SN74LVT125DRG4 - Low-Voltage Quadruple Bus Buffer Gates with 3-State Outputs

The SN74LVT125DRG4 from Texas Instruments is a high-performance, quadruple bus buffer gate featuring 3-state outputs designed to operate as a quad buffer or line driver for standard bus driving with a 3.3V supply. This device is part of the LVT family, which means Low-Voltage BiCMOS Technology, offering both high speed and low power consumption. The SN74LVT125DRG4 is optimized for use in 3.3V systems but can also interface to 5V systems, making it highly versatile for mixed-voltage applications.

Each of the four buffers of the SN74LVT125DRG4 has a separate output-enable (OE) input, which when high, puts the respective output into a high-impedance state, allowing for bus-oriented applications. This feature is particularly useful when multiple devices are connected to a bus, as it prevents bus contention by ensuring that only one device drives the bus at a time.

The device is characterized for operation from -40°C to 85°C, making it reliable for industrial temperature ranges. Its low-voltage operation and low static power consumption make it suitable for battery-powered devices, portable electronics, and other power-sensitive applications.

Key features of the SN74LVT125DRG4 include:

• Support for mixed-mode voltage operation and voltage translation
• Low-voltage operation (VCC = 2.7V to 3.6V)
• High-drive outputs (-32mA IOH, 64mA IOL)
• Output ports have equivalent 26-ohm series resistors, so no external resistors are required
• Inputs accept voltages up to 5.5V, allowing interface with 5V logic levels
• Latch-up performance exceeds 250mA per JESD 17
• ESD protection exceeds JESD 22

The SN74LVT125DRG4 comes in a small-outline package (SOP) and is available in tape and reel, ensuring reliable and efficient assembly during the manufacturing process. Its small footprint and low profile make it suitable for space-constrained applications. Whether you're designing high-speed data paths, memory address drivers, or any application requiring a high-performance, non-inverting buffer, the SN74LVT125DRG4 is an excellent choice for your design needs.
