Overview
The SN74LV4T125RGYR, produced by Texas Instruments, is a single power supply quadruple buffer gate designed for a wide range of voltage levels. This CMOS logic device operates within a voltage range of 1.8 V to 5.5 V, making it versatile for various applications including portable, telecom, industrial, and automotive systems. The device supports level translation, enabling it to translate input signals up or down to match the output voltage level, which is referenced to the supply voltage (VCC). This feature is particularly useful in systems where different voltage domains need to communicate effectively.
