SN74ABT7819A-20PN TI FIFO Memory | 80-LQFP (12x12) | 20ns Access, 256x18

Product Overview

The SN74ABT7819A-20PN is a high-performance 256-word by 18-bit bidirectional FIFO memory from Texas Instruments, designed for asynchronous data transfer between two independent clock domains. Housed in an 80-pin LQFP (12x12 mm) package, this device operates with a typical access time of 20 ns, making it suitable for high-speed data buffering applications. It features dual-port architecture with separate read and write clocks, allowing simultaneous read and write operations. The FIFO depth and width are configurable via dedicated control pins, providing flexibility for various system designs.
