The MC74ACT257MELG is an integrated circuit (IC) component that belongs to the ACT family of devices. It is a quad 2-input multiplexer with 3-state outputs. Let's dive into its key features and functionalities.
1. Mux Functionality: The MC74ACT257MELG is primarily designed as a multiplexer (mux). It has four independent 2-input multiplexers, allowing the selection of one out of four data input lines to be routed to a single output line.
2. 3-State Outputs: This IC component features 3-state outputs. It means that the outputs can be in three different states - high (1), low (0), or in the high-impedance state. The high-impedance state allows multiple outputs to be connected together without causing any interference.
3. TTL Compatibility: The prefix "ACT" indicates that the MC74ACT257MELG is designed for compatibility with TTL (Transistor-Transistor Logic) logic levels. This feature ensures seamless integration with other TTL-compatible devices in a circuit.
4. Wide Operating Voltage Range: The IC can operate within a wide range of supply voltages, specifically from 4.5V to 5.5V. This flexibility makes it suitable for various applications and power supply configurations.
5. Low Power Consumption: The MC74ACT257MELG is designed to consume low power while maintaining excellent performance
