74AHC257PW,112

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74AHC257PW,112 is a quad 2-input multiplexer with 3-state outputs housed in a TSSOP16 package. It operates within a supply voltage range of 2.0 V to 5.5 V and features overvoltage tolerant inputs up to 5.5 V. The device includes Schmitt-trigger action on all inputs for noise immunity and balanced propagation delays. Static characteristics specify input leakage current at 0.1 μA maximum (25 °C) and output low voltage at 0.36 V maximum (IO = 8.0 mA, VCC = 4.5 V). Dynamic performance indicates typical propagation delay from data input to output of 4.2 ns at 3.3 V with 15 pF load.
