74AHC157PW,112

Signal Switches, Multiplexers, Decoders Overview

The Nexperia 74AHC157PW,112 is a quad 2-input multiplexer belonging to the AHC logic family. It selects four bits of data from two sources under the control of a common data select input (S). The enable input (E) is active LOW; when HIGH, all outputs are forced LOW. It operates with CMOS input levels and features balanced propagation delays. The device is specified for supply voltages between 2.0 V and 5.5 V, with an operating temperature range of -40 °C to +125 °C. It utilizes a TSSOP16 package.
