Frequently Asked Questions
What is the supply voltage range of the SN74LVC1G125DBVT?
The SN74LVC1G125DBVT operates over a wide supply voltage range of 1.65V to 5.5V, making it compatible with 1.8V, 2.5V, 3.3V, and 5V logic families. This flexibility allows it to be used in mixed-voltage system designs without level-shifting issues.
What does the 3-state output mean on the SN74LVC1G125DBVT?
The 3-state (tri-state) output means the device can be placed into a high-impedance state by asserting the active-high output enable (OE) pin low. In this state, the output is effectively disconnected from the bus, allowing multiple devices to share a common data line without conflict.
What package does the SN74LVC1G125DBVT use and what are its dimensions?
The SN74LVC1G125DBVT comes in a SOT-23-5 (DBV) package, which is a 5-pin small-outline transistor footprint measuring approximately 2.9mm x 1.6mm. This compact size is ideal for space-constrained PCB layouts in portable and wearable electronics.
What are common applications for the SN74LVC1G125DBVT?
Common applications include bus buffering in microcontroller systems, signal isolation between 1.8V and 3.3V domains, SPI and I2C line multiplexing, FPGA I/O expansion, and general-purpose logic buffering. The device is especially popular in IoT, mobile, and embedded designs requiring low power and small package size.
