The MC74LS125AD is a quad 3-state buffer manufactured by Freescale Semiconductor - NXP. This device is part of the LS family of low-power Schottky TTL logic, known for its relatively low power consumption and good speed. It contains four independent buffers with 3-state outputs, allowing them to be connected to a bus.

Applications

• Bus interfacing
• Memory address decoding
• Data buffering
• Line driving
• Data multiplexing

Features

• 3-State Outputs: Allows for connection to a bus system.
• Low Power Consumption: ICC = 6 mA (max)
• High Speed: tPD = 10 ns (typ)
• TTL Compatible Inputs and Outputs
• Fanout: 10 LSTTL Loads
• Operating Voltage: 4.75 V to 5.25 V

Benefits

• Bus Compatibility: 3-state outputs enable easy connection to bus systems.
• Low Power: Minimizes power consumption in digital circuits.
• High-Speed Operation: Supports fast data transfer.
• Quad Buffer: Four independent buffers in a single package.
• Enables Signal Isolation: 3-state outputs can isolate sections of a circuit.

Additional Details

The MC74LS125AD contains four independent buffers. Each buffer has an output enable (OE) input. When OE is low, the output is enabled and follows the input. When OE is high, the output is in a high-impedance state. The device is typically available in a 14-pin SOIC package. Storage Temperature Range: -65°C to +150°C.
