Description and Introduction

Quad TRI-STATE Buffer The 54LS125 is a quad bus buffer gate with 3-state outputs, manufactured by Texas Instruments. It is part of the 54LS series, which is designed for military and aerospace applications, offering a wider temperature range and higher reliability compared to commercial-grade components. Key specifications include:

- **Logic Family**: 54LS (Low-power Schottky)
- **Number of Gates**: 4
- **Output Type**: 3-state
- **Supply Voltage Range**: 4.5V to 5.5V
- **Operating Temperature Range**: -55°C to +125°C
- **Propagation Delay**: Typically 15 ns
- **Input Current (High)**: 20 µA (max)
- **Input Current (Low)**: -0.36 mA (max)
- **Output Current (High)**: -2.6 mA (max)
- **Output Current (Low)**: 24 mA (max)
- **Package Type**: Ceramic Dual-In-Line (DIP)

The 54LS125 is designed for use in bus-oriented systems where multiple outputs are connected to a common bus, and the 3-state outputs allow for high-impedance states to prevent bus contention.
