FIFOs Memory ICs

SN74ACT7881-20FN Description

The SN74ACT7881-20FN is a synchronous FIFO memory IC designed by Texas Instruments, featuring a memory size of 18K (1K x 18) and an access time of 13ns. This IC operates at a data rate of 50MHz and is suitable for applications requiring high-speed data buffering and storage. The device is housed in a 68-pin PLCC package, making it ideal for surface-mount applications. It operates within a supply voltage range of 4.5 V to 5.5 V and has a maximum supply current of 400µA. The SN74ACT7881-20FN supports programmable flags, which enhance its flexibility in various applications. However, it does not support First Word Fall Through (FWFT) or retransmit capabilities. The operating temperature range is 0°C to 70°C, and it is compliant with REACH and ROHS3 standards. The moisture sensitivity level (MSL) is 3, indicating a 168-hour exposure limit. This product is currently marked as obsolete by the manufacturer.
