The IC component 54F251A/BEA is a 8-bit multiplexer/multiplexor with data storage capability, designed for use in digital systems and electronic devices. It is a part of the 54F series, which is a TTL (Transistor-Transistor Logic) family of integrated circuits.
The main function of the 54F251A/BEA is to select one of two 8-bit data inputs (A or B) and route it to the output based on the control inputs (S). It can be used as either a multiplexer or a demultiplexer, depending on the configuration.
Key features of the 54F251A/BEA include:
1. 8-bit Data Inputs: It has two separate 8-bit data inputs, labeled as A and B. These inputs can accept digital signals from external sources or other parts of the circuit.
2. Data Selection: The chip provides three control inputs, labeled as S0, S1, and S2. These inputs are used to select which input (A or B) is connected to the output. Various combinations of these control inputs allow for dynamic selection of data inputs.
3. Data Output: The chip has an 8-bit data output, labeled as Y. The selected input (A or B) is routed to this output, and it carries the same digital information as the selected input.
4. Enable Input: There is an additional enable input, labeled as G
