Frequently Asked Questions
What is the supply voltage range of the SN74LVC1G125DRLR?
The SN74LVC1G125DRLR operates over a supply voltage range of 1.65V to 5.5V, making it compatible with 1.8V, 2.5V, 3.3V, and 5V logic families commonly used in modern embedded and portable systems.
How does the output enable control work on the SN74LVC1G125DRLR?
The device uses an active-low enable input (OE#); when driven low, the output follows the input signal. When driven high, the output enters a high-impedance (tri-state) mode, disconnecting the device from the bus and preventing signal contention.
What package does the SN74LVC1G125DRLR use?
It is housed in a 5-pin SOT-5X3 (R-PDSO-F5 / SC-74A) flat-lead SMD package, which measures approximately 1.6 mm x 1.6 mm, providing an ultra-compact footprint for space-constrained PCB layouts.
Is the SN74LVC1G125DRLR RoHS compliant?
Yes, the SN74LVC1G125DRLR carries Pb-free (RoHS-compliant) designation with JESD-609 code e4, confirming it is manufactured without restricted hazardous substances, suitable for products sold in regulated markets worldwide.
What are typical applications for the SN74LVC1G125DRLR?
Typical applications include bus buffering on SPI, I2C, and UART interfaces, level shifting between logic domains, GPIO signal isolation, and signal fan-out in portable electronics, industrial controllers, and communication modules.
