Frequently Asked Questions
What is the operating supply voltage range of the SN74ALVC125DG4?
The SN74ALVC125DG4 operates from a supply voltage (VCC) of 1.65V to 3.6V, making it compatible with both 1.8V and 3.3V logic systems. This wide range allows it to serve as a buffer or level interface in mixed-voltage digital designs.
How many channels does the SN74ALVC125DG4 have and how are they controlled?
The SN74ALVC125DG4 has 4 independent non-inverting buffer channels, each with its own active-low output-enable pin (OE). When OE is high, the corresponding output is placed in a high-impedance 3-state condition, allowing multiple devices to share a bus without conflict.
What package and pin count does the SN74ALVC125DG4 use?
The SN74ALVC125DG4 is housed in a 14-pin SOIC (Small Outline IC) package, JEDEC code R-PDSO-G14. The SOIC-14 package has a standard 1.27mm pin pitch and is supplied in tube form, with a body width of approximately 3.9mm.
What logic family does the SN74ALVC125DG4 belong to and what are its speed characteristics?
It belongs to Texas Instruments' ALVC/VCX/A logic family, which offers low-voltage advanced CMOS performance. The ALVC125 achieves propagation delays under 3ns at 3.3V with a 50pF load, combining fast switching with low power consumption versus older LVTTL devices.
Is the SN74ALVC125DG4 RoHS compliant?
Yes, the SN74ALVC125DG4 carries a JESD-609 code of e4, indicating it is a lead-free, RoHS-compliant device. The 'G4' suffix in the part number also denotes the green/RoHS-compliant packaging qualification from Texas Instruments.
