Overview
The SN74ACT7200L25DVR is an asynchronous FIFO memory IC manufactured by Texas Instruments. It features a 256 x 9 bit organization, providing 256 words of storage with 9-bit width per word. The device utilizes the ACT logic series for high-speed performance and low power consumption. It is housed in a 28-pin SOIC (Small Outline Integrated Circuit) package, suitable for surface-mount applications. The component supports standard TTL-compatible inputs and offers three-state outputs for bus-oriented designs.
Feature Summary
- Asynchronous operation allows independent read and write clock domains
- Three-state outputs facilitate connection to shared data buses
- ACT logic series ensures high speed with low power dissipation
Applications
- Data buffering between different clock domains
- Interface bridging in high-speed digital systems
- Temporary data storage in communication protocols
Procurement Notes
Verify the exact suffix 'L25' corresponds to the specific speed grade and package variant required for your design. Confirm the pinout matches the 28-pin SOIC footprint. Ensure the asynchronous nature aligns with your system timing requirements. Check for RoHS compliance status if mandated by your project specifications.
Selection Notes
Select this component when asynchronous data transfer is required without a common clock signal. The 9-bit width accommodates parity bits or extended data formats. Consider the ACT series benefits for noise immunity and speed compared to older LS or HC families. Ensure the 256-word depth meets your buffer size constraints.
Part Context
This part belongs to the Texas Instruments SN74ACT family of logic devices. It is categorized under asynchronous FIFOs within the memory IC segment. The device complements other ACT-series components for complete system integration. It serves as a critical interface element in complex digital architectures requiring data rate matching.
Replacement Considerations
Check for direct cross-references from other manufacturers offering identical 256x9 asynchronous FIFOs in SOIC-28 packages. Verify pin compatibility before substitution. Ensure equivalent propagation delays and electrical characteristics are maintained.
