The SN74LS257BN is an Integrated Circuit (IC) component that belongs to the 74LS family of quadruple 2-line to 1-line data selectors or multiplexers. It is designed to provide a high-level integration and flexibility in digital circuit designs. Below are some key features and an overview of the SN74LS257BN IC component:
1. Overview:
- The SN74LS257BN is a 16-pin DIP (Dual Inline Package) IC component.
- It consists of four 2-line to 1-line data selectors or multiplexers in a single chip.
- Each data selector has two data inputs (A and B), one selection input (S), and one output (Y).
- The selection input (S) determines which data input is routed to the output.
- The output Y provides the selected data input signal.
2. Key Features:
- Fast Switching Speed: The SN74LS257BN has a fast propagation delay, which allows for rapid data selection.
- Low Power Consumption: This IC component operates on low power, making it suitable for battery-powered devices.
- Wide Operating Voltage: It can operate at a wide voltage range of 4.75V to 5.25V, compatible with standard TTL (Transistor-Transistor Logic) logic levels.
- High Noise Immunity: The IC has built-in Schmitt-trigger inputs, providing excellent noise immunity and stable operation
