Frequently Asked Questions
What is the operating voltage range of the SN74LVC125APWRG3?
The SN74LVC125APWRG3 operates from 1.65V to 3.6V VCC. Its inputs are 5V-tolerant, making it suitable for interfacing 3.3V logic with legacy 5V systems without additional level-shifting components.
What does the 3-state output mean and when should I use it?
3-state (tri-state) outputs can be driven high, low, or placed in a high-impedance state. When the active-low OE pin is pulled high, the output disconnects from the bus, allowing multiple devices to share the same bus lines without contention. This is essential in shared-bus designs such as memory expansion or multiplexed data lines.
What package does the SN74LVC125APWRG3 use and what is the pin count?
The SN74LVC125APWRG3 comes in a 14-pin TSSOP (JESD-30 code R-PDSO-G14) package. The PWRG3 suffix indicates it is a tape-and-reel, green (Pb-free, RoHS-compliant) variant, suitable for high-volume automated assembly.
Can the SN74LVC125APWRG3 replace SN74LVC125A in other package variants?
Yes, the SN74LVC125APWRG3 is electrically identical to other SN74LVC125A variants. It shares the same schematic symbol and logic function; only the package and ordering suffix differ. Common alternatives include SN74LVC125ADBR (SSOP-14) and SN74LVC125APWR (standard TSSOP tape-and-reel).
