The TXS0108EQPWRQ1, a high-speed bidirectional voltage-level translator, is a versatile device for translating either one or two channels of data. With a transfer rate of 250,000 bits per second (bps), the device is designed for applications that require low-power, low-voltage level shifting. The TXS0108EQPWRQ1 is suitable for applications such as multi-voltage buses, memory power management, wired or wireless communication, analog signal conversion and power management.

TXS0108EQPWRQ1 is part of the family of logic translators, level shifters which includes dual-channel devices that can provide more flexibility than a single-channel device. The design of the devices allows for high-speed bidirectional communication and low voltage conversion with little or no interface penalty. The TXS0108EQPWRQ1 can be used to provide level-shifting between low-voltage buses and any low-voltage protocol with a range of 0.6 V to 3.6 V.

The TXS0108EQPWRQ1 features three power management functions: power-on-reset (POR), programmable input pre-driver and power-down mode. The POR circuit ensures that ICs are reset at power-on and the inputs pre-drivers passively improves the logic transition speed by providing a two-stage driver for output transitioning. The power-down mode reduces the active power consumption by disabling the internal driver and POR circuits.

The working principle of the TXS0108EQPWRQ1 is based on positive feedback. The device is a differential amplifier, with two input lines of the same amplitude and one output line. The differential amplifier amplifies the difference between the two input lines and the output is a function of the ratio of the differential pair of transistors. The feedback resistor is connected in a manner such that the output voltage of the amplifier is dependent on the difference between the two inputs.

The TXS0108EQPWRQ1 has two channels which integrate both a “gain” stage with a “buffer” stage. The “gain” stage, called the “amplification stage”, is used to amplify the input signal before the signal is passed to the output stage. The “buffer” stage is used to isolate the input signal from the output signal so as to reduce any signal distortion. The two channels are configured in such a way that each channel is working independently of the other.

In addition, the TXS0108EQPWRQ1 device offers flexibility through programmability. Outputs can be programmed individually to provide a higher speed of the logic rising and falling edges. Also, the input pre-drivers can be used to reduce voltage transition times for low power applications and will reduce the overall power consumption. The device also allows for data changes during transition, so that data will be delivered in both directions without waiting for the POR circuit to be reset.

In conclusion, the TXS0108EQPWRQ1 is a cost-effective, versatile and robust logic translator, level shifter. It features low-power consumption and high-speed operation, and offers both single and dual channel devices which can be tailored over multiple voltage channels. The device also offers flexibility as a programmable device, allowing for high speed operation and low-frequency modulation of data.
