74LVC257AD,118

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74LVC257AD,118 is a quad 2-input multiplexer with 3-state outputs housed in a 16-lead SO plastic small outline package (SOT109-1). It operates on a single supply voltage ranging from 1.2 V to 3.6 V. The device features overvoltage tolerant inputs and outputs capable of handling up to 5.5 V, allowing direct interfacing with 5 V devices. Propagation delay ranges from 1.0 ns to 12.3 ns depending on the supply voltage and temperature conditions.
