FST3244WM

Overview

The FST3244WM is an octal bus switch manufactured by Fairchild Semiconductor, providing eight bits of high-speed CMOS TTL-compatible switching. It utilizes a standard '244 pin-out configuration within a 20-SOIC package (0.295 inch width). The device features low on-resistance and contributes minimal propagation delay, limited only to the RC delay of the typical on-resistance. It operates as a signal switch suitable for data transmission and telecommunications applications.
