SN74ABT7820-25PN TI FIFO Memory | 80-LQFP（12X12） | 25ns, 512x18

Product Overview

The SN74ABT7820-25PN is a high-performance 512-word by 18-bit bidirectional FIFO memory from Texas Instruments, designed for high-speed data buffering and synchronization. Operating at a 25ns access time, it supports clock frequencies up to 40 MHz. The device is housed in an 80-pin LQFP (12x12mm) package, making it suitable for space-constrained applications. It features independent read and write clocks, allowing asynchronous data transfer between different clock domains. The FIFO is ideal for applications requiring temporary data storage, rate buffering, and bus matching.
