Logic - Buffers, Drivers, Receivers, TransceiversThe 74LVTH125DB,118 is a quad general-purpose buffer/driver, which is ideal for low-voltage, high-performance applications. Its versatility and low power consumption makes it a popular choice in many systems, including personal electronics, computers, and industrial equipment.

Features

This device is made up of four independent buffers and drivers. The device is fast and has a high fan-out capability. It is typically used to reduce loading of data bus or to drive address latch enabling (ALE) in order to interface a microprocessor or similar circuits with another device in a three-state output mode driving capability.The device features Schmitt trigger inputs. This helps to provide increased noise immunity by providing greater hysteresis, allowing the device to reject fast transitions from high to low. The device also has output disable control. The outputs can be disabled simultaneously by tying the output enable (OE) pin high.The device is designed with low power consumption in mind. The power supply voltage range of 2.0 Volts to 3.6 Volts and the low power consumption of only 300 uA for 3.3V operation, make it ideal for battery-powered devices.

Pin Configuration

The device has an 8-pin package. The pins are numbered 1 – 8 in a left-to-right sequence, as seen in standard logic packages. Pin 1 is connected to the Vcc pin, while Pin 8 is connected to ground (Gnd). Pins 2 and 4 are inputs, while Pins 3, 5, 6, and 7 are all outputs. The output enable (OE) pin is located between Pins 3 and 5, while the input pull up pin (PU) is located at the end of the sequence.

Application

The 74LVTH125DB,118 is designed for high-speed, low-power applications. The device can be used for a variety of tasks, such as driving a microprocessor address lines, reducing loading of data bus, or interfacing with a three-state output mode driving capability. It is suitable for operating in both commercial and industrial temperature ranges. The device has three supply voltage ranges, allowing it to be used in a variety of applications. The device can be used in logic-level translation (low-voltage to high-voltage conversion) as well as in level shifting applications. The device has a low switching speed, making it well suited for bus-oriented systems and low-rate data paths. It is also ideal for low-frequency circuit applications, such as automotive applications.

Working Principle

The working principle of the 74LVTH125DB,118 is based on a four-state device architecture. Each internal buffer/driver is made up of two CMOS transistors. When the input (D) is low, both transistors are off and the output (Q) remains high. When the input (D) is high, the top transistor turns on and pulls the output (Q) low. When the output enable (OE) pin is low, both transistors are off and the output (Q) is high impedance. The device is able to process signals faster than the Schmitt trigger input level thresholds, allowing it to accept fast input transitions without generating false transitions. When the trigger input level thresholds are reached, the device switches states. The output enable pin controls the voltage on the output pins by turning off both transistors when the pin is high. This ensures that the outputs are in a high impedance state when the outputs are disabled. The device also has a pull up pin (PU) that can be used to set the input signal high. This pin can be used to set the input to a high logic level when the input signal is not being driven by another circuit.

Conclusion

The 74LVTH125DB,118 is a highly versatile quad general-purpose buffer/driver. It has a wide range of supply voltage, making it suitable for a variety of applications. It is fast, has a high fan-out capability, and consumes low power, making it ideal for low-voltage, high-performance applications. Its Schmitt trigger inputs, output disable control, and pull up input pin make it a popular choice in many systems, including personal electronics, computers, and industrial equipment.
