74LS151 8-Line to 1-Line Data Selector and Multiplexer (DIP-16)

The 74LS151 is a high-speed monolithic data selector/multiplexer that routes one of eight input data lines to a single output. By utilizing a 3-bit binary selection code, the device can effectively switch between various digital signal sources, making it a cornerstone for data routing and signal steering applications. A unique feature of this IC is that it provides both the true output (Y) and its complement (W) simultaneously, which simplifies the design of complex logic circuits and reduces the need for external inverters. The active-low strobe input allows the outputs to be forced into a known state, facilitating the cascading of multiple multiplexers to expand the number of inputs. It is commonly used in parallel-to-serial conversion, function generators, and Boolean logic implementation in industrial control and computer systems.

Key Features:

Features complementary outputs (Y and W) providing both true and inverted data.

Includes an active-low strobe (G) input for enabling or disabling the chip.

Fast switching performance with a typical propagation delay of 9 nanoseconds.

Low power consumption of 30 milliwatts typical for the Low Power Schottky family.

Fully compatible with most standard TTL and CMOS logic systems.
