FST3244WMX

Signal Switches, Multiplexers, Decoders Overview

The FST3244WMX is an 8-bit bus switch manufactured by onsemi, housed in a 20-lead Thin Shrink Small Outline Package (TSSOP). It operates within a supply voltage range of 4.0 V to 5.5 V and supports an operating temperature range from -40°C to +85°C. The device features two independent four-bit switches with separate output enable inputs (/OE1 and /OE2), providing low on-resistance and minimal propagation delay for high-speed data routing.
