Frequently Asked Questions
What is the supply voltage range of the 74LVC1G125DRLR?
The 74LVC1G125DRLR operates over a wide supply voltage range of 1.65V to 5.5V, making it compatible with modern low-voltage systems (1.8V, 2.5V, 3.3V) as well as legacy 5V logic environments. This flexibility allows it to serve as a voltage-level translator in mixed-supply designs.
What does the 3-state output mean and how is it controlled?
The 3-state (tri-state) output can be placed in a high-impedance state by asserting the Output Enable (OE) pin low, effectively disconnecting the output from the bus. When OE is high, the buffer drives the output normally. This feature is essential for bus-sharing applications where multiple devices share the same signal line.
What package does the 74LVC1G125DRLR use and what is its footprint?
The 74LVC1G125DRLR comes in the DRL package, which is a 5-pin SOT-553 flat-lead surface-mount package. This package measures approximately 1.6mm x 1.2mm, making it one of the smallest form factors available for single-gate logic, ideal for compact PCB layouts in wearables and portable devices.
What are common applications for the 74LVC1G125DRLR?
Common applications include signal buffering between microcontrollers and external peripherals, voltage-level translation between 1.8V and 3.3V domains, bus isolation in multi-master systems, and output driving in IoT sensor nodes. It is also used in smartphones, tablets, and industrial control systems requiring a compact, low-power buffer solution.
Is the 74LVC1G125DRLR compatible with 5V-tolerant inputs?
Yes, the 74LVC1G125DRLR features 5V-tolerant input pins, meaning the input can safely accept signals up to 5.5V even when the device is powered at a lower supply voltage such as 1.8V or 3.3V. This makes it particularly useful for interfacing modern low-voltage MCUs with legacy 5V peripheral devices.
