The SN74LS251NS is a popular integrated circuit component manufactured by Texas Instruments. It is categorized as a multiplexer/demultiplexer with 8 channels ??i.e., it can handle eight separate digital signals. This IC is widely used in digital systems for data routing and selection purposes. Now, let's explore the key features and functionalities of the SN74LS251NS component:
1. Multiplexer/Demultiplexer (MUX/DEMUX): The primary function of this IC is to operate as a multiplexer or a demultiplexer. It can select one out of eight input lines using a 3-bit binary code on the common select inputs. Additionally, it can be configured as a demultiplexer by reversing its operation.
2. TTL Logic: The SN74LS251NS is built using TTL (Transistor-Transistor Logic) technology. It operates on a supply voltage range of 4.75V to 5.25V, making it compatible with various TTL-based digital systems.
3. Low Power Consumption: This IC is designed to consume low power, making it energy-efficient and suitable for battery-powered devices or applications where power consumption is a concern.
4. High-Speed Operation: With a propagation delay time of around 15 ns, the SN74LS251NS is well-suited for high-speed digital circuits. It ensures efficient data transmission and minimal delays in signal routing
