Frequently Asked Questions
What supply voltage range does the SN74AUP2G125RSER support?
The SN74AUP2G125RSER operates from a supply voltage range of 0.8V to 3.6V, making it compatible with 1.8V, 2.5V, and 3.3V logic systems commonly found in modern microcontrollers, FPGAs, and processors. This wide range is essential for IoT and wearable applications where diverse supply voltages are used.
What is the maximum output drive current of the SN74AUP2G125RSER?
The SN74AUP2G125RSER provides a maximum output low current (IOL) of 4mA. This relatively low drive current is consistent with the ultra-low-power AUP family design goal of minimizing bus power consumption in battery-operated and energy-harvesting systems.
What package is the SN74AUP2G125RSER in, and how small is it?
The SN74AUP2G125RSER is housed in an 8-pin QFN (Quad Flat No-lead) package with a very compact footprint. The QFN package provides excellent thermal performance and a small PCB area, making it suitable for space-constrained wearable electronics, portable medical devices, and miniaturized IoT hardware designs.
Is the SN74AUP2G125RSER bidirectional?
No, the SN74AUP2G125RSER is a unidirectional bus buffer, meaning signals flow in one direction from input to output. The 3-state output enable allows the outputs to be placed in a high-impedance state for bus sharing. For bidirectional applications, a bus transceiver such as the SN74AUP2G241 would be more appropriate.
