The Texas Instruments SN54LS222W is a 16x4 asynchronous FIFO buffer with TTL compatibility. This device offers a memory density of 64 bits, organized as 16 words by 4 bits. Featuring a 20-pin Ceramic FlatPack (CDFP20) package with dual-position flat terminals on a 1.27mm pitch, it supports surface mounting. The SN54LS222W operates asynchronously, allowing for independent clocking of read and write operations. It includes an output enable function. Designed for robust operation, it has a wide operating temperature range from -55°C to 125°C and operates from a nominal 5V supply (4.5V to 5.5V). Typical applications for this component include data buffering and signal synchronization in industrial and military systems. The SN54LS222 series is known for its high-speed performance and reliable asynchronous operation.
