SN74AHCT125DRG4 Quad Bus Buffer Gates with 3-State Outputs

The SN74AHCT125DRG4 is a high-performance, quad bus buffer gate integrated circuit from Texas Instruments, designed to provide high-speed, non-inverting buffer and line driver solutions for a wide range of applications. It features four independent buffer gates with 3-state outputs, making it an ideal choice for driving bus lines or buffer memory address registers.

Each gate of the SN74AHCT125DRG4 is equipped with a dedicated output enable (OE) input, which, when held high, puts the output in a high-impedance state. This 3-state functionality allows for multiple devices to share a common bus line without interference, a critical feature in complex digital systems where bus contention must be managed.

The device operates over a broad voltage range from 4.5V to 5.5V, and it is characterized for operation from -40°C to 85°C, making it suitable for commercial-grade applications. The SN74AHCT125DRG4's inputs are compatible with a wide range of input signal levels, including 5V TTL and 3.3V CMOS levels, providing a versatile interface solution.

Constructed using Texas Instruments' advanced high-speed CMOS technology, the SN74AHCT125DRG4 offers balanced propagation delays and low power consumption. This technology also ensures that the device has a significantly reduced crosstalk, which is essential for maintaining signal integrity in dense electronic systems.

The SN74AHCT125DRG4 comes in a compact SOP (Small Outline Package) with a 14-pin configuration, identified by the DRG4 suffix in its part number. This surface-mount package allows for efficient use of PCB space and is widely used in modern electronic assemblies.

Key features of the SN74AHCT125DRG4 include:

• 4 independent non-inverting buffer gates with 3-state outputs
