Frequently Asked Questions
What is the operating voltage range of the SN74LV125ADB?
The SN74LV125ADB operates from 1.65V to 5.5V supply voltage, making it compatible with a wide range of modern low-voltage logic systems and legacy 5V designs.
What package does the SN74LV125ADB come in?
The SN74LV125ADB is available in a 14-pin SSOP (R-PDSO-G14) surface-mount package, which is compact and suitable for space-constrained PCB layouts.
How does the enable control work on the SN74LV125ADB?
Each buffer in the SN74LV125ADB has an active-low output-enable pin. When the enable pin is driven low, the corresponding output is active; when driven high, the output is placed in a high-impedance 3-state condition, allowing multiple devices on the same bus.
Is the SN74LV125ADB RoHS compliant?
Yes, the SN74LV125ADB carries a Pb-free code of 'Yes' and JESD-609 code e4, confirming it meets RoHS and lead-free soldering requirements for environmentally conscious manufacturing.
What is a common substitute for the SN74LV125ADB?
Compatible alternatives include the SN74LVC125A in a similar SSOP or TSSOP package from Texas Instruments, offering comparable 3-state bus buffer functionality with the same pinout and electrical characteristics.
