SN74ABT7819-20PN TI FIFO Memory | 80-LQFP (12x12) | 20ns Access, 256x9

Product Overview

The SN74ABT7819-20PN is a high-performance 256-word by 9-bit FIFO memory device from Texas Instruments, designed for buffering and data flow management in high-speed digital systems. Housed in an 80-pin LQFP package (12x12 mm), it operates with a typical access time of 20 ns and supports bidirectional asynchronous data transfer. The device features dual-port architecture with independent read and write pointers, making it ideal for applications requiring temporary data storage and rate matching between different clock domains.
