ON Semiconductor MC74AC257DR2G Multiplexer

The MC74AC257DR2G from ON Semiconductor is a high-performance, quad 2-input multiplexer with 3-state outputs. This integrated circuit (IC) is designed to select one of two data sources for each output based on the state of a common data select input. It is a versatile component that can be used in a wide range of digital applications, including data routing, signal gating, and function generation.

This multiplexer operates at a voltage range of 2V to 6V, making it compatible with TTL logic levels while also allowing it to interface with many other standard logic families. The MC74AC257DR2G is characterized by its fast switching speeds and low power consumption, which are critical for high-speed data processing and battery-powered devices.

Key Features:

• Logic Type: Multiplexer
• Number of Circuits: 4
• Number of Inputs: 2 per multiplexer
• Number of Outputs: 1 per multiplexer
• Output Type: 3-State
• Voltage - Supply: 2V to 6V
