Overview
The SN74V225-7PAG is a synchronous first-in, first-out (FIFO) memory integrated circuit manufactured by Texas Instruments. It features an organization of 1024 words by 18 bits, providing a total storage capacity of 18 kbit. The device operates with a maximum clock frequency of 133 MHz and offers a typical access time of 5 ns. It is designed for unidirectional data transfer and supports programmable flags. The component is housed in a 64-pin Thin Quad Flat Pack (TQFP) package measuring 10x10 mm.
Feature Summary
- Synchronous FIFO architecture supporting high-speed data buffering
- Programmable status flags for flow control management
- Unidirectional data bus configuration
- CMOS technology for low power consumption
Applications
- Digital signal processing data buffering
- High-speed interface synchronization between asynchronous systems
- Data acquisition system temporary storage
- Communication protocol conversion buffers
Procurement Notes
Verify the specific suffix '7' indicates the 133 MHz speed grade and 5 ns access time variant. Confirm the 'PAG' suffix corresponds to the 64-TQFP package type. Check current lifecycle status as this series may be discontinued or subject to last-time buy notices. Ensure compatibility with 3.3 V logic levels specified for the SN74V family.
Selection Notes
Select this part when a 1024 x 18 word depth is required for synchronous data buffering. The 133 MHz performance suits applications needing fast data throughput. Compare against other SN74V225 variants if different depths or speeds are needed. Verify that the 18-bit data width matches the system bus requirements without additional multiplexing.
Part Context
This component belongs to the SN74V225 series of synchronous FIFO memories from Texas Instruments. The series includes variants with different depths such as 512, 1024, 2048, and 4096 words, all maintaining the 18-bit data width. The SN74V225-7PAG specifically represents the 1024-word depth version within this family.
Replacement Considerations
Direct substitutes include other SN74V225 variants with identical pinouts but different speeds or depths, such as SN74V225-15PAG. Cross-reference with SN74AVC225 series for improved performance, noting potential voltage level differences.
