Product Overview: 74LVC1G125DCKRE4

The 74LVC1G125DCKRE4 is a single bus buffer gate with 3-state output from Texas Instruments, designed to operate from 1.65 V to 5.5 V. This makes it suitable for interfacing with 5 V logic levels to 3.3 V logic levels. The device is part of the 74LVC family, which is well-known for its low-voltage operation and low power consumption.

Featuring a high-drive output (-32 mA I_OH, 32 mA I_OL), this buffer gate is capable of driving heavy loads with ease. The 3-state output allows the device to be used in bus-oriented applications by enabling or disabling the output function. When the output enable (OE) input is high, the output is in the high-impedance state, which effectively disconnects the output from the bus.

Key Features

• Wide Supply Voltage Range: Operates from 1.65 V to 5.5 V, making it versatile for various logic level integrations.
• High-Drive Outputs: -32 mA I_OH, 32 mA I_OL for driving heavier loads.
• 3-State Output: Allows for bus disconnection when necessary, improving signal integrity.
• Low Power Consumption: A characteristic of the 74LVC family, it has a reduced power footprint making it ideal for power-sensitive applications.
• Compatibility: Input levels are compatible with 5 V CMOS and TTL levels to ensure easy integration with existing technology.
• ESD Protection: Human Body Model (HBM) exceeds JESD 22, providing robustness for handling and assembly processes.
• Small Package: Available in a small SC70 (DCK) package, it is optimal for space-constrained applications.

Applications

The 74LVC1G125DCKRE4 is ideal for a wide range of applications, including:

• Logic level shifting for interfacing different voltage domains
• Bus isolation and bus line driving
• Memory address buffering
• Control line buffering
• General purpose buffering

With its combination of features, the 74LVC1G125DCKRE4 from Texas Instruments is a reliable and efficient solution for designers who require a single buffer gate with high-drive capability and 3-state output functionality.
