Product Description

The 74LS251 features a common output enable (OE) input which, when high, forces the output into a high-impedance state, allowing for the multiplexed output to be effectively disconnected from the circuit. This feature is particularly useful when multiple 74LS251 devices are connected to a common bus, enabling only one device at a time to drive the bus.

Manufactured with ON Semiconductor's high-grade technology, the 74LS251 guarantees excellent performance with a robust design. The IC comes in a standard 16-pin DIP (Dual In-line Package) or SOP (Small Outline Package), making it easy to integrate into a wide range of electronic systems.

The ON Semiconductor 74LS251 multiplexer is a reliable and efficient solution for designers looking to manage multiple data sources within their digital circuits. Its combination of high-speed operation, low power consumption, and versatile output state control makes it an excellent choice for complex electronic designs.
