The 74AC257PC is a Quad 2-to-1 multiplexer IC component. It is a part of the 74 series of logic integrated circuits and is widely used in digital and computer applications. Here is an overview of the key features of this IC:
1. Quad 2-to-1 Multiplexer: The 74AC257PC consists of four independent 2-input multiplexers. Each multiplexer can select one of the two input signals based on the control inputs, producing a single output.
2. Advanced CMOS Technology: The IC is fabricated using advanced CMOS technology, specifically the AC family, which provides reliable performance, high speed, and low power consumption. It operates with a supply voltage ranging from 2V to 6V.
3. Inputs and Outputs: The IC has two input data signals per multiplexer, along with a select input that controls which data input will be selected. The output is a single logic-level signal. The inputs and outputs are compatible with both digital 74 series and 74LS series ICs.
4. Buffering and Noise Immunity: The 74AC257PC features inputs that have buffered outputs. It has a high noise immunity and is designed to be resistant to various electrical noises and interferences.
5. Voltage compatibility: The IC is compatible with TTL and Cmos voltage levels, making it suitable for interfacing with a wide range of digital systems
