Overview

Description

The 74FCT257T is a high-speed quad 2-input multiplexer. The 74FCT257T has a common Output Enable (OE) input. When OE is high, all outputs are switched to a high-impedance state allowing the outputs to interface directly with bus-oriented systems. The 74FCT257T operates at -40C to +85C
