CD74HC151EE4

Signal Switches, Multiplexers, Decoders Overview

The CD74HC151EE4 is a high-speed CMOS logic 8-input multiplexer manufactured by Texas Instruments. It operates within a supply voltage range of 2 V to 6 V and supports an extended temperature range from -55°C to 125°C. The device features three binary control inputs (A, B, C) and an active-low enable input (G). It provides both inverting (W) and non-inverting (Y) outputs. Packaged in a 16-pin PDIP format with dimensions of 19.31 mm by 6.35 mm, it offers balanced propagation delays and significant power reduction compared to LSTTL equivalents.
