Fairchild Semiconductor FST3345 8-Bit Bus Switch Datasheet
The Fairchild Semiconductor FST3345 is an 8-bit bus switch designed to provide high-speed, TTL-compatible switching between two ports. It features a low on-resistance that minimizes propagation delay and ground bounce noise, making it suitable for connecting inputs to outputs without signal degradation. The device operates in a flow-through mode with zero bounce and includes dual output enable inputs (OE and OE) for control.
