Product Overview: SN74HC125DRE4 by Texas Instruments

The SN74HC125DRE4 is a high-performance, quadruple bus buffer gate with 3-state outputs, designed and manufactured by Texas Instruments (TI). This integrated circuit is part of the 'HC' family, which indicates it is a high-speed CMOS device. It is specifically engineered to provide a set of four independent buffer gates with 3-state outputs to ensure the capability for bidirectional data flow and bus management in digital systems.

Key Features

• Wide Operating Voltage Range: The SN74HC125DRE4 operates over a wide voltage range from 2 V to 6 V, making it compatible with a variety of logic levels and providing design flexibility for mixed-voltage system environments.
• High-Current 3-State Outputs: The outputs can drive up to 5.2 mA at 5 V, allowing for direct drive of small loads and effective interfacing with bus lines in a 3-state mode.
• Low Power Consumption: Characterized by low quiescent power consumption, this device is suitable for power-sensitive applications, contributing to overall energy efficiency.
• High Noise Immunity: A characteristic of the HC family, the SN74HC125DRE4 has a balanced noise immunity of 30% of the supply voltage, providing reliable operation in electrically noisy environments.

Applications

The versatility of the SN74HC125DRE4 makes it suitable for a broad range of applications, including:

• Bus driving where 3-state outputs are essential
• Memory address drivers
• Data transmission and multiplexing
• Input/output port expansion
• Line drivers with high-current output capability

Physical Packaging

The device comes in a small-outline package (SOP), specifically in a tape and reel format for automated assembly processes. The SN74HC125DRE4 is provided in the 14-pin SOP (SOIC) package, which is suitable for surface-mount technology (SMT), facilitating efficient use of board space in compact electronic designs.

Quality and Reliability

As with all Texas Instruments products, the SN74HC125DRE4 is designed to meet high standards of quality and reliability. It is RoHS compliant and is designed to meet or exceed industry standards for performance and longevity.
