact datasheet version and manufacturer specifications before procurement. Confirm package type is 28-DIP and operating temperature range meets commercial requirements. Ensure compatibility with 5V supply voltage. Check for moisture sensitivity level 3 handling requirements during storage and assembly.
Selection Notes
Select this component when asynchronous FIFO functionality with 256x9 depth is required. Consider the 25ns access time and 28.5MHz data rate for speed suitability. Verify that the 28-pin DIP package fits the board layout constraints. Ensure the commercial temperature range aligns with the application environment.
Part Context
This part belongs to the SN74ACT series of logic components, specifically within the FIFO memory category. It is designed for general-purpose digital applications requiring temporary data storage between asynchronous clock domains. The ACT series offers advanced technology characteristics suitable for modern digital systems.
Replacement Considerations
Check for direct pin-compatible substitutes within the SN74ACT family. Verify equivalent memory depth (256x9) and access times. Ensure similar package dimensions and electrical characteristics for seamless integration without circuit redesign.
