SN74ACT7881-20FN TI FIFO Memory | 68-PLCC (24.23X24.23) | 20ns Access, 512x9

Product Overview

The SN74ACT7881-20FN is a high-performance 512 x 9-bit FIFO (First-In, First-Out) memory device from Texas Instruments, designed for high-speed data buffering and flow control applications. It features a 20 ns access time and operates from a single 5V supply. The device is housed in a 68-pin PLCC package (24.23x24.23 mm) and offers bidirectional asynchronous read/write capability, making it ideal for interfacing between different clock domains or data rates.
