Frequently Asked Questions
How broad is the supply range for SN74LV125ADB level-compatible logic designs?
SN74LV125ADB operates from a 1.65V to 5.5V supply range, making it useful for mixed low-voltage logic rails and 5V-tolerant system planning.
Which output-control behavior should firmware and hardware teams expect?
The part is a quad bus buffer with 3-state outputs and enable-low control, so each channel group can isolate bus signals during inactive states.
What package and board footprint information matters for layout release?
The fetched context lists a 14-pin SSOP package with JESD-30 code R-PDSO-G14, so footprint and assembly drawings should match that package family.
Which load and drive values help qualify this buffer for signal routing?
SN74LV125ADB is associated with 50pF load capacitance and 16mA output current, useful figures when checking timing margin and fanout.
