Onsemi MC74AC125DR2G Environmental and export classification status description

The Onsemi MC74AC125DR2G is a quad buffer/driver with 3-state outputs. This IC is designed to provide high-speed performance while maintaining low power consumption and is part of the 74AC family of logic devices. It operates with a wide supply voltage range and is suitable for various digital logic applications. Functions - Quad Buffer/Driver: Contains four separate buffers/drivers that can independently drive outputs. - 3-State Outputs: Each output can be in one of three states: high, low, or high-impedance (off), allowing for flexible digital signal routing. - High-Speed Performance: Suitable for applications requiring fast signal transitions. - Voltage Compatibility: Compatible with a wide range of supply voltages. Applications - Data Bus Isolation: Used for isolating sections of data buses in digital circuits. - Logic Level Shifting: Can be used to convert signals between different voltage levels in mixed-voltage systems. - Signal Conditioning: Buffers signals from microcontrollers or processors before they are sent to further processing stages. - Interfacing: Acts as an interface between logic families or along communication lines. Alternative Parts - 74HC125: A similar buffer/driver that operates at a different voltage standard and has slightly different electrical characteristics. - 74LVC125: A low-voltage version of the buffer that operates with 1.8V logic levels. - MC74HCT125: A variant that operates with TTL-level inputs for improved compatibility with older logic families. Embedded Modules While the MC74AC125DR2G is primarily an IC, it can be part of the following embedded solutions: - Microcontroller Development Boards: Integrated into various platform development boards for signal buffering. - FPGA/ASIC Design: Used in custom chip designs for signal driving and isolation purposes. - Communications Modules: Implemented in circuit designs for communications and data protocols.
