Frequently Asked Questions
What is the operating voltage range of the SN74ALVC125DE4?
The SN74ALVC125DE4 operates from a supply voltage of 1.65V to 3.6V, making it suitable for low-voltage CMOS systems. It is compatible with 1.8V, 2.5V, and 3.3V logic families commonly found in modern digital designs.
What package does the SN74ALVC125DE4 come in and how many pins does it have?
The SN74ALVC125DE4 is housed in a 14-pin SOIC (Small Outline Integrated Circuit) package with a tube shipping format. The package code is R-PDSO-G14, providing a compact footprint suitable for surface-mount PCB assembly.
Can the SN74ALVC125DE4 be used for bus isolation in multi-master designs?
Yes, the SN74ALVC125DE4 is designed specifically for bus isolation with its active-low output enable (OE) pins, one per channel. When OE is high, the output is in a high-impedance 3-state condition, allowing multiple devices to share the same bus without signal contention.
What is the maximum output low current (IOL) for the SN74ALVC125DE4?
The SN74ALVC125DE4 supports a maximum output low current (IOL) of 24mA, enabling it to drive standard TTL and CMOS loads. This current capability is sufficient for most bus buffering and logic interfacing applications.
What are common alternatives or substitutes for the SN74ALVC125DE4?
Compatible alternatives include the SN74LVC125A (5V-tolerant inputs), SN74AHCT125 (AHCT logic family), and 74VHC125 from other vendors. The SN74ALVC125DE4 is specifically optimized for ultra-low-voltage operation and fast switching compared to standard LVC or HCT variants.
