What are the key features of SN74ACT7805-25DLR?
- 256 x 18-bit synchronous FIFO organization for 18-bit wide data paths
- 15 ns maximum access time with 40 MHz maximum clock frequency
- 4608-bit total memory density for buffering burst data streams
- 56-pin SOIC package supporting wide 18-bit bus connections
- Synchronous read and write operations with independent clocks
- Full and empty flag outputs for flow control handshaking
- TTL-compatible inputs and outputs for ACT-family logic interfacing
What is SN74ACT7805-25DLR used for?
SN74ACT7805-25DLR is used in high-speed digital systems for buffering 18-bit wide data between processors and peripherals running at different clock rates, such as DSP-to-memory interfaces and parallel bus bridges in telecommunications equipment. It suits video frame synchronization circuits and printer data spoolers where burst data must be stored temporarily before processing. FIFO depth of 256 words provides adequate buffering for burst transfers on 40 MHz ACT logic boards.

Frequently Asked Questions
Which design use cases are a practical fit for SN74ACT7805-25DLR?
SN74ACT7805-25DLR is a Integrated Circuit from Texas Instruments suited to embedded systems, industrial electronics, communication equipment, test fixtures, and production BOM sourcing. The 56 pins detail helps engineers confirm schematic fit, interface allocation, and sourcing suitability before BOM approval.
How should engineers check package compatibility for SN74ACT7805-25DLR during layout review?
Use the Small Outline Packages package information together with 56 pins when comparing footprints, assembly drawings, and mating or socket constraints. This reduces layout risk before prototype or production purchasing.
What should procurement keep aligned when cross-referencing SN74ACT7805-25DLR against alternates?
Cross-reference checks should preserve the manufacturer, Integrated Circuit function, package style, lifecycle status, and at least one key parameter such as 74A. Matching these details lowers substitution risk across 1 approved BOM.
