Functional Features
- Quad bus buffer with 3-state outputs.
- Inputs and outputs are tolerant to 5.5V, allowing for direct interface with TTL/CMOS devices.
- Provides non-inverting buffer functions.
- Outputs can be disabled using the output enable (OE) input, which puts them in a high-impedance state.
Advantages and Disadvantages
Advantages: - Low voltage operation makes it suitable for battery-powered applications. - High-speed operation allows for efficient signal buffering. - 3-state outputs provide flexibility in controlling signal flow.
Disadvantages: - Limited output drive capability compared to some other buffer ICs. - Not suitable for high-voltage applications.
Working Principles
The 74LVT125PW,112 operates by receiving digital signals at its input pins (A1-A4) and buffering them to the corresponding output pins (Y1-Y4). The output enable (OE) input controls whether the outputs are active or in a high-impedance state. When OE is low, the outputs are enabled and mirror the input signals. When OE is high, the outputs are disabled and enter a high-impedance state.
Detailed Application Field Plans
The 74LVT125PW,112 is commonly used in various applications, including: - Microprocessor systems - Data communication systems - Networking equipment - Industrial automation - Consumer electronics
