SN74AHCT125DBR - Quad Bus Buffer Gates with 3-State Outputs

The SN74AHCT125DBR from Texas Instruments is a high-performance, quadruple bus buffer gate featuring 3-state outputs that are capable of driving highly capacitive or relatively low-impedance loads. Designed for operation over a broad voltage range of 4.5V to 5.5V, this device is optimized for 5V systems. It is characterized for operation from -40°C to 85°C, making it suitable for a wide array of commercial applications.

With its 3-state output stage, the SN74AHCT125DBR ensures that the outputs are effectively disconnected and will not load the bus when the output-enable (OE) input is high. This feature is particularly useful in bidirectional bus applications and where multiple outputs must interface with a common bus without contention.

The SN74AHCT125DBR implements the industry-standard AHCT logic, which provides TTL-compatible input thresholds, ensuring compatibility with a wide range of digital circuits. The device is fabricated using silicon-gate CMOS technology, which offers the inherent benefits of CMOS—low quiescent power and reduced noise susceptibility.

This product comes in a DBR package, which is a small-outline integrated circuit with 14 pins. The package is designed for space-saving on PCBs, and its small form factor is ideal for compact electronic assemblies. The SN74AHCT125DBR is RoHS compliant and is committed to environmental sustainability.

Key features of the SN74AHCT125DBR include:

• Operating Voltage Range: 4.5V to 5.5V
• High-Drive Outputs (-32-mA IOH, 64-mA IOL)
• 3-State Outputs for Bus-Oriented Applications
• TTL-Compatible Input Logic Levels
• Low Power Consumption
• ESD Protection Exceeds JESD 22

Applications for the SN74AHCT125DBR span across a variety of sectors including telecommunications, computing, industrial controls, and consumer electronics. Its robust design and high drive capability make it an excellent choice for interfacing with high-capacity memory modules, microprocessors, and as a buffer for data transmission lines.

Overall, the SN74AHCT125DBR from Texas Instruments is a versatile and reliable component that provides the functionality and performance required for complex digital systems, ensuring signal integrity and system reliability.
