74AHC257D,112

Signal Switches, Multiplexers, Decoders Overview

The 74AHC257D,112 is a quad 2-input multiplexer with 3-state outputs manufactured by Nexperia. 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 utilizes CMOS technology for low power dissipation and high noise immunity. Inputs include Schmitt-trigger actions, and the data path is non-inverting. Latch-up performance exceeds 100 mA per JESD 78 Class II Level A. ESD protection meets ANSI/ESDA/JEDEC JS-001 class 2 (HBM > 2000 V) and JS-002 class C3 (CDM > 1000 V). It is specified for ambient temperatures from -40 °C to +125 °C.
