Key Features
- 4-channel unidirectional level translation at up to 200 Mbps, enabling high-speed interface bridging between 1.2V, 1.8V, 2.5V, and 3.3V logic domains
- Ultra-compact 14-pin WQFN package measuring only 3x2.5 mm, ideal for dense PCB layouts in mobile, wearable, and IoT device designs
- Active-high enable control pin supporting bus isolation and power sequencing in multi-voltage SoC and FPGA designs with minimal external components
Applications
The TXU0304BQAR is designed for high-speed unidirectional logic-level translation in portable consumer electronics, IoT modules, and embedded systems where 1.8V microcontrollers must interface with 3.3V sensors or peripherals. Its 200 Mbps data rate supports UART, SPI, and GPIO interfaces running at frequencies up to 100 MHz without signal degradation. The tiny 14-pin WQFN footprint and 5 pF load capacitance minimize parasitic capacitance on high-speed signal lines, making it ideal for battery-powered wearables and space-constrained PCB designs.

Frequently Asked Questions
What is the maximum data rate supported by the TXU0304BQAR level translator?
The TXU0304BQAR supports unidirectional data translation at up to 200 Mbps per channel, making it suitable for high-speed UART, SPI, and GPIO level shifting between 1.8V and 3.3V logic domains in embedded and IoT applications without introducing significant propagation delay.
Which voltage domains can the TXU0304BQAR translate between, and how many channels does it provide?
The TXU0304BQAR provides 4 independent unidirectional translation channels and can bridge logic levels across 1.2V, 1.5V, 1.8V, 2.5V, and 3.3V supply domains. The VCCA and VCCB pins set the input and output logic levels independently, supporting flexible mixed-voltage system designs with a single device.
How does the active-high enable pin on TXU0304BQAR benefit system power management?
The active-high enable pin allows the 4-output bus to be tristated when pulled low, enabling bus isolation during power sequencing or when the downstream device is powered off. This prevents back-powering through the 14-pin WQFN device and reduces quiescent current draw to near-zero in sleep modes for battery-powered applications.
For a compact wearable PCB layout, how much board space does the TXU0304BQAR require?
The TXU0304BQAR is housed in a 14-pin WQFN package measuring only 3x2.5 mm with a 0.5 mm pitch, occupying approximately 7.5 mm2 of PCB area. Combined with its 5 pF load capacitance per channel, it fits easily in wearable and mobile designs with constrained real estate and tight signal integrity budgets.
