Buffer integrated circuits are devices that provide logic elements with the capability to drive an output control across transmission media with minimal distortions and noise. Buffer circuits also have the effect of changes in the input logic level to its corresponding output logic levels with minimal delay.

The 74LVT245SJX buffer is an SN74LVT245 advanced low-voltage, high-current, low-power buffer/driver IC with three-state outputs. It is designed to develop a wide range of applications such as bus-buffering, cable driver, data transfer, and interfacing between logic levels with different voltage and current levels.

Application Field

The SN74LVT245 advanced low-voltage, high-current bidirectional buffer is capable of providing a high-current sink and source output. It is ideal for low-voltage/flexible bus-buffering, data transfer, and also acts as interfacing device between different voltage levels. It is extensively used to drive low-power devices such as resistors, capacitors, and LEDs.

The SN74LVT245 buffer can also be used in cable drivers and digital video standard transmission lines like HD-SDI (High Definition Serial Digital Interface) and analogue video-based networks such as HDMI (High Definition Multimedia Interface). Furthermore, its output drivers are designed to source and sink current at 16mA. SN74LVT245 also comes with pin-compatible buffers which complies to the common 24-pin industry standard packages.

Working Principle

The SN74LVT245 buffer is an advanced low-voltage, high-current, low-power buffer/driver integrated circuit. It comprises of 20 bidirectional buffer with three-state outputs. All buffer inputs are individually controlled by the input enable (Gyr) pins and the outputs are controlled by the output enable (Gyy) pins. The output drivers are designed to sink and source current at 16mA and are actively disengaged in the power off mode.

The SN74LVT245 is capable of driving multiple receivers on the same bus and includes an active high-impedance three-state outputs. All buffers have specified power-up and power down characteristics and allow for both high- and low-power applications and operation. The maximum voltage swing of each output is ±5V and the maximum error of VOH to VOHOUT is 2.5V. SN74LVT245 is capable of operating from a single 5V supply with a maximum standby current of 10mA.

Conclusion

The SN74LVT245 buffer is an advanced low-voltage, high-current, low-power buffer/driver IC with three-state outputs. It is designed for a wide range of applications such as bus-buffering, cable driver, data transfer and interfacing between different logic levels with different voltage and current levels. The SN74LVT245 buffer is capable of providing a wide range of features including high-impedance three-state outputs and operation from a single 5V supply with a maximum standby current of 10mA.
