The MC74ACT125DR2 from onsemi is a quad non-inverting buffer from the 74ACT logic family. It features four channels with 3-State outputs, providing robust bus interfacing for 5V systems. Operating from 4.5V to 5.5V, it offers TTL-compatible inputs and CMOS outputs, with a balanced 24mA source and sink current. The 14-SOIC package is compact and suitable for standard PCB designs. This buffer is ideal for bus driving, level conversion, and signal conditioning in industrial and commercial applications, with a -40°C to 85°C temperature range.

  • TTL-Compatible Inputs: Allows direct interfacing with 3.3V logic, simplifying mixed-voltage designs.
  • High-Speed 74ACT Performance: Ensures minimal propagation delay for high-frequency signals.
  • 3-State Outputs: Enables bus sharing and multiplexing, critical for multi-device systems.
  • Wide Temperature Range (-40°C to 85°C): Suitable for industrial environments.

5V Bus Interfacing

Use the MC74ACT125DR2 to buffer data and address buses in 5V microcontroller systems. The 3-State outputs allow multiple peripherals to share the same bus, while the 24mA drive ensures signal integrity.

TTL-to-CMOS Level Conversion

With TTL-compatible inputs, this buffer can accept 3.3V logic signals and output 5V CMOS levels. This makes it useful for interfacing older TTL logic with newer CMOS devices.

Memory Address Buffering

Buffer address lines for SRAM or Flash memory in 5V embedded systems. The 4 channels can buffer a nibble or byte segment, and the high speed of 74ACT logic minimizes propagation delays.

Industrial Control Signal Conditioning

In industrial PLCs, use this buffer to condition signals from sensors or control lines. The -40°C to 85°C range ensures reliable operation in factory environments.

Backplane Driver for Legacy Systems

For legacy 5V backplane systems, this buffer provides the necessary drive strength and 3-State isolation for hot-swapping cards.

Test Equipment Output Buffering

In benchtop test equipment, use this buffer to drive output signals to external devices. The 3-State feature allows for disabling outputs during calibration.
