• Robust output current capability for driving capacitive loads

Advantages and Disadvantages

Advantages: - High-speed signal buffering and driving capabilities - Low-power consumption - Tri-state output for flexible control - Wide supply voltage range - Robust output current capability

Disadvantages: - Limited number of buffers/drivers (4 in total) - Not suitable for high-voltage applications

Working Principles

The 74V2T125STR operates as a non-inverting buffer/driver, which means that the input signal is reproduced at the output with the same logic level. The tri-state output feature allows the user to disable the output stage, effectively disconnecting the output from the rest of the circuit.

When the output enable (OE) pin is set to a logic high level, the outputs are enabled and actively driven according to the input signals. Conversely, when the OE pin is set to a logic low level, the outputs are disabled and enter a high-impedance state, allowing other devices to drive the bus lines.

Detailed Application Field Plans

The 74V2T125STR can be used in various digital applications, including but not limited to: - Data communication systems - Microprocessor-based systems - Memory interfaces - Industrial automation - Consumer electronics
