ON Semiconductor DM74LS257BN Product Overview

The DM74LS257BN is a high-performance, quadruple 2-line to 1-line data selector/multiplexer integrated circuit brought to you by ON Semiconductor, a trusted leader in innovative semiconductor solutions. This IC is designed to provide the reliability and efficiency needed in today's sophisticated electronic equipment.

The DM74LS257BN features four individual 2-line to 1-line multiplexers with 3-state outputs. This functionality allows for the selection of one of two data sources for each multiplexer, which can then be turned off completely to allow for the passage of signals from other devices. The 3-state outputs can interface directly with and drive data lines of bus-organized systems with ease. With a typical power dissipation of 95 mW and a wide operating voltage range of 4.75V to 5.25V, this device is designed for use in TTL logic systems.

The multiplexer circuits of the DM74LS257BN incorporate select inputs (A and B), an enable input (G\), and outputs (Y). When the enable input is high, the outputs are in a high impedance state, which means that the outputs do not interfere with the operation of other components on the bus.

With its versatility and ON Semiconductor's reputation for high-quality components, the DM74LS257BN is ideal for use in a wide range of applications such as data routing, memory selection, and bus arbitration. Its 16-pin DIP (Dual In-line Package) allows for easy integration into your existing designs.

For engineers and designers looking for a reliable data selector/multiplexer solution, the DM74LS257BN from ON Semiconductor offers a perfect blend of performance, power efficiency, and ease of use, making it a valuable component in any digital logic system.
