The 74F257APC belongs to the category of integrated circuits (ICs) and specifically falls under the family of multiplexers/demultiplexers.
This IC is commonly used in digital electronics for data multiplexing and demultiplexing applications. It allows multiple input signals to be selected and routed to a single output or vice versa.
The 74F257APC is available in a 16-pin plastic dual in-line package (PDIP). It is typically sold in reels or tubes containing multiple units, with quantities varying based on the supplier and customer requirements.
The 74F257APC has a total of 16 pins, each serving a specific function. The pin configuration is as follows:
The 74F257APC offers the following functional features:
The 74F257APC operates based on the principles of digital logic. It uses the control inputs (A0-A3) and enable input (G) to select one of the four input channels and route it to the corresponding output channel (Y0-Y4). The selected input is determined by the binary combination of the control inputs. When the enable input (G) is active, the output reflects the selected input; otherwise, the outputs are in a high-impedance state.
The 74F257APC finds applications in various digital systems and electronic devices, including but not limited to:
