Frequently Asked Questions
What is the supply voltage range of the SN74ALVC125DRG4?
The SN74ALVC125DRG4 operates from 1.65 V to 3.6 V, making it compatible with both 1.8-V and 3.3-V logic systems and allowing direct level interfacing between them without additional translation circuitry.
How many channels does the SN74ALVC125DRG4 have and how is output enable controlled?
The device has 4 independent channels, each with an active-low output enable pin (OE). Asserting OE low drives the output; releasing it high places the output in high-impedance (3-state), preventing bus contention in shared bus topologies.
What is the maximum output current of the SN74ALVC125DRG4?
Each channel can sink a maximum output low current (IOL) of 24 mA at 3.3-V supply, which is sufficient to drive typical bus loads including 50-pF capacitive loads and standard CMOS/TTL inputs simultaneously.
What package does the SN74ALVC125DRG4 come in?
It is available in a 14-pin Small Outline IC (SOIC) package with green/RoHS-compliant JESD-609 code e4 marking, which is a widely supported package for automated PCB assembly and rework.
Can the SN74ALVC125DRG4 replace 74LVC125 or 74VCX125 devices?
Yes, the ALVC family is functionally and pin compatible with 74LVC125 and 74VCX125 buffers. The ALVC variant offers comparable speed and drive strength, so it is a direct drop-in replacement in most 3.3-V and 1.8-V buffer designs.
