SN74AHC158PWR

Signal Switches, Multiplexers, Decoders Overview

The SN74AHC158PWR is a quadruple 2-line to 1-line data selector/multiplexer from the Texas Instruments AHC logic family. It operates within a supply voltage range of 2 V to 5.5 V and features a common strobe input that forces all outputs high when active. The device provides inverted data routing for four-bit words selected from two sources. It utilizes a TSSOP-16 surface-mount package and supports an operating temperature range from -40°C to +85°C.
