SN74LVT125NSR Quad Bus Buffer Gate with 3-State Outputs

The SN74LVT125NSR from Texas Instruments is a high-performance, four-line buffer gate that features tri-state outputs and is designed to operate from a 2.7 V to 3.6 V power supply, making it suitable for interfacing with 3.3 V logic in mixed 3.3 V/5 V systems. This device is optimized for use in high-speed signaling applications, which require a low-voltage interface that can still drive high-capacitance loads with minimal propagation delay and power consumption.

Each buffer gate of the SN74LVT125NSR has a dedicated output enable (OE) pin, which, when held at a high logic level, places the corresponding output in a high-impedance state. This feature allows for the disconnection of the output from the bus line, facilitating bus arbitration and preventing contention issues on shared lines.

The SN74LVT125NSR is characterized for operation from -40°C to 85°C, making it reliable in a wide range of environmental conditions. It is offered in a compact 14-pin NSOIC package, which is ideal for space-constrained applications such as portable electronics, computing devices, and telecommunications infrastructure.

Key features of the SN74LVT125NSR include:

• Support for mixed-mode voltage operation
• High drive capability with 24-mA output drive at 3.3 V
• Low power consumption with ICC of 20 μA maximum
• IOFF support to maintain low power consumption when the device is powered down
• Bus hold on data inputs to eliminate the need for external pull-up/pull-down resistors
• Latch-up performance exceeds 250 mA per JESD 17
• ESD protection exceeds JESD 22

This buffer gate is an essential component for system designers who require a robust and versatile interface solution. The SN74LVT125NSR is not only suitable for bus driving applications but also for buffering signals for data transmission, signal conditioning, and impedance matching. With its high-speed performance and tri-state functionality, the SN74LVT125NSR is an excellent choice for ensuring signal integrity in complex logic systems.
